Assistance Required for Cross-Tenant Resource Migration

Question

Hello Experts,

I hope this message finds you well. I am moving a few resources (like VMs and storage accounts) from Subscription A (associated with Tenant A) to Subscription B (associated with Tenant B). However, I am facing an issue and would appreciate your assistance.

Here are the steps I have taken so far:

1. Created a guest user in Tenant A using my Tenant B email address.
2. Successfully signed in and completed the authorization process.
3. Assigned the necessary permissions to Subscription A.

Despite these steps, I am unable to see Subscription B within Subscription A, which is preventing me from proceeding with the resource migration.

Could you kindly advise on what might be causing this issue or provide guidance on how to resolve it?

Thank you for your support, and I look forward to your prompt response.

Thanks

Shanuka
