If preserving flags and labels is important - it usually is - using
imapsync or similar tools is the only way.
mailbox2dbmail is a 'raw' import-tool that will import messages from
existing mailboxes into dbmail mailboxes. It is not what you want.
With imapsync you can copy email accounts from one IMAP server to
another, and it will do so incrementally so you can run it again and
again and it will only pick up changes and not try to do everything all
over again.
There is one very tricky part when using such a tool: it needs to have
access to the imap account. This implies it needs the passwords for the
accounts on *both* sides.
One tactic I use is:
for each account:
preserve the password on both sides
set the password to a known value on both sides
run imapsync for account
restore the original password on both sides
Of course, preserving the current password depends on the existing
setup. Sometimes this means extracting the encrypted secret from LDAP or
AD, sometimes from /etc/shadow, or from some other authentication
backend provisioned through PAM, ymmv.
For a shadow file I would do:
cp /etc/shadow /etc/shadow.orig
#generate a sha512 salted hash:
HASH=`mysql -N -B -e "select encrypt('somesecret','$6$saltvalue$')"`
#set a new password:
usermod -p "$HASH" username
and once you're done, copy /etc/shadow.orig back to /etc/shadow.
