Having an issue migrating mailboxes with the doveadm backup tool...
Hey all.
We've got some users that live on our primary email server (which lives in our internal network) that we need to migrate to a second email server (which lives in our DMZ). Both servers serve our domain, example.com, but our first email server runs UW-IMAP, while our newer second server is running dovecot.
We need to get these users cleanly migrated over, with all of their emails, and we're trying to do so with the doveadm backup tool - figuring that it will probably "do" Dovecot better than a generic IMAP to IMAP tool. So far, no dice - we get the following error message:
Jul 13 16:00:00 doveadm(user@example.com): Fatal: All your
namespaces have a location setting. Only namespaces with empty
location settings are converted. (One namespace should default to
mail_location setting)Here is the command I'm trying to run:
