Should be possible, yeah. I haven't tried this myself, so beware, test carefully, be prepared for possible bumps in the road etc. But you should be able to: 1) Remove the server/all/deploy-hasingleton/jms folder 2) Replace the contents of server/all/deploy/jms with those from server/default/deploy/jms The key thing here, is the JMS server is no longer a singleton -- each AS instance is running a JMS server. That means you need to configure them so they aren't all trying to persist to the same place in your DB. Each needs to write to a separate catalog (in a shared db) or each to its own db.
