How to upgrade without loosing current sessions?

Getting advice
1

Hello,

I am currently using keycloak 4.5.0 with 2 nodes. I know sessions are stored in infinispan cache and distributed across the cluster with jgroups.

I would like to upgrade to keycloak 8.0.1 but the jgroups version in 4.5.0 and 8.0.1 are not compatible, so I have this error packet has different version (4.0.11) from ours (4.1.4) and the sessions are not replicated from one old instance to a new one.

Is there something existing to allow to upgrade keycloak without loosing currently opened sessions ?

Thanks

Hello,

Inspired by https://github.com/jgroups-extras/RollingUpgrades
I tried an implementation with Keycloak :https://github.com/jermarchand/RollingUpgrades/blob/master/keycloak.adoc

I don’t have time to continue, but I think it could be the solution.
