Soory for the late reply, I was in PTO.

As brian said, the migration must start with a valid legacy configuration.

In your case, let’s say you start with WildFly 9 configuration. The default resource adapter name in the ejb subsystem is “hornetq-ra” and there is a corresponding pooled-connection-factory with that name in the (legacy) messaging subsystem.

When you migrate the messaging subsystem, a new pooled-connection-factory will be added in the new messaging-activemq subsystem with the same name "hornetq-ra”.
So the RA has changed (from HornetQ to Artemis) but its name is the same and the ejb subsystem will work as expected after migration.
