Hi
I have a migration from Grouwise to Exchange a some years ago.
Now the Exchange is different, but i think the complement to migrate is the same
I remember that my font to learn how to was the
http://www.msexchange.org site.
And the user the Quest tool to handle the migration, very power tool. But this was i think Groupwise 5 and Exchange 2003
Reading the quest site i see that they have now for the Exchange 2007.
http://www.quest.com/groupwise-migrator-for-exchange/features-benefits.aspxOr other tool by nucleus
http://www.nucleustechnologies.com/migrate-groupwise-to-exchange.htmlSo if you want to use the tool, is faster, is safe, and reduce time to do the migration. But of course we need to by this tool. And you may not have the budged.
Take a look to the article from the msexchange site. Is an article with 7 parts, but i think is a complete how to.
http://www.msexchange.org/articles_tutorials/exchange-server-2007/migration-deployment/groupwise-exchange-2007-migration-common-q-a.htmlThis a difficult job, so you need to read all about how to.
If you have the possibility to test this in an test lab, i recommend. I have this first, have some tests, then i pass to the production.
Hope this can help you a bit
