 ## Restore an existing dedicated SQL pool (formerly SQL DW) to a different tenant through PowerShell
-This is similar guidance to restoring an existing dedicated SQL pool, however the below instructions show that [Get-AzSqlDatabase](/powershell/module/az.sql/Get-AzSqlDatabase?toc=/azure/synapse-analytics/sql-data-warehouse/toc.json&bc=/azure/synapse-analytics/sql-data-warehouse/breadcrumb/toc.json) PowerShell cmdlet should be performed in the originating subscription while the [Restore-AzSqlDatabase](/powershell/module/az.sql/restore-azsqldatabase?toc=/azure/synapse-analytics/sql-data-warehouse/toc.json&bc=/azure/synapse-analytics/sql-data-warehouse/breadcrumb/toc.json) PowerShell cmdlet should be performed in the destination subscription.

 The Powershell script for cross tenant restore works the in the same way as cross-subscription restore when the user is given 'GUEST' access to the destination tenant. As a best practice it is advised to also use the destination Tenant ID along with the destination subscription ID.
