I am in the planning phase for upgrading one of my CLM environments from 6.0.3 to 6.0.4.

I would like to know if there is a procedure to move from WAS Full Profile to Liberty Profile.

 Here are instructions I found in an InterConnect session held this past March.  The session name was Migrating a Jazz Environment to WebSphere Liberty.


Install Jazz Applications of similar version with Liberty Profile Copy Application Data from existing CLM installation

• Copy <Old_Install_home>\server\conf TO <New_Install_home>\server

Create Liberty Profile server directory structure

• $> server.startup –create

Configure your Liberty Profile to Match WAS Full profile

  • JVM variables - <jazz_home>\server\server.startup.bat(sh)

  • User Registry Configuration

    • server.xml – Which type of User Registry to include, SSO and Certificate Configurations (<jazz_home>/server/liberty/servers/clm)

    • basicUserRegistry.xml – File based registry (<jazz_home>/server/liberty/servers/clm/conf)

    • ldapUserRegistry.xml – LDAP User registry (<jazz_home>/server/liberty/servers/clm/conf)

    • application.xml – Security Role Mappings (<jazz_home>/server/liberty/servers/clm/conf)

It should be quite easy as Liberty works out of the box. If you have absolute paths to the index folders in teamserver.properties files, I don't see any problems with just starting Liberty profile after the migration. If you have multiple profiles, particularly on the same machine, to migrate, it will be a bit more involved, as you need to create multiple Liberty profiles and probably modify the server.startup and server.shutdown scripts as well. Studying the scripts will give you plenty of hints on how to do that.
