Hi,

I have a setup with 3 Dovecot Director v2.2.36 and director_consistent_hashing = yes ;-)

Now I would like to upgrade to 2.3.7, first only Director and after also Backend.

Can works fine a ring of director with mixed 2.2 and 2.3 version?

Mi idea is to setup a new Director server with 2.3, stop one server with 2.2 and insert the new 2.3 in the current ring to check if works fine.

If all works fine I will replace all Director 2.2 with 2.3 version.

There's no known reason why it wouldn't work. But be prepared in case there is an unknown reason.
