Upgrades of your on-prem installation
How Yavaren upgrades your on-prem installation, what you approve and when, your maintenance window, following an upgrade stage by stage, and upgrading an air-gapped installation.
Yavaren publishes new releases with their notes. Your installation learns about them over the Cloud Link and shows them on Platform admin › System › Upgrades. Nothing on your installation changes until the support mode you chose allows it.
What happens, by support mode
| Your support mode | What happens |
|---|---|
| Support sessions (the default) | Yavaren sends an upgrade request: the version, the release notes, and a deadline when it is a security release. Your administrators are told by e-mail and see it on the Upgrades page. Choose Upgrade now, or a time that suits you, or postpone it. Until you do, nothing is upgraded. Your approval allows only that release's versions, from the time you chose |
| Full remote management | Yavaren upgrades your installation by itself, but only inside the maintenance window you set on the same page (for example Saturday 02:00 for four hours). Without a window, at any time |
| Air-gapped | No request arrives. Upgrade with the next offline bundle (the installer's upgrade mode), then use Export the upgrade report on the Upgrades page and send the file to Yavaren |
A security release has a date it is due by. You can postpone it up to that date, not past it. As the date comes near, every administrator sees a banner. Even past the date your installation is never upgraded without your approval: Yavaren contacts you instead.
During an upgrade
The Upgrades page shows the upgrade stage by stage: downloading, verifying (the images Yavaren signed), backing up the database, migrating, switching, health check. If the new version does not become healthy, the previous one is put back by itself, and the page says why, with the last lines of the step that failed. The kill switch on Support access stops everything, an upgrade you approved included; an upgrade that had already switched versions is put back.
Your maintenance window
Add one or more weekly slots (days, a start time, how long) in your time zone, and a note for Yavaren if you like. Yavaren staff see your window. It decides when a fully managed installation is upgraded; an upgrade you approve runs at the time you chose instead.
History
Everything Yavaren asked for, who asked, what allowed it (your approval, a support session, or full management) and how it ended is listed on the page and in your audit log.
