Unable to Migrate to New Fabric Tenant Due to Power BI Gateway Single-Tenant Limitation

DeepthiSaranya — Wed, 21 Jan 2026 06:41:25 GMT

Problem statement:

The current migration is blocked due to a critical technical constraint.The existing production PowerBI reports are hosted in the old tenant, as the source database resides under the same account.These production reports rely on a single on-premises PowerBI gateway to fetch data from the database.

Due to a gateway and tenant limitation, the same gateway cannot simultaneously serve two different tenants. As a result, migrating data or reporting workloads to the new Fabric environment would break the existing production PowerBI reports. This creates a high risk of production disruption and prevents from proceeding with the migration.

Expectation : We need to connect the database in the new Fabric tenant for migrating the data using the sql credentials without the blocker

Power BI gateways are both machine-bound and tenant-bound, so Microsoft doesn’t support running two Enterprise gateways on the same Windows machine. Have you considered a second VM, if not maybe you can try doing as below.
For zero-downtime migration, you could spin up a small second VM and install a gateway there for the new tenant.
Both gateways can point to the same SQL database — old production keeps running, and the new Fabric tenant can migrate and test. Once you cut over, the old VM can be removed, so the extra cost is only temporary.

Most likely your data sources will move to the new tenant as well.

"migration" is a myth. In the real world you recreate your setup in the new tenant, and then at some point communicate the new URLs to your users.
