Migrating from/to Zimbra
I currently have a Zimbra 4.5 server up and running. I'm looking to do a fresh install of ZCS 5 and migrating that data rather than doing an upgrade. I've poked around and haven't been able to find any information on doing something along these lines, though I'm sure it can't be all that uncommon. Does anybody have any information they can point me to regarding procedures for this type of migration?
Hmm... I think you will see that most of the information you find on the forums regarding migrating to another server involves doing a backup on the "old" server and then restoring on the "new" server.
The only thing I can think of off the top of my head is to use 'imapsync' to migrate the data from one server to the other; or setup two accounts in Thunderbird, or some other IMAP client, and then copy/paste messages from one to the other. Of course both of these are somewhat manually processes, especially the copy/paste method, so if you have a lot of accounts it probably won't do.
