This topic describes how to upgrade the dedicated proxy version of an ApsaraDB RDS for MySQL instance.


The upgrade causes a restart of the dedicated proxy instance, and the restart causes a 30-second transient connection error. The time when the dedicated proxy instance restarts varies based on the specified Upgrade Time. You can select Upgrade Immediate or Upgrade within maintenance period. We recommend that you perform the upgrade during off-peak hours. Otherwise, make sure that your application is configured to automatically reconnect to your database system.


  1. Go to the Database Proxy page.
    1. Log on to the ApsaraDB for RDS console. In the left-side navigation pane, click Instances. In the top navigation bar, select the region where your RDS instance resides.
    2. Find your RDS instance and click its ID. In the left-side navigation pane, click Database Proxy.
  2. Click Upgrade Dedicated Proxy Version.
  3. In the dialog box that appears, set the Upgrade Time parameter and click OK.
