Are you migrating to WildFly or JBoss EAP (JBoss AS is really old, I don't assume you're migrating to this one)? If you're migrating to WildFly then everything is completely free. You'll only get community support and no patches.
If you want commercial support or patches then you need JBoss EAP. This forum is only about WildFly. If you have any licensing questions about JBoss EAP I suggest you get in contact with your Red Hat sales representative.
Thanks for your response..
