Change associated AAD Directory for Azure Subscription to new Tenant

Hi Humans,

I'm following the concept in an article here https://ronnydejong.com/2018/07/24/unleash-your-azure-csp-subscription-for-cloud-management-gateway-deployments/ to associate an existing 'Azure in Open' Azure subscription with a new Azure Active Directory.

The information I can't seem to find is will there be an impact to an existing Recovery Services Vault that exists in my Azure in Open subscription (in the article subscription B) that has an Azure Backup Server attached. I.e. when I reassociate the Azure Subscription B to a new AAD tenant A, will my backup to Azure stop working?

I could always create a new PAYG in Tenant A but I am trying to keep the number of subscriptions at a minimum.

If anyone has completed a similar move successfully where a RSV is involved please reply!

Thanks

Danny
