I have a client who is at 
Rational Team Concert 4.0.6
Operating System: Red Hat Enterprise Server 5.1.
They are currently on WAS 8.5.0.

They will be upgrading from 4.0.6 to 5.0

It is required that they move to Red Hat Enterprise Server 6.0 as it is the minimum requirement for CLM 5.0. 
As well as upgrade from WAS 8.5.0. to the minimum of

What is the best way to migrate?

Do they migrate CLM 4.0.6 to Red Hat 6.0 on new servers first or should the do a fresh install on CLM 5.0 to Red Hat 6.0 and then point the Oracle database to CLM 5.0? 

What is the best method?

 It depends on how cautious your client is. Since CLM 5.0 supports RHEL 6, we've tested on that and doing the fresh CLM 5.0 install on that should be fine. And of course, you should do some testing on the upgraded server before making it fully available.

But some clients have more robust requirements, where every new software version of all products must be validated separately. If that's the case, you'll probably want to upgrade to RHEL 6 first so that can be validated with server tests. Then upgrade CLM and validate that.
