In BPM 8.6 we moved to continuous delivery support.
https://www-01.ibm.com/software/support/lifecycle/cd-policy.html
8.6 has 3 years of standard support and at least 1 year of extended support.

What is BPM 8.6?
1. Just released in Sept, 2017
2. In-place upgrade from all prior BPM 8.5.x releases
3. BPM 8.6 can be considered as CF 2017.09 - Subsume BPM 8.5.7 as the next Cumulative Fix
(CF) in the BPM continuous delivery pipeline.
4. BPM 8.6 is on a continuous delivery licensing terms with a new support lifecycle (3 years
standard support + 1 year extended support).
5. Support Java 8 only - end of support for Java 6 (April, 2018), and Java 7 (Sep 2019).
6. Simpler licensing scheme
1. Both Standard and Advanced features are included in the same license
2. Process Server and Process Center have the same price
3. No separate license required for web Process Designer
4. Eclipse Process Designer and Integration Designer will still require separate licenses.
7. Faster than 8.5.x - based on BPD, Ad-hoc and BPEL benchmark

Migration and Upgrade
Definitions

Migration and Upgrade
Definitions
• Product Migration – BPM version migration, requires separate install of new BPM version,
configuration of topology and moving/migrating applications and perhaps data.
• Product Upgrade – BPM version upgrade, which is an in place fixpack on existing BPM
version. Same cell, same applications, same data.
• Topology Refactoring – Changing topology, hardware, or database, but the same BPM
product version.
• Application Versioning – Enhancing or fixing Process Apps (snapshots), updating toolkits
(libraries), or any other part of the application code.
• Process Instance Migration – After deploying a new process version (snapshot), moving
the runtime data (process state) from the older process version to the newer process version.

General Strategy and
Improvements

Migration Strategy & Major Enhancements
• Product Migration – Reducing frequency of migration from of every 1-2 years of product migration,
we’re aiming for 5-6 years. Federated Portal Server since 8.5.6 and federated API.
Migration checklist, interactive migration guide. Reduce risk with DB clone since 8.5.5. App-by-app
migration (services asset).
Standardized license entitlement up to 18 months.
• Product Upgrade – Every version since 8.5.0.0 has been an upgrade, including 8.6. This will
continue until v9.
• Topology Refactoring – In 8.5 we introduced topology refactoring for adding or changing hardware,
but the same BPM product version. BPM Config tool.

Reducing the need for migration
• Upgrade strategy - Since 8.5.0, we have followed an "update only"
constraint on every new 8.5 release. This has resulted in upgrade only
infrastructure since 8.5.0 (June 2013) that will continue until we reach BPM
9. This is at least 5 years of upgrades only. Compare that to the previous
years where we forced a migration each year (every release).
• Federated API Server - In 8.5.6 we introduced a federated portal that
aggregates the information from cells of different BPM versions. This is key
to our strategy going forward as we release new versions. This way you
can let their existing applications and process instances drain from older
cells and start new processes in the new cell. This would greatly reduce the
need for application migration.

18
Migration Improvement Details
Infrastructure migration/update
In 8.5 we drastically simplified the infrastructure, improving the standardization and as a result
improved the testing coverage. We went from 9700 permutations to about an order of magnitude
fewer. Likewise we went to a central configuration file (BPMConfig).
To help with migration we have created config extraction tools that take from older versions, display
the configuration graphically for modification, and allow creation of new environments from this file.
For ifixes and fixpacks, we have been working on simplifying the ifix updates so that include the
dependency trees, making applying them simpler.
Migration checklist - we now include a migration checklist to check for the infrastructure.
DB clone - since 8.5.5 we support DB cloning for migration. This greatly reduces risk as customers
can migrate to a cloned DB and if there are any issues they can just point to the original DB.
iFix Bundle – with 8.5.6, we started bundling groups of iFixes into a single bundle that can be
installed quarterly.
Fixpack strategy - Since 8.5.0 we have been including all fixes in the next feature release. This
increases quality for our customers as we are reducing the number of code streams that we have to
support and test, allowing us to be more thorough testing.

