My company does a lot of migration... in the other direction. I bleed yellow myself, so every mention of migration projects that I see on our internal mailing lists gives me a bit of a pain -- but business is business. IBM's services groups do Domino to Exhange migrations, too. As a participant in my company's messaging community, I'm not going to challenge the validity of money-making business that meets customers perceived needs, but I certainly can take the opportunity to point out other potential valid money-making opportunities... and that's what I intend to do with the information from this session.
The presenters covered best migration practices, including a discussion of strategies and tools, and they also covered the use of DAMO to counter resistance from Outlook fans. Not a lot of new ground here, really, but having it all down in one place is useful for me. The pros and cons of using the Microsoft connectors versus using SMTP were discussed, and fact that there's no IBM-supported way to do calendar busy-time coexistence stands out to me as a pretty sore thumb. Having to rely on Microsoft tools just doesn't cut it. The vendor that you are migrating to should be the one that you are counting on for coexistence success. That's just common sense.
During Q&A, I asked about what practices were used to deal with PST files and 3rd party archives. I was immediately answered with "I was wondering how long it would take for someone to mention 'the P-word'". The story is pretty much what I expected -- fully manual. They didn't touch on what to do with 3rd-party archive systems; and that's not surprising to me at all, since there are no easy answers. These sorts of things may always have to be dealt with on a case-by-case basis
