Thanks for your time and patience. I was able to check this internally and got the following updates:
Subscription which has sentinel resource can be moved to another management group but the configuration/functionalities (can't be defined based upon the data connectors, workbooks etc. used ) could break. My recommendation here would be to start the migration on staging/test env do a through testing and then proceed with production.
If you don't have any further queries and the suggestion works as per your business need. Please "Accept the answer (Yes)" and "share your feedback ". This will help us and others in the community as well.
Thanks,
