The new environment has Java 8 + Weblogic 11c + AEM6 (new AEM deployment).
The old environment runs on Java 8 + Weblogic 11c + AEM6+SP2 (existing AEM deployment).
What we are trying to do is: moving the whole repository (crx-quickstart/repository folder) of the old environment on the new AEM6 installation in the new environment.
