ClearQuest and ClearCase compatible versions

Hello,

I am trying to determine the correct versions of RQM, CQ and CC I need in an integrated environment.

Right now I have CC and CQ 7.1.0 and RQM Standard 2.0.0.1
They are not currently integrated.

For architecture support reasons I have to upgrade to CC 7.1.1.

I also need to integrate CC and CQ for UCM and setup the CQ Bridge to RQM.

I read that you need RTC 2.0.0.2 for CQ 7.1.1

So is there any guidance of the levels I need to be at for each of tools?
Or should I say at a minium.

Thanks
Steve
