AWS Windows Migration Accelerator

Save costs with AWS Promotional Credits when you accelerate migrations of Windows workloads to AWS.

With customers running Microsoft workloads on AWS for more than 12 years, we have the most experience with Microsoft applications in the cloud and can deliver performance, security, reliability, and cost savings.

AWS Windows Migration Accelerator helps reduce the cost of your migration when you accelerate the migration of Windows servers using AWS Application Migration Service (AWS MGN).

Until December 31, 2024, customers using Application Migration Service to migrate at least 40 servers to AWS in one month — including a minimum of 15 Windows servers — may be eligible to receive a $200 AWS Promotional Credit per Windows server.

If you migrate more than 80 servers — including at least 25 Windows servers — in a calendar month, we will increase the discount to $250 AWS Promotional Credit for each Windows server you migrate to AWS using AWS Application Migration Service.

Migrated servers must be migrated from locations outside of AWS and continuously run on AWS for at least four weeks after migration.

Frequently Asked Questions

Will the servers I have migrated with other AWS services (other than AWS Application Migration Service) be counted towards this program?
No, only servers migrated with Application Migration Service will be counted for this program. 

Will my Linux servers qualify for this program?
Credits are only for Windows servers. However, migrating Linux servers will count in order to qualify for the program (see example below).

How do I sign up?
No sign up is required. Your AWS account automatically qualifies when you meet the program terms per calendar month using AWS Application Migration Service. You will need to send a request to receive credits to The program resets monthly, and credits will be paid only for calendar months where the program terms were met. 

When do I get the credits?
Credits will be calculated and paid upon completion of the program at the end of the term. 

I have several AWS accounts that I use for migration. Can I combine the accounts to qualify for this promotion?
Even though the program pertains to single AWS accounts based on the account ID, you might be able to combine eligibility across multiple account IDs. Please email with your account IDs for consideration. 

Can you give me a few examples of how this program works?

1. A customer migrates 30 servers in a calendar month: no credits are provided, as the customer did not meet the minimum requirements of 40 servers per month.

2. A customer migrates 41 servers in a calendar month, of which 27 are Windows servers: This meets the minimum qualification threshold of 40 servers including at least 15 Windows servers. The 27 Windows servers will qualify for credits. Credits are not paid for migrated Linux servers with this program.
