The MS Exchange Team has posted an in-depth article on moving public folder replicas from Exchange 2000 to Exchange 2007. A very good article to bookmark.
“In Exchange 2000 we don’t have the ability to right click on the public folder store and choose “move all replicas” as we have in the Exchange 2003 ESM. With “move all replicas” there is just one action needed to add replicas to the new public folder store and remove replicas from the old public folder store. Instead, with Exchange 2000 ESM there are three actions needed:
- Add server to replica list
- Waiting for replication
- Remove server from replica list”
