Hi Julian,
For migration solution in production I wrote a big Script that, the main steps
(in this mail without error handling):
1.) Copy the complete user account to the new box by rsync (rysnc is faster
than doveadm backup).
2.) Update new destination in a loop (min=2, max=10, retry on error 75):
doveadm backup -u $USER tcp:${NEW_MBOX}:${DADM_PORT}
3.) Change LDAP to new destination and kick user on old box.
4.) Call a latest sync for possible new mails on old box: doveadm sync -1 u
$USER tcp:${NEW_MBOX}:${DADM_PORT}"
The Script has migrate millions of accounts in production. I use "parallel" to
optimize the runtime.
