Create a project in a specific region
In the portal, you can select the geography in which you want to create the project. If you want to create the project within a specific Azure region, using the following API command to create the project.
PUT /subscriptions/<subid>/resourceGroups/<rg>/providers/Microsoft.Migrate/MigrateProjects/<mymigrateprojectname>?api-version=2018-09-01-preview "{location: 'centralus', properties: {}}"