19
Migration Improvement Details
Application migration
We have been stabilizing the programming models over the last 5 years, making fewer
changes in each release. As a result, application migration is simpler for customers
moving from later releases.
App-by-app migration [Services Asset]
In 8.5.6 we introduced a services asset the app-by-app migration for BPMN only. This will
give business more flexibility as they won't have to migrate the entire infrastructure, but
rather could focus on one or two process applications that need the latest infrastructure.
Can move SQL Server->DB2 or Oracle->DB2. Only works for 8.5.6 and 8.5.7.
Instance Migration
We continue to improve the performance of instance migration which will allow for shorter
time windows when applications are updated and older instances are migrated to the
latest snapshot. In the latest release it is an order of magnitude faster than in 8.5.6 due
to parallelism in both local threads and multiple nodes.

18 month entitlement
License
We recognize that the SWG standard of 90 day dual entitlement
may not suffice for large BPM deployments doing BPM Version
to Version system migrations with long running processes and in
this case have a pre-approved, 18 month extended migration
agreement that can be offered. Link to information:

still use IID 8xx and manually update the applications to get it working on the latest BPM
level, and then use the “drain” approach (see later charts for details).

Upgrade Rules of Thumbs
1. You can use a “rolling upgrade” methodology to upgrade your BPM ecosystems.
a. In-place Rolling Upgrade
b. Side-by-side Rolling Upgrade
2. Do not upgrade your Process Center (Dev environment) until you have at least proved that the
upgrade is working in your QA environment.
3. The version of Process Designer and Integration Designer must match the version of the Process
Center.
4. The version of Process Center and Process Server must match in order for the Process Server to
be connected as “online”.
5. An application that you developed using an older version of the BPM product can be deployed to
run on a newer version of BPM as long as it is not using features that have been removed.
6. We strive to maintain API compatibility in BPM mod and fixpack releases.
7. In BPM 85xx, we enabled the support of online rolling upgrade:
a. BPM 8500 Process Designer and Integration Designer to connect to BPM 8501 of Process
Center and Process Server (for debugging).
b. A BPM 8501 Process Server can connect as “online” mode to BPM 8500 Process Center.
c. The purpose to facilitate debugging of upgraded application and allow a more gradual roll
out of the upgrades.

Process – In-Place Rolling Upgrade
start
Certify PS
<Test> end
Certify PS
<Staging>
Certify PS
<Prod>
Certify PC
In this procedure, we will upgrade PS first.. From <Test> to <Prod>, and finally upgrade PC.
Pros:
1.Upgrade and certify one Process Server environment at a time in an orderly fashion.
2.Upgrade PC last as we want to ensure we can continue to provide fixes to PS running at current
version.
Cons:
1.Upgrade PC last means developers cannot utilize new features until the entire eco-system is
upgraded.
2.With the exception of 8501, any other upgrade would force the PS to go offline to the down-level PC,
thus requiring offline deployment until the PC is upgraded.
We should always take a full backup of your environment before the upgrade, this allows up to restore
any environment during this period in order to deliver a hot-fix of your application to your <Prod>
environment before your <Prod> environment can be upgraded.

Process – Side-by-Side Rolling Upgrade
start
Side-by-side

Certify and
Re-target PS
<Staging>
Certify PS
<Prod>
In this procedure, we will setup a new “upgraded” PC side-by-side, and then proceed to upgrade each of the PS
environment.
Pros:
1.An “upgraded” PC is available immediately for new development and tests
2.Customers can certify new product version on a per-application basis without impacting existing development and
test.
3.All Process Server environments can maintain “online” status all the time.
Cons:
1.Setup a side-by-side “upgraded” PC will require additional IT resources and may incur additional licensing cost.
2.May require more work if the customers’ configuration is not well documented.
3.Depending on the approach to setup the side-by-side PC, one will lose existing “playback” instances data.

