I had a standalone WPS 9.0 environment with WAS 8.5 und JDK 7. (migrated from WPS 8.5.x)
When I migrate the WAS 8.5 to a WAS 9 on the same server I used following IBM paper (https://www.ibm.com/support/knowledgecenter/en/SSHRKX_9.0.0/mp/was/ug_instwas.html).
I also copied the /opt/IBM/WebSphere/Portalserver to /opt/IBM/WebSphere9/Portalserver directory - otherwise the migration scripts did not work.
The new migrated Portal server is up and running on WAS 9 and Java 8.
The problem: The IBM Installation Manager still has the old WPS directory (/opt/IBM/WebSphere/Portalserver) in the configuration. So it's not possible to update Portal CFs on the migrated instance.
Any ideas would be great!
