You have probably landed here with an email notification received from AWS.

You are not alone!

Yes, AWS is indeed deprecating the M4, R4, or T2 instance types. So you should migrate your instance to the next available series before May 31, 2024

Upgrade Path

Upgrade M4 instance to M5 instance or higher
Upgrade R4 instance to R5 instance or higher
Upgrade T2 instance to T3 instance or higher

If you need any support for this migration, we HAZERCLOUD team is here to help. Our AWS Certified Solution Architect and Security Specialist team will assess your account and upgrade the instance types. We also completely assess your AWS account and secure it as well.

Email Received from AWS

Hello,

You are receiving this notification because we have identified that you have one or more Amazon RDS for MySQL, MariaDB, and PostgreSQL database instances running on M4, R4, and T2 instance types. You can disregard this notification if you are no longer running these database instances or have already upgraded them to new generation instance types.

In June 2023, Amazon RDS announced the deprecation of M4, R4, and T2 database instance types on Amazon RDS for MySQL, MariaDB, and PostgreSQL.

Starting March 11, 2024, Amazon RDS will begin disabling the creation of Amazon RDS for MySQL, MariaDB, and PostgreSQL database instances running on M4, R4, or T2 instance types. And starting on June 1, 2024, Amazon RDS will make best effort to begin upgrading MySQL, MariaDB, and PostgreSQL database instances running on M4, R4, or T2 instance types to equivalent size M5, R5, or T3 newer generation instance type, if available.

We strongly recommend that you migrate your existing Amazon RDS database instances running M4, R4, and T2 instance types to newer generation instance types before May 31, 2024. You may use the following recommendation:

* Upgrade M4 instance to M5 instance or higher
* Upgrade R4 instance to R5 instance or higher
* Upgrade T2 instance to T3 instance or higher

A list of your impacted resource(s) can be found in the 'Affected resources' tab of your AWS Health Dashboard.

How will my Amazon RDS Reserved Instances (RIs) be impacted?

If you upgrade your instance types that are receiving a billing benefit from RIs, the RIs will no longer cover the database instances and you may see additional on-demand charges on your bill. To avoid this, we recommend the following:

* If you have no RIs, or if your RIs have expired, you should migrate your instances at the earliest convenience.
* If you have active RIs which expire before June 1, 2024, you should wait for the RIs to expire and then migrate your instances. You can then purchase new RIs for the upgraded instance types.
* If you have RIs which will be active after May 31, 2024, you should not migrate your instances. RDS will automatically upgrade database instances and RIs that are active after May 31, 2024.

To seamlessly upgrade your database’s instance type or engine version, you may consider using RDS Blue Green Deployments [1] for RDS MySQL and RDS PostgreSQL. If you have any questions or concerns, please reach out to AWS Support [2].
