Hello Viet, Welcome to MS Q&A
To recover a subscription that was moved to a new tenant to which you don't have access, you will need to contact the administrator of the new tenant. Here are the steps you can follow:
- Identify the New Tenant Administrator: Determine who the administrator of the new tenant is. This could be someone within your organization or an external party if the subscription was transferred outside your organization.
- Request Access: Contact the administrator of the new tenant and request access to the subscription. You may need to provide details about the subscription and the reason for your access request.
- Transfer Back: If you need the subscription to be moved back to the original tenant, request the administrator to initiate the transfer process back to your tenant.
- Azure Support: If you are unable to contact the new tenant administrator or if there are complications, you can reach out to Azure Support for assistance through azure portal
