Usage notes
When you upgrade the database proxy version of your RDS instance, new sessions are connected to the database proxy of the new version to reduce the impacts on your workloads.
Active sessions on the database proxy of the original version are retained for 8 hours. The database proxy of the original version is automatically disconnected within the first maintenance window.
When the database proxy of the original version is disconnected, existing connections on the database proxy are immediately terminated. Make sure that your application is configured to automatically reconnect to your database system.
If you upgrade the database proxy version multiple times within a short period of time, the system retains only the sessions on the database proxy before the most recent upgrade.
We recommend that you perform the upgrade during off-peak hours. Make sure that your application can automatically reconnect to your RDS instance.
Procedure
Go to the Instances page. In the top navigation bar, select the region in which the RDS instance resides. Then, find the RDS instance and click the ID of the instance.
In the left-side navigation pane, click Database Proxy.
In the Basic Information section, click Upgrade to the right of the Proxy Version parameter.
NoteIf the database proxy uses the latest version, the Upgrade button is not displayed.

NoteYou can select Upgrade Now or Upgrade Within Maintenance Window for the Upgrade Time parameter. For more information about the maintenance window, see Configure a maintenance window.
After you set the Upgrade Time parameter to Upgrade Within Maintenance Window and click OK, the RDS instance generates an upgrade plan based on the current maintenance window. If you modify the maintenance window, the upgrade plan that is generated is not affected.
