Now I think I understand what you are asking.

Currently the queue name is clientid.subname. In the failover situation, if we suffix the name with a number then we should be able to tell them apart

e.g. the failover queue would have name clientid.subname.1.

When unsubscribing we can then identify the queue properly.

Any new connections should only be added to the original queue not the failed over one.

We could put some clever logic in that said something like "if number of messages in queue < 1000 (or whatever)" then merge partial queues, but this is a nice to have.
