Feasibility of some BW tools while migrating from 7.0 to 7.5

Hi All,

On of our client is planning to upgrade from BW 7.0 to 7.5. They are currently using the below features in 7.0-

1. BEx Analyzer
2. Report Designer
3. Web Application Designer
4. RDA
5. SEM BCS

I just want to know whether there is any hurdles in migrating these to BW 7.5 ? Is any of these tools are obsolete in 7.5 ? Is there any special case that we should keep in mind for migrating these ?

Appreciate your time and effort, points will be assigned. Kindly provide your inputs.

Thanks

Renju
