So, I've done some searching - but search terms are hard to come by, that work, for this query.
In short, migrating a RHEL 5.9 server running the back-ported Dovecot 1.0.7 To: Ububtu 12.04 with 2.0.19, I believe. [I'm not against compiling a more recent version if there's some real advantage to doing so. But I'd certainly prefer to stay with the packaged version.] Most users are POP3, with some leaving messages on the server for a while. Other users are IMAP - whole mail repository on server. --- In an ideal world, I'd like to simply copy all the mailboxes/dirs from one server to the other. [Local/LAN file copies are possible] It would be great if the message ID's wouldn't change, so the read/unread/new etc status all all the messages wouldn't change between the two servers for POP/IMAP. --- So, does anyone have a reasonable walk-through for doing so? Is this a poor idea? Should I simply set myself on fire now and save everyone a lot of hassle? :) Would you suggest an alternative, and tell me if it might achieve the objectives above? I'm more than glad to take pointers to threads on this topic. I just haven't been able to dredge this up with my Google-foo. TIA -Greg
