Frequently asked questions

  • The Standard tier of Database Migration Service supports offline migrations and is free to use.

  • DMS Premium tier is billed on a predictable, hourly rate based on provisioned compute in vCore for your migration service.

    You can use 4 vCore Premium DMS for free for 6 months (183 days) from DMS service creation before billing starts.

    For example:

    • If you use 4 vCore Premium DMS for 6 months (183 days) or less from the time of DMS service creation, you will not be billed (DMS Premium 4 vCore is free for 183 days from DMS service creation). So if you use 4 vCore Premium DMS for 3 months, it will be free.
    • If you create a 4 vCore Premium DMS service on 15th March, your 6-month (183 days) free period will start when you create a DMS service on 15th March and will continue until 14th September. For usage occurring on or after 15th September, you will be billed per hour for the compute resources you provision. If you use 4 vCore Premium DMS from 15th March to 1st November, you will have free usage until 14th September (183 days) and then will be billed for usage from 15th September to 1st November.
  • Once you create a DMS service, you can use DMS for up to 1 year from the date of service creation.

  • Customers can create 2 DMS services per subscription. To create additional services, please create a support ticket.