Managing fixpack upgrade downtime
By performing some upgrade tasks in parallel, we can reduce the time it took
to upgrade. In this example, we are upgrading to 7.5.1.2.
Upgrade from 7.5.1.x to 7.5.1.2 Time
• update Installation Manager
• backup configuration
1 – 2 min
(in parallel)
• update Deployment Manager and Nodes
using a “staggering” approach with 10 min
delay between each node.
60 min
• upgrade clusters
• upgrade database
10 min
Total 72 min*
•Time is taken based on a test system with 3
nodes. The actual time will depend on a number of
factors such as disk access time, network latency,
CPU speed, etc.
• For upgrade from 7.5.0.0, you can expect more
time is needed for updating the individual node.

Migration Approach
Drain - Application migration and “drain” existing instances
• Let existing instances in V-old run to completion, start new instances in V-new
system.
Runtime Migration - Application migration followed by Runtime migration
• Once ALL applications are working in V-new, convert the existing database to
make it compatible with V-new in one shot.
Milestone Transfer - Transfer process state mid-stream using custom logic to
new version.
• A variation of the “Drain” approach.
• Let existing instances in V-old run to a designated set of business milestones,
start new instances in V-new system from those milestones.

What to Migrate?
Pros Cons
Artifacts Only
Migration
(Drain or
Milestone
Transfer)
Start with a clean database. Leave messy
data behind.
Parallel production environment allows for
app-by-app migration and no production
downtime.
Process history are not transferred to the
new system.
Parallel production environment requires
additional maintenance and resources.
Business Data
and Applications
Migration
(Runtime
Migration)
Source environment applications and data
are migrated to the target environment.
Process and human tasks can start in the
source environment and complete in the
target environment.
Bringing over all data depending on size
and complexity can increase migration
risks which requires additional testing.
Downtime required. All applications must
be ready before you can start migrating
the system.

Process Center Migration
Observing that Process Center contains “playback” instances only, there is really no
business needs to migrate “playback” instances to the new product version. Based on this
assumption, we are simplifying the Process Center migration to application-only migration.
• Setup a new PC target environment with new database.
• Migrate individual application artifact by exporting “active” snapshots from source
environment to target environment in chronological order.
• Runtime data (instances, tasks, tracking groups, etc) and offline server deployment
information will not be migrated.
Advantages:
• One can setup Process Center right away and start working on application migration.
• Application can be moved to new product version one application at a time.
• Existing V-old Process Center is still available to handle fixes for production system.
• No downtime for Process Center.
Not applicable if
Process Center is not
used in your system.

BPM 8.5.5/8.5.6/8.5.7/8.6 Migration Enhancements
Improve migration robustness, ease-of-use and planning
• Revised documentation with enhanced interactive migration guide and guidance on migration methodology to better guide
customers and services on how to plan their migration project.
• Migration Pre-Validation Tool + Post-Validation Health Center
• Pre-check and report migration potential failures
• Save cost of migration late phase failure, recovery and redo
• Post-Validation via BPM Health Center, speed up target environment health check
• Easier environment setup via Configuration Migration Tool
• Migration paths support with a target environment that is set up with about 400 source-environment basic properties around
database, security, and the most important performance parameters to the client’s environment.
• Reduce about 50% post-migration actions on properties
• Separate tool can export/import WAS application level configurations which are not owned by the BPM, like: data source,
auth-alias, SSL settings
Speeding up migration
• Quicker migration via multi-thread enablement
• Migration from BPM v7.5.1 migration shows 2x ~ 3x improvements
• Migration from TW v6.2 migration can see up to 20x improvements
36

• Help you determine the expected document that matches your migration
scenario, save your effort to search infocenter and navigate between
different topics.
37
Two steps wizard

Validate source environment before migration
• We introduced migration pre-validation tool to help you find potential
issues before real migration, and what you should take care during
migration
• Validate current environment to make sure it’s ready to do migration
• Read required information that will be used in latter migration steps
• Show error if it’ll block migration, or the source environment isn’t in the
expected status
• Show warning if you need to take care before or after migration
• Show warning if there is some big number of data will have performance
impact during migration

