EBP 2.0 to SRM 5.0 upgrade

Hi Friends,

We are in the process of upgrading EBP 2.0 to SRM 5.0. During this process wat all things will be required e.g. Is knowledge of Web Dynpro for ABAP is required??IF yes then How Much???

Where can I find the differences between the versions 2.0 to 5.0??

Wat all technical things do I need to know for the same???

I'm trying to search some documentation on EBP 2.0 but unable to do so....Can anyone please forward me the same if you have.

Thanks in Advance...
