My company has about 125 people in a bunch of small offices, I was hoping to be able to migrate to 5.0 when it comes out...one branch at a time.
Here is what I was thinking...
- Leave old IMAP system in place
- Create users one by one on Zimbra server. Have zimbra deliver all external & internal mail to the old system. Setup user's IMAP account as an external account in Zimbra, so mail is copied to the new zimbra server.
Is this possible? The main thing I don't know how to do is have Zimbra deliver mail that should be internal to the new system...to the old system.
Any help would be great!
