Hi
After
http://retrospekt.dk/2011/08/migrating-maildir-to-dovecot-2-0-dbox/ I
used a two phases process.
The first, transfering over the network, is done by this shell function,
on the *new* server. The argument is the <user>
fetchOldServer () {
rsync -poazuHK --exclude="**/dovecot.index*" \
-e ssh root@oldServer:/var/mail/Maildirs/$1 /var/mail/oldServer/
}
I had to add --exclude="**/dovecot.index*" because of a change of
endianness (ppc -> amd64).
the second, having dovecot import the folder, is done by this second
fonction
dsync () {
doveadm backup -R -u $1...@mondomaine.fr
maildir:/var/mail/oldServer/$1
}
this one is really fast.
Both in one function
doveImport() { fetchOldServer $1 && dsync $1 }
I tried for initial load to empty mailbox. I am not sure it will works
on a non empty mailbox. But would be nice, as it would allow a fast last
minute sync before switch, minimizing downtime.
