Xinyu Liu commented on SAMZA-979:
---------------------------------
Right, we do not support migration from 0.9 directly to 0.11. A job (< 0.10)
needs to migrate to 0.10 so that it has the changlog partition map from
checkpoint to the coordinator stream. Then upgrading to 0.11 does not requite
further migration.
> Remove KafkaCheckpointMigration
