Is there any commonality to the server? use smart groups which have rules to automatically assign the group.

Hi Yogesh,

another option below:

you can use this qscript - make sure the target client group exists beforehand.

https://documentation.commvault.com/2023e/expert/SetClientGroup.html

The SetClientGroup script allows you to add/remove a client from a client group. This script is useful when you want to add/remove multiple clients to the same client group at a given time.
