Upgrade major version

Before doing a major version upgrade, you should check the Cloud SQL docs on upgrading PostgreSQL for an instance for any preparation that needs to be done.

When you are ready, you can change type in your nais.yaml to a new major version of PostgreSQL, and redeploy, and the upgrade will start. For safe upgrades, it is recommended to only do one major version at a time.

Warning

Upgrading requires the instance to become unavailable for a period of time depending on the size of your database (expect 10 minutes or more of downtime). Be sure to schedule your upgrade when your application can be offline.
