Using Migration Tool

If you have an existing J2EE application that runs on another vendor’s application server, you can use the Sun Java System Standard and Enterprise Edition 7 Migration Tool to migrate the application and run it on the 2004Q2 Update 7 release. The migrated application will run on the Sun Java System Standard and Enterprise Edition 7 Application Server 2004Q2 release without any modifications. However, to use the high availability features, change the DTD version of the sun-ejb-jar.xml deployment descriptors to point to sun-ejb-jar_2_0-1.dtd instead of sun-ejb-jar_2_0-0.dtd.
