How to migrate from Websphere Appliction Server to Liberty on ELM 7.0.2
One answer
I managed to migrate using the following steps during an upgrade to 7.0.2
1) Install the 7.0.2 with liberty and all the apps I needed
2) start the liberty - this generates the CLM liberty server and all configuration files.
3) run the actual jts/setup on the new server. to configure the ldap, smtp and all of that (this could also be done manually but using the setup is really easy), I copied of course the values form the WAS base settings.
4) stop server and if you use RS then delete the 2 folders 702installdir\server\conf\rs\db and 702installdir\server\conf\rs\metadata
5) run your upgrade scripts as usual
