Sorry. I miss understood what drain messages meant. Please disregard my
previous comment about the purge() function.

That's a good point on purging destinations.

Let me clarify my intent.  By "drain messages," I was referring to
processing them off the broker - not deleting them.  If they can safely be
deleted, there's nothing to do really (except clean-up after the old broker
is shutdown, like wiping the KahaDB).

You should have no problem doing an in-place update with the same config files. Some defaults may have changed, and some settings may have changed, so try it and test well. 

Note the old AMQ store was removed in 5.9, IIRC.

I think you might be interested in knowing how to drain messages. I learned
a helpful way to do it via JMX you can call the *purge()* method on the
QueueViewMBean. It should delete all messages in the queue for you. Not
sure if that is available in the version of activemq your using. To get
access to JMX you can use jconsole. Another option could also be to use the
activemq-admin which should let you purge. Here is a helpful link for more
details. Hope it helps:

Hope it helps

The procedure is:

* Shutdown 5.5.1 broker
* Startup 5.9 broker

If the AMQ persistence adapter was being used, then it will be necessary to
migrate to KahaDB or LevelDB.  In that case:

* Drain messages from 5.5.1 broker
* Shutdown 5.5.1 broker
* Startup 5.9 broker

Draining messages is best done by the applications using ActiveMQ, if
feasible.
