Amazon RDS for SQL Server is ending support for M4, R4, and T2 Database Instances on March 29, 2024

Amazon RDS for SQL Server is ending support for M4, R4, and T2 Database Instances on March 29, 2024. We strongly recommend that you migrate your existing M4, R4 and T2 instances to the newer generation instance types before March 29, 2024 . You may use the following recommendations to choose a newer generation instance type:

• For M4 instance, we recommend migrating to M5 instance
• For R4 instance, we recommend migrating to R5 instance
• For T2 instance, we recommend migrating to T3 instance

Starting on January 29 2024, we will begin disabling the creation of new Amazon RDS for SQL Server database instances using M4,R4,T2 instance families. We strongly recommend you migrate any of your existing impacted instances to the newer generation instance types before March 20 2024.

In some cases, migrating to a new instance type may result in an increase in cost. If you have Reserved Instances (RI) affected by this notice, you will be able to cancel them after you create new RIs for the same value or higher [1]. If you choose to cancel and re-purchase the instances, you can submit a request to AWS Support [2].

Starting on March 29, 2024, all Amazon RDS for SQL Server M4, R4 and T2 instances that have not been upgraded will be automatically migrated to a newer generation instance of similar size, depending on availability and supportability of those instances in the corresponding regions. This activity will be performed during your maintenance window and your instance will experience downtime.

If you have any questions or concerns, please reach out to AWS Support [2].
