How to Migrate Complete Resource Group from One Tenant to Another

Hello @Rohit Kumar - Welcome to Microsoft Q&A community forum. I apologize for the delayed response!

Resource Mover helps you to move Azure resources between Azure regions.

Using Resource Mover, you can currently move the following resources across regions:

• Azure VMs and associated disks
• Encrypted Azure VMs and associated disks. This includes VMs with Azure disk encryption enabled, and Azure VMs using default server-side encryption (both with platform-managed keys and customer-managed keys)
• NICs
• Availability sets
• Azure virtual networks
• Public IP addresses
• Network security groups (NSGs)
• Internal and public load balancers
• Azure SQL databases and elastic pools

That said, Azure resource mover doesn't support moving resource group from one tenant to another.

Refer to Azure resource mover common questions - https://video2.skills-academy.com/bs-latn-ba/azure/resource-mover/common-questions#what-does-it-mean-to-move-a-resource-group

For moving resources from one subscription to another, both subscriptions needs to be in the same tenant. For your scenario (moving resources from one tenant to another) you need to create a new subscription in tenant 1, move resources from subscription 1 to new subscription and then as a final step, change the tenant for a new subscription to tenant 2. The whole process is documented here - https://social.technet.microsoft.com/wiki/contents/articles/51360.azure-how-to-move-resources-between-subscriptions-under-different-tenants.aspx

Hope this helps!
