I am trying upgrade my mariadb galera cluster (10.6.12 + 26.4.14) to 11.4.3 + 26.4.19. I use rolling upgrade method, upgrade one node first and try rejoin the cluster. But the upgraded node failed to join the cluster !! I can not find any document here. Is mariadb with galera cluster upgrade from 10.6 to 11.4 not okey ? [ I am success upgrade from 10.6.12 to 10.11.9, but failed from 10.11.9 to 11.4.3 too. ]
