INTRODUCTION
• Provide insight in the migration and upgrade possibilities for SOA from 11g to 12c (if you
still have SOA 10g we can discuss later  )
• Provide arguments to decide what is the best way for your organization to upgrade to
12c given your starting point
• Discuss migration strategies
• NOT: complete step-by-step tutorial for all upgrade and migration paths
• NOT: upgrade for other Oracle products

MAYBE NOT TOO MUCH RUSH 

14. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
12.1.3 OR 12.2.1 ?
• You may prefer more bundle patches of 12.1.3 (none yet for 12.2)
• Need for new 12.2 features (e.g. IWS Reports, Insight)
• We prefer to go for the latest usually but YMMV

UPGRADE STRATEGIES
15
To reach your goals

16. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
REVOLUTION VERSUS EVOLUTION
10g to 11g: Lots of new features, but also disruptive change
• New architecture by introducing SCA standard
• WebLogic Server instead of OC4J
• Service Bus instead of OESB
• SOA and BPM both new products
11g to 12cR1 to 12cR2: Evolution instead of revolution
• Same architecture (SCA), same container
• Evolution of existing products
16
“a bit painful”
Much easier than a 10g
upgrade!

17. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
UPGRADE STRATEGIES
SOA / BPM 11g to 12c
• In-place upgrade
or
• New env & Redeployment Key questions:
Long running transactions?
Can they be ‘drained down’?
Parallel Run or Big Bang?

18. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
SOA AND BPM SUITE 11G TO 12C
Runtime
• In place domain upgrade and reconfiguration
• No need to redeploy composites after upgrade
• Long running instances resume after upgrade
Design time
• Open 11g projects in JDeveloper 12c
• Import/export Service Bus projects from
Eclipse to JDeveloper 12c
In-place
Upgrade
Side-by-Side

19. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
SOA AND BPM 11G TO 12C | PREREQUISITES
• SOA/BPM Suite 11.1.1.6 (PS5) or 11.1.1.7 (PS6)
• 64 bit JVM
• OPSS to use DB or LDAP based policy store
• Infrastructure Database must be supported Oracle 11g or 12c Database
• 11g and 12c Oracle Homes located on same host but different directories
• OWSM Policy Manager for Service Bus upgrade
19

20. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
SOA AND BPM 11G TO 12C | UNSUPPORTED
• Domain integrated with non-12c products
–Registry (OSR)
–Repository (OER)
–WebCenter including SOA/BPM task UI exposed as Portlets
• Developer deployments
–Admin Server only Domain
–XE database
• SOA/BPM not running on WebLogic Server
• In-place upgrade of BAM

LESSONS LEARNT (1)
• Be very careful of pre-reqs
• BAM is a non-starter (& can't do an in place upgrade if installed in the 11g domain)
• Design of long running processes is very important
– e.g. if you have some intermediate JMS queues that can give more options
• If possible don’t use an in-place upgrade
– More to go wrong
– Rollback is more difficult
• Carefully weigh risks of in-place vs extra effort (& maybe licence cost) of side-by-side
– Most cases favour side-by-side in our experience
• Tuning between 11g & 12c is very different - much easier in 12 (primarily SOA_INFRA
connection pool sizing)

29. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
LESSONS LEARNT (2)
• Test strategy very important
• Training: e.g. consoles have changed, auto purge, error hospital, new features like that
thingy that needs ESS (fault notification hospital), flow ID
• WLST diff in 12.2 - e.g. deployment scripts => don't focus on design time alone, make
sure look at runtime
• Deployment if using Maven has changed a lot
• Leverage automation scripts to re-create wls configurations (DS, JMS, etc) on side-by-
side
• Eclipse->JDev for OSB - DVMs in OSB, templates (do new analysis) - reason to do side-
by-side (might as well improve prov).
• Assume you will have to open projects in 12c & redeploy (also cleaner)
• Don't wait! probably go to 12.2 but depends on testing31

SUMMARY
32

31. Copyright © 2014, eProseed and/or its affiliates. All rights reserved. | Confidential
SUMMARY
• Going from SOA and BPM 11g to 12c is upgrade instead of migration
• Consider going straight from 11g to 12cR2
• Carefully consider your upgrade approach
• As ever careful testing is very important – especially if doing in-place upgrade
• Training to use 12c enhancements
• Don’t put it off – benefit from the new features you’ve already paid for
