How to migrate EJB 2.1 Project from Websphere 7 to Websphere 8

Question

I have an EJB 2.1 project, works on WebShere 7. I must migrate it to WebSphere 8. Which one is the better (less effort) approach:

1. First convert the project into an EJB3.1 project then migrate into Websphere. If yes, is it easy to do that by a large project?
2. Adapt the project till it works on Websphere8 (What should be taken into account)

Thanks??

Answer 1

The easiest approach is to do nothing: WebSphere Application Server v8 supports EJB 2.1 just as well as v7. Why risk changing something that isn't broken?
