How to upgrade
Since the upgrade to the latest version involves running migration scripts in the database, it is essential to backup the PostgreSQL database before upgrading to the latest version.
Back up
Follow the PostgreSQL charm documentation to back up the database.
Upgrade to the latest version
Upgrade the charm to the latest version:
juju refresh httprequest-lego-provider --revision=<revision number>
You should see the httprequest-lego-provider charm go to Active and Idle state after upgrading.
