When moving from one version of WebSphere to another that hosts RTC, I would think the simplist option would be to:
0. Stop the existing WebSphere servers
1. Install the newer version of WebSphere
2. Create the profiles / server instances
3. Deploy the RTC applications
4. Update the WebSphere configuration with the required settings / custom properties to point to the existing RTC config
5.  start up the servers

NOTE: I am assuming the existing version of RTC will not be upgraded as well and that the existing CLM war files that were deployed to the previous version of WebSphere will be deployed to the new version of WebSphere.

If RTC will be upgraded as well, then in addition to installing the newer  release of WebSphere, also install the latest version of RTC, go through the steps to update the RTC configuration / DB and deploy the CLM applications to the latest release of WebSphere.

Not that I am aware of on The WebSphere User Group Organization has a great two part walk through on migrating from WAS 7 to 8 including tools methods etc. I have provided the link below. 

Hope this helps. 
Thanks for using the forum!

As a side note. A great took for automating this entire process would be Rational Automation Framework. Customers have gone from 6.1 to 8.5 and 7.0 to 8.0 using this tool. If you have additional questions or concerns regarding RAF. Please check out the twitter.

Hi Milan,
There is some info in the CLM information center:
It is not specific to upgrading but should cover what you need.

Changing WebSphere Application Server installations and instances

Here are some WebSphere technotes on the subject as well.
