Updates and renewals

Your licence includes one year of updates and support from the date you buy. During that year you can install every release we publish. After it ends, your server and agents keep working on the version they have.

Which releases you can install

A release is yours to install if it was published on or before your updates-until date. Your account at account.cvntechnologies.com shows that date on each licence.

• Releases published inside your update year: install them any time, including after the year ends.
• Releases published after your update year: listed, but marked "updates expired on (date), renew". They do not install until you renew.

Update the server

1. In the global admin portal, open Updates.
2. The page checks your account and lists the releases you can install.
3. Choose a release and start the update.

The updater then:

1. downloads the release,
2. verifies its signature, and refuses a release that fails the check,
3. backs up the server's database and configuration,
4. applies the release and runs the database migrations,
5. runs a health check, and rolls back to the backup if the check fails.

Turn on Maintenance mode first if you want backups paused during the update. See Server settings and maintenance.

Agents update themselves

Each release of the server carries matching agent builds. You do not update agents one by one:

1. Every agent asks your server for the current agent version when it connects and every six hours after.
2. If the server has a newer build, the agent downloads it, checks its SHA-256 hash and our Ed25519 release signature, swaps it in and restarts. Your server delivers the build but does not sign it, and a build that fails the check is not installed.
3. The Windows desktop app is updated the same way and offers a restart when the update finished in the background.

To push an update to a device now, use Update in the tenant admin Remote Engine, or run cvn-agent update on the device. Agents that are offline update the next time they connect.

Renewing

Renew from your account at account.cvntechnologies.com. A renewal adds one year of updates and support:

• If your update year has not ended, the new year starts at your current updates-until date, so you lose no days.
• If it has already ended, the new year starts on the day you renew.

Renewing is optional. Nothing stops working if you never renew. You keep the version you have, and you can still read your old support tickets. Opening a new support ticket needs an active update year.
