 Switching over to using `remember-entities-store = eventsourced` will cause an initial migration of data from the `ShardCoordinator`'s journal into separate event journals going forward.

For all other users there is no need to plan a special deployment - the transition to Akka.NET v1.5 sharding will be seamless. It's only the changing of `state-store-mode` settings that requires a restart of the cluster.
