Hey there micah,
assuming you have your Dovecot set up using virtual users, I would advise you
to use imapsync for that. It does incremental and recursive IMAP transfers from
one mailbox to another (on different servers too). As it doesn't make a file
copy, but let the two dovecot servers talk directly to each other via IMAP, all
your mails with all flags, dates etc. will be preserved on the destination
system exactly like on your source system.
In your case also the indexes will be written on the fast system automatically
by Dovecot 2.2.5 (if configured to do so), so this might do exactly what you
are looking for.
I have myself successfully transferred over 35000 accounts with imapsync (with
very few problems, almost all of them because of corrupt mailboxes or special
character encoding problems occured through former use of weird obsolete mail
clients) and can highly recommend it.
Best regards and good luck,
Megodin
Yes, I can confirm imapsync works fine:
https://github.com/imapsync/imapsync
It doesn't replicate the dovecot IMAP UIDs / POP3 UIDLs though,
since via IMAP-only it can't force the target IMAP server to
use specific UUIDs.
Dovecot's own tool dsync can preserve UUIDs and is therefore
the better choice when migrating to dovecot:
