Hi Marek,
thank you for your quick response. I understand that you don’t support this setup.
We would also opt for an optional feature to persist non-offline sessions.
I want to suggest two documentation changes to clarify the current situation:
- Section 4.3: User Sessions: "Keycloak provides implementations for basic in-memory,
Infinispan, Relational Databases and MongoDB"
- Section 35.6.6: The third paragraph states: "It's also possible to configure
Infinispan to persist caches, although that would have impacts on performance.”
We do not use offline sessions at the moment. But we intend to use them in the future.
Persisted offlline sessions are migrated correctly when Keyloak is upgraded?
Cheers,
Martin

Are you using offline sessions? If so, you don't need to configure
infinispan store. Keycloak takes care of persisting offline user/client
sessions into it's database and restore them automatically to infinispan
at next startup. We plan to add support for optionally persist
non-offline user/client sessions too to have them "survive" server
restart. But it's not yet supported ATM.
So for now, I suggest you manually delete the file where are infinispan
sessions stored.
