Hi SJ.
We are adding this application server to our upgraded QA in the parallel landscape. I wanted to know since we split ABAP and JAVA instance and did release upgrade for ABAP stack, do I have to do anything additional for DI before I use the new version using SWPM? Looks like I can add an additional instance on this app or should I uninstall the lower version first and then install the new version?
Yes, You have to either uninstall the Old App server or Reinstall the OS and install the new upgraded ABAP Application server on QA system, using the new version of SWPM.
