Migrating to OOo is a challenge for any organization, because it goes against a number of long term perceptions by users, who often believe that Microsoft Office - being more expensive - is a better product. Therefore, the migration to OOo is frequently "sold" within enterprises - by the IT department - as a pure cost saving measure, leaving unchanged the user perception that he is using a "cheap" (i.e. inferior) product. The reality is that OOo is a better product than MS Office, especially when you consider security issues. How can we "sell" the concept that you don't migrate just for saving money? OOo is not "cheap", OOo is free, and freedom is always better than any other choice. Users who switch to OOo should be proud of using OOo, and should understand that they are part of a large community. Building on a number of migration stories, the presentation will provide further evidences of the advantages of OOo, and will show several ways of "selling" the concept internally to users of companies who have switched from Microsoft Office to OOo.
