Hi @AKIKO 

If the QMC is greyed out after the restore most likely reason would be the account used to log in might not have a Root Admin privilege. Is it the same account that is used from the old server to new server?

Hi @Vikram_Jayakumar,

Yes if the QMC is greyed after a restore it mean the account you are using is not RootAdmin in Sense.

If you dont know how to do that I invite to open a case with us.

Also after a restore you need to make the path for the shared has been changed - https://community.qlik.com/t5/Knowledge/How-to-change-the-share-path-in-Qlik-Sense-Service-Cluster/t...
