Bacula 9.4 and 9.6 compatibility...

I need to do a rather complex server upgrade, from debian buster to debian
bookworm (really: from PVE 6 to PVE 8).

Buster have bacula 9.4.2, bullseye and bookworm have 9.6.7.


Looking at bacula 9.6 release notes i catch:

	The catalog datbase format remains unchanged from the 9.4.4 release

(https://www.bacula.org/bacula-release-9-6-3/)


It is possible to have, for a limited amount of time, director and storage
daemons on different 9.4 and 9.6 version, thanks to catalog compatibility?


So, can i upgrade director to 9.6, and smoothly upgrade storages to 9.6, one
by one, still using 9.4 storages?


Thanks.
