Upgrade database operators

Starting with Percona Everest 1.2.0, the intuitive UI allows you to upgrade all the database operators and their components in any namespace with a single click.

Before you upgrade

Note

We recommend that you take a database backup before starting the upgrade process.

Before upgrading a database operator, Everest presents a list of tasks that need to be completed to smoothly transition your clusters to the next version of the database operators. These tasks may include:

• Upgrading your database engine version from an unsupported or end-of-life (EOL) version.

• Ensuring your clusters are using a supported Custom Resource (CR) version.
