We've got ZCS 6.0.7 first patch running and seem to be having some trouble moving mailboxes from one server to another. For small mailboxes (300 MB and under), we can easily use the command zmmailboxmove -a firstname.lastname@example.org -s source.server.com -t target.server.com
but for anything larger, this error is returned: Error occurred: Read timed out
Nothing of note appears anywhere in mailbox.log (no exception, no indication of the last event before the read time out).
For somewhat small accounts, the move results in a read timeout and the account data appears to be transfered properly. Testing with slightly larger accounts, the timeout occurs, the account becomes locked in maintenance mode, etc.
