Comment 2 for bug 1811867

The ceph-mon and ceph-osd charms should be updated to latest stable charm revs before taking on a migration or payload upgrade task. We should make the docs explicit about that.

FWIW, that is the case for all migrations, payload upgrades, series upgrades: we expect all charms to be on the latest stable rev.

Do we need to add further clarity to the procedure, regarding osd count?
