Update Nuvlo's server software

Step 1 Open Server updates

On Servers, click Manage updates. To update a single server, open it, click the Settings tab and click Check for updates in the Server software row.

Step 2 Check which servers need the update

Click Check for updates. Nuvlo connects to each running server and reads its installed version. The page sorts servers into three groups:

• Updates available: servers behind the latest version shown at the top.
• Already up to date: servers on the latest version.
• Needs attention: servers that are offline or whose version couldn't be read. Click Check version to try a single server again.

Legacy in the Installed column means the server was set up before Nuvlo tracked versions. It can be updated like any other.

Step 3 Select servers

Tick the servers to update, or click Select all. Tick Reboot after updating if you want each server restarted once its update passes the health checks.

Step 4 Start the update

Click the update button in the header, which names the count and version, for example Update 2 servers to Nuvlo followed by the latest version number. The confirmation explains that servers update one at a time and must pass health checks before the next begins. Sites, databases, uploads and volumes are not touched. Click the button in the dialog to start.

Step 5 Follow the progress

Update progress shows each server as Queued, Checking, Updating, Rebooting, Verifying, then Updated. Click Logs next to a server to see its update output.

If a server fails, the rollout stops: it shows Failed and the servers after it show Skipped. Open Logs to see why, fix the cause, and start the update again for the remaining servers.
