Below snapshot shows the step that I followed for SR upgrading a single box server environment. Same steps can be followed on multiple box environment also, QV installation program will automatically detect the services installed and upgrade that alone.
Note: Upgraded from QV 11.2 SR 5 to QV 11.2 SR 7
I didn’t add description since I felt it is self explanatory.
For any clarifications pls. feel free to post your question as comments I will reply asap.
