[keycloak-dev] Hot or Rolling upgrade

[Simon Payne]

Hi, i'm also interested in this as we would ideally like to perform a zero
downtime release.

upgrading each instance will be relatively straightforward if taken out of
the cluster, however i believe the complexity will come if any release
includes breaking changes on either the db or remote cache.

i'm trying to understand this at the moment myself, so will be watching
this with interest.

Simon.
