Hi
The service currently supports a variety of source/target pairs, or migration scenarios. For a complete listing of the status of each available migration scenario, see the article Status of migration scenarios supported by the Azure Database Migration Service.
Other migration scenarios are in preview and require submitting a nomination via the DMS Preview site. For a complete listing of the scenarios in preview and to sign up to participate in one of these offerings, see the DMS Preview site.
Thanks
