Migration will be done in the maintenance window of your RDS instance. During this migration, your database may be shutdown and restarted multiple times. If you choose the “Apply Immediately” option, the migration will be initiated immediately after clicking on the “Modify DB Instance” button. If you choose not to apply the change immediately, the migration will be performed during your next maintenance window.
Your PostgreSQL, MySQL, or MariaDB databases in Amazon RDS running on M1, M2, M3, R3, or T1 instances will be automatically migrated to an equivalent M5, R5, or T3 instance by RDS, no earlier than February 6th, 2023 starting 12 AM UTC, as per the migration path.
To avoid any unplanned disruptions, we recommend that you migrate your PostgreSQL, MySQL, and MariaDB databases in Amazon RDS running on M1, M2, M3, R3, or T1 instances to an equivalent M5, R5, or T3 instance before February 3, 2023.
