Hi @SanthoshDurgam-6782m
In your case if you are using one subscription, your best bet would be to create a new subscription and move the VMs as described here. Resources such as VMs and apps are created under subscriptions, not tenants. Identities are created under tenants.
A subscription can only be associated to one tenant at a time. So you will need to move the VM from the subscription associated with your current tenant to another subscription associated with the other tenant.
You can follow the three-step process described in the article:
Step 1: If dependent resources are distributed across different resource groups, first move them into one resource group.
Step 2: Move the resource and dependent resources together from the source subscription to the target subscription.
Step 3: Optionally, redistribute the dependent resources to different resource groups within the target subscription.
