[keycloak-user] Upgrading Keycloak 3.4.2 to 4.1.0 in docker

[Erlend Hamnaberg]

Hello all.

I was wondering if it required to run the upgrade steps (apart from the
database migrations and themes ) when deploying keycloak in dockerized form?
I am of course extending

FROM jboss/keycloak:4.1.0.Final

I started the server with just upgrading the database automatically, and it
seems to work fine.
Am I missing something other important step?
