I'm using dovecot-2.1.15 with Maildir mailboxes located on an NFS filer. Postfix is used to deliver mail through procmail ("mailbox_command) as LDA.
Our team has bought another filer and everything is meant to go on it, so we're planning to migrate those mailboxes to the new filer. .. I was wondering if such a migration could be done differently in order to be seamless to the user :
for the postfix part, it would be easy, I guess, to create a new service (and a new transport map using this service) to deliver to the new location
but for the imap part, I'm not sure if it can be done. My guess is that, if feasible, it would involve some namespace settings and a dsync copy but I cannot figure out how exactly.
http://wiki2.dovecot.org/Tools/Dsync#example_converting works for moving mailboxes as well as converting. It works even while procmail is used to deliver mails.