Wang Lei ok, thanks 4:53:22
PM

Cleaning up before migration
The more data we have in the BPM system, the longer it will take migration to run.
So it is important that before we run migration, remove information that are not
required anymore in the new system.
• ProcessInstancesCleanup command to remove “completed” process instances.
• Performance Data Warehouse prune command for removing PDW data.
• BPMDeleteDurableMessages command to remove durable events that are no
longer needed.
46

BPM Health Center
• Check the health status of the deployment environment after migration,
should be the first step to validate migrated environment before other
planned testing
47

App-by-App (IBM Lab Services Asset) for BPM
Standard – 8.5.6 and 8.5.7 only.
Support selective migration of applications runtime data
1. Selective migration
1. Only move certain applications
2. Only move the data which need keep in the new environment by the time range
3. Only move the system data like users, groups, user-group-relationship, user attributes, etc
2. Splitting of deployment systems
1. Refine the deployment design
2. Scaling out application
3. Database vendor conversion - other databases move to DB2
What this is not intended for:
1.Temporary move of applications for the isolation and then moved back
2.Massive restructuring of the BPM environments
3.Move applications freely among different BPM environments
4.Move advanced data (BPEL)
48

App-by-App compare with runtime migration
Pros Cons
App-by-app
Migration
1. Migrate one BPM Standard application at a time
to the new system to reduce migration risk.
2. Support database conversion to DB/2 from
Oracle or SQL Server.
3. Support limited migration undo.
4. Enhanced Pre-validation before migration.
5. Minimum system downtime (restart target
system after migration, stop event manager
during migration)
1. Support BPM Standard only. Advanced content
is not migrated.
2. DB2 for z/OS databases are not supported.
3. Available as Services Asset only at this point.

3. All historical information is preserved
1. Bringing over all data depending on size and
complexity can increase migration risks which
requires additional testing.
2. Full Downtime required. All applications must be
ready before you can start migrating the system.

Top Practices for Successful Migration
• Minimize Refactoring – we are often tempted to make significant changes
to the applications as part of a migration project. This can lead to un-
intended delay in projects or make it impossible to migrate runtime data.
• Having a comprehensive regression test plan, including non-functional
tests such as stress and performance tests, can help eliminate surprises in
the project.
• Review and playback often and regularly with business and IT stake
holders, this avoids last minute surprises such as user experience
expectation, security concerns, etc.
• Use good quality data for in-flight migration testing (UAT or production
databases). Database from development environment contains a lot of
development “noise” which causes problems
54

Top Practices for Successful Migration
• Test database upgrade using cloned database of production environment,
estimate migration windows and verify the migrated environment
• Carefully test migrated instances for each Application. Some problems can be
revealed only with specific development patterns unique to specific process
application (e.g. serialization changes between TW6 and BPM8 affected event
correlation)
• There is no fixed formula to estimate the time up front as the migration depends
on a number of factors such as number of process instances, tasks, users, groups,
durable subscriptions, tracking groups, size of your data and execution context,
etc.
• Applications should be upgraded and running correctly in target
system at least 2 months before go-live date. Migration and Performance
testing should start as soon as possible, not just a couple weeks before go-
live.
55

Other special considerations
• Account of changes in security model early – want to switch to LDAP
from file-based repository?
• Account for non-standard cluster configuration if you’re not following
the IBM recommended golden topology for your setup.
• BPM + Monitor. If your source BPM environment is augmented with
Monitor in the same cell, but in BPM 8550/8560/8570, we don’t support
BPM and Monitor in the same cell any longer, you have to follow two
separate procedures to migrate BPM and Monitor to separate cells on
BPM 8550/BPM 8560/BPM 8570.
56

Other special considerations
• Test the cases that some instance arrives at an activity that waiting for
some event (UCA), make sure the messages can still be consumed after
migration.
• If you’re migrating from multiple deployment environments, you need to do
the migration procedure for each of your deployment environment.
• Port number maybe changed after migration, you need to update them
manually or use the new ports.
• BPMMigrate command can rerun if it doesn’t import SIB messages yet or
you can clean SIB tables before the second run.
• Backup fileRegistry.xml if you want to enable LDAP after migration, or will
meet with some errors when try to access the document tables.
• We don’t support the migration of IID UTE
57

Other considerations
• SOE & Browser version, e.g. BPM 856 add supports for IE11.
• Test web UI for browser compatibility, esp. any pages with customized CSS, customized
web page with HTML elements, uses 3rd party javascript libraries (e.g. jQuery), or using
browser objects.
• Process Portal: the built-in Portal is updated in 856 but we do not expect any
compatibility issues.
• If moving from BPM 8013, BPM 856 is just an updated portal and we do not expect any
compatibility issues.
• If moving from BPM 751, BPM 856 is an updated portal from BPM 8013 with similar user
experience.
• If you have a customized Portal, and you’re only using documented BPM API, then the
customized Portal should continue to work in BPM 856.
• Heritage Coaches
• There is no major changes to Heritage Coaches from BPM 751x/801x to BPM 8.5.6. We
do not expect any compatibility issues.
58

Other considerations
• Dojo version
• Dojo is an open source standard to build web UI.
• Different BPM versions ship with different Dojo version:
• Dojo 1.6.1 in BPM 7511
• Dojo 1.7.4 in BPM 8013
• Dojo 1.10.3 in BPM 856
• If Dojo is used to build custom web UI, Please refer to release notes to determine if
changes are necessary.
• https://dojotoolkit.org/reference-guide/1.8/releasenotes/1.8.html
59

Other Considerations
• Coach NG (available in BPM 8013) is build using Dojo
• If your applications only uses the built-in Coach Views, we do not expect any compatibility issues.
• If you develop your own custom Coach Views and use dojo:
• If application continues to use 8013 Coach Toolkit, dojo version will remain the same as before and we do
not expect any compatibility issues.
• If applications updates to use 856 Coach Toolkit to take advantages of new features, the dojo version will be
updated from dojo 1.7.4 to dojo 1.10.3.
• As a good practice, minimize your direct dependency on dojo by centralizing all your dojo code to
a small set of “base” Coach Views, and then build more complex Coach Views on top of those.
• Guidance on System toolkit upgrade
• Before making any function enhancements to your applications, make sure your application
works with the old System toolkit
• Once validated, upgrade to the latest System toolkit to take advantages of the updated features.

Types for data for backup
• Installation Data
• Includes the product binaries, ifixes, and profiles
• Backups should be taken after any new of product software has been installed.
• Purpose: Since assuming the fix level is known, the binaries could be re-installed from the product media, the
benefits of this backup are for faster creation of binaries, and assurance that you can restore the exact same set
of binaries.
• Topology Configuration Data
• Includes all configuration done over and above the base creation. Federating nodes, creation of containers,
configuring product base data sources, creating of product related data schemas in databases.
• Purpose: Since all of these actions can be scripted in a fully automated install, the benefits of backup are to
improve the time taken to create the environment, and also to be able to create a genuine replica of the original
cell, including an system generate unique ids associated with it.
• Application Configuration Data
• Includes all deployed applications, and any associated application specific changes made to the environment.
• Purpose: Since all executable deployed to the environment should be stored in version control it should
therefore be possible to re-deploy all applications onto clean topology. There may be some benefit in the
comparative time to restore compared to creation of an environment from scratch and deployment of
applications. There may also be an advantage in diagnosis of issues requiring comparative analysis of the
application versions deployed.
• Runtime Data
• Runtime data is defined as data that represents the current state of interaction occurring in WPS at a given time,
and typically contains the current state of the business data passing through the system. Runtime data exists in
the databases, messaging engine destinations (ultimately backed by a database), and in the transaction logs.
Remember, two phase commit transactions might be taking place in the infrastructure, so anything less then a
synchronised backup will be pointless.
