Testing Cross-Tenant Access After Power BI Tenant Migration
Yes, this setup is supported but since [email protected] is now a different identity from [email protected], you’ll need to treat them as a new B2B guest in the original (Infy) tenant. Any existing permissions from the old ID won’t carry over, so content like workspaces or apps must be re-shared with the new guest account.
To validate access: make sure the user is added in Azure AD as UserType = Guest, then have them log in with their Tata credentials. Confirm they can open the shared content and that RLS or CLS works as expected.
Also ensure they're covered under Power BI licensing either through Premium capacity or an assigned license.
It seems like you are talking about 2 different scenarios in your thread : Cross Tenant access and Tenant Migration which are not the same espacially when using Shared capacity.
For Cross-Tenant Access it is like you are inviting an external user to your tenant with limited functionalities eventthough the same organization owns the 2 tenants

On the other hand the Tenant Migration is like you are creating a new Tenant from scratch : Create the Workspace, then download the datasets and reports from the old tenant to upload them into the new tenant and finally add users with their new UID(emails).
Thanks for the clarification.
a. We are working on a full tenant migration. (Infy tenant has Premium capacity, Tata tenant is currently on Shared but will move to Premium next month.)
b. The B2B guest testing is specifically to validate cross-tenant access for a user who has already been migrated to the Tata tenant.Thanks,
