Clearing WAS "temp" after upgrading TC

I had TC Beta1 Update1 installed on a Linux Machine with WAS and DB2.
I'm upgrading to TC Beta2. The notes for "Installing Jazz into WebSphere
Application Server" suggest the old bundles need to be cleared out. I
have a jazz.war in the following locations under WebSphere:

../AppServer/profiles/Jazz/installedApps/JazzCell/Jazz.ear/jazz.war
../AppServer/profiles/Jazz/temp/JazzNode/server1/Jazz/jazz.war
../AppServer/profiles/Jazz/wstemp/-1663941914/workspace/cells/JazzCell/applications/Jazz.ear/deployments/Jazz/jazz.war
../AppServer/profiles/Jazz/config/cells/JazzCell/applications/Jazz.ear/deployments/Jazz/jazz.war
../AppServer/profiles/Jazz/config/temp/download/cells/JazzCell/applications/Jazz.ear/deployments/Jazz/jazz.war

Which of these need to be cleared?

Thanks, Brian
