Azure VMs migration from one tenant to another

Question

Hi Community,

I have a task to move/migrate Azure VMs from subscription on one Azure tenant to subscription on another Azure tenant. Moving the subscription is not an option. I think I can treat the VMs as "Physical or other" and use Azure Migrate with an appliance. Is there any another way? Can I treat is as Hyper-V to Azure Migration? Will I need an appliance server for discovery and replication?

The Azure Resources like VMs are always associated with a subscription. So basically you need to move your VMs from one subscription in Tenant A to a subscription in Tenant B.

Now If you want to migrate one VM, in Tenant A, you can use Azure Storage Explorer (https://azure.microsoft.com/en-us/products/storage/storage-explorer/#overview) and Copy the Disk for the VM from Tenant A and paste it to Tenant B. You need to repeat this for each disk associated with your VM. Once the new disks are created you can create a new VM in Tenant B by attaching the disks that you already pasted in Tenant B.

Refer: https://www.remotelyrmm.com/blog/how-to-migrate-an-azure-virtual-machine-from-one-tenant-to-another

If you have one or two VMs, you can follow the above method.

But in case you have many resources follow the below steps.

1. Create subscription in Tenant A (This subscription is for migration purpose) and move all your resources that needs to be moved to this subscription. Refer: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/move-resource-group-and-subscription
2. Once you moved all your resources to a subscription in Tenant A, then move that subscription to Tenant B. Refer: https://learn.microsoft.com/en-us/azure/role-based-access-control/transfer-subscription

Hope this helps
