Hi Abhijit, Currently i am working on similar kind of application migration. Can you please let me know what sort of information do i need to collect before the migration. Also let me know if you have any doc's prepared or any other kind of information which will be useful for me in doing the migration. I am new to this migration and ejb related concepts. Please shed me some light on where i can i get information regarding the migration. It will be precise if i am instructed on how to go with the migration. Regards Sekar
