Announcement: End of Support of Oracle Instances running on M4 and R4 instances

Amazon RDS M4/R4 instances will enter End of Support for your Oracle databases from March 27, 2023.

We will replace all existing M4/R4 instances with better performing R5/M5 instances which will improve performance at the same cost as existing M4/R4 instances.

All Oracle databases running in Amazon RDS on Commercial M4/R4 instances will be automatically upgraded to the equivalent M5/R5 instance by RDS, no earlier than March 27th starting 12 AM UTC. Automatic migration will be done in the maintenance window of your RDS instance. To avoid any unplanned disruptions, we recommend that you upgrade your instance in Amazon RDS running on M4/R4 before March 27, 2023. The last date for no-creates is January 17th, 2023.

To learn more about the latest instance types supported on RDS, refer to the Amazon RDS user guide [1]. For guidance on modifying your instance class, see the Amazon RDS User Guide [2]. If you have any questions or concerns, the AWS Support Team is available via re:Post [3] and via AWS Premium Support [4].
