Upgrade JBoss 3.2.8 to JBoss 4.2

[vishalumredkar]

We have an application developed on JBoss 3.2.8 with use of both EJB 2 and EJB 1.1. We want to upgrade the existing JBoss to version 4.2. Please let us know where we can find the relevant documentation on how this can be done.

You may not find a guide which lists down all the steps involved in migrating your application from 3.2.x to 4.2. There's Upgrade guide for moving from 3.2.x to 4.0. You can find it at http://docs.jboss.org/jbossas/upgrade4/html/.
Then there's the wiki at http://www.jboss.com/wiki/Wiki.jsp where you will find some more relevant information. Also, go through the

If at all there's something which is not covered in these pages, then you can always post a specific question in the forums here.
