This doesn't really work for topics; you need to get the new messages to
collect on b2 while the old consumer drains b1, and only then have the old
consumer disconnect and reconnect on b2; you can't have the consumer
simultaneously connected to both b1 and b2. (Obviously this is only for

Import/export of the stores still won't roll a non-durable topic
subscription from the old to the new broker, which means that when the
consumer disconnects from the old broker it will lose all unconsumed
messages as well as any messages produced between when it disconnects from
the old broker and
note - as part of apollo - there was some tooling around export/import
of message stores.
apollo does import and 5.x does export [1].
I guess it would not be much work to provide a 5.x import tool.
Scheduler store is still an outlier though.

This solution works in certain situations, but there's currently no way to
cleanly migrate consumers to the new broker in all situations. Scheduled
messages and non-durable topic subscriptions are two examples of cases
where simply standing up a new broker and having all clients move to it
isn't r
