Before Migrating the Application

The Migration tool provides limited support for proprietary APIs and custom JSP tags. The rest of the unsupported API usages show up in the Migration report and need to be manually corrected before you can deploy your application. Therefore, before you start the migration, it is recommended that you run the Application Verification Kit(AVK) to gauge the extent of J2EE compliance of your application.

Before you actually begin the migration process, refer http://java.sun.com/j2ee/tools/migration/doc/prerun.html for information on how to prepare your application for migration.
