I think the timers are saved but the correctness of restored timers is not validated, is it? With "normal" window operator, incorrectly restored timer might lead to window not firing or just an exception. > I have modified the ChangelogMigrationRestoreTarget#getRestoredKeyedStateBackend because pq states do not supports migration currently. Could you explain what do you mean, why pq states don't support migration? > BTW, I also enable switching case in ChangelogCompatibilityITCase which uses windows in the graph.
