UM is the Windows install and PM was the ISO upgrade for the vSphere OVA. The previous versions were 6.3 and 2.0.0 respectively. I disabled the pre-existing integration on PM (partial in the new parlance) prior to running the upgrade. From the PM maintenance console, the main menu indicates "no integration enabled" for UM.
We will need logs to troubleshoot further. Please open a case with NetApp Support. If you can generate an ASUP (UI) from both OPM and UM and also capture a Support Bundle (maintenance console) fromboth UM and OPM and upload to the case after it is created, the troubleshoooting time will be minimized. Thanks.
