Are you planning an upgrade to a newer release of IBM Rational Team Concert (RTC), Rational Quality Manager (RQM), Rational Requirements Composer (RRC), Rational DOORS Next Generation (DNG) or your Jazz Team Server (JTS) and unsure about whether or not your clients or servers need to be upgraded together or can be upgraded separately?
Will your old clients connect to your newly upgraded servers? What about backward compatibility - can you upgrade your clients first? Do your clients and servers need to be on the same release?
The Client and server version compatibility section of the IBM Collaborative Lifecyle Management (CLM) documentation will help you answer those questions and more.
In addition to the information you will find there, further details to help with your upgrade planning can be found in the Installing and upgrading section of the Deployment wiki on jazz.net.
