[Dovecot] Migrating domain using IMAPc

[Gedalya]

Some more details?

Is the destination not empty?
As far as I know you should use backup -R to pull from a source to an 
empty destination, and import for "merging" messages into an existing, 
populated mailbox (in which case messages will have new UIDs).

Get us some more details on your situation.
