Miroslav Novak commented on WFLY-5453:
--------------------------------------

Yes, after adding <slave/> there is no NPE during backup activation but I see problem conflicting(same) server-id for invm acceptor of starting backup:

Live and collocated backup has same server-id for in-vm acceptor. Is it possible to change server-id of in-vm acceptor of collocated backup to value different from live in automatic way?
