Since dsync is incompatible between 2.0<->2.1<->2.2 what is the best way to perform this migration?

I was hoping of rsync'ing all Maildirs from the old machine to the new one (including indexes etc etc) and power up Dovecot 2.2.x and see what happens, but is that possible or is there another (and better) way short of installing 2.0.x on the new machine, rsync everything and then upgrade to 2.2.x?

use rsync!

especially because it is fast after the first "hot sync" and you can repeat the sync, look if all is fine and after you are sure config and data are OK

• stop services on both machines
• rsync a last time
• start services on the new machine
• change IP or DNS

well, and since you don't change data on the old one you have a untouched backup there
