Upgrade major version
This page describes how to upgrade the major version of your PostgreSQL database.
Preparations¶
Before doing a major version upgrade, consult the Google Cloud SQL documentation for any preparation that needs to be done.
Warning
Upgrading requires the instance to become unavailable for a period of time, depending on the size of your database. Expect a downtime of 10 minutes or more.
We recommend that you schedule your upgrade to a time when your application can be offline.
Choose a new major version¶
Select a new major version of PostgreSQL that you want to upgrade to. For safe upgrades, it is recommended to only do one major version at a time.
The full list of supported versions can be found in the application spec reference.
Change the major version¶
To change the major version, modify the type field in your application manifest:
Commit and push the changes to your application repository.
The upgrade will start the next time you deploy your application.
