Hello @Jithin M V ,
Thanks for reaching out to Microsoft QnA. Happy to answer your question.
Yes, you are correct, Ubuntu 20.04 is not supported for moving across regions using Azure Resource Mover as mentioned here.
You can also move VMs from one region to another using Azure Site Recovery. However, there are some prerequisites to it. In your case, as you want to move the VM West Europe to South India, it will not be possible as per the region support.
Hope this helps. If you have further queries, please feel free to respond back and tag me in your reply. Thank You.
