I'm about to replace my old server. Both servers are on my internal network. The old one ist running debian lenny(32bit) with dovecot 1.0.15 and the new one debian Wheezy with dovecot 2.1.7. I set up the users on both systems identically (same gid uid). My first attempt was tho simply rsync the Maildirs along with the homes. Both deovecot versions are set up with the maildir format, but this results in ~30% doublicated mails on the new server. I then learned about doveadm/dsync, only to figure out that this isn't available in v 1.0.15 and therefor won't work. So which could be the most painless way to solve that?
imapsync is version agnostic and if you have a database with the user-logins it should be easy to geenrate a shellscript
i did migration of around 200000 messages and some hundret users from Apple OSX EIMS to dbmail/dovecot in 2009 this way
sadly, this is not availble from the debian repos. I searched a bit around: syncmaildir, imapsync: only available in in Lenny OR Wheezy, but needed on both servers
needed on both servers is simply not true i have even a template in my admin-backend to generate imapsync scripts out of a db
imapsync --host1 [source] --user1 [user1] --password1 [pwd1] --authmech1 LOGIN --host2 [target] --user2 [user2] --password2 [pwd2] --authmech2 LOGIN --skipsize
