Upgrade
Check the installed version with deaconguard version, and read the changelog for what changed; any upgrade steps are listed there. Back up the server's data before upgrading across a minor version, for example from 0.3.x to 0.4.0.
Upgrade the server first, then its agents. An agent from the previous release keeps working with a newer server while you upgrade.
| Installed with | Upgrade |
|---|---|
| Install script | Run curl -fsSL https://get.deaconguard.io | sh - again on the server, then on each agent. On an enrolled agent it upgrades the agent and keeps its enrollment. Set DEACONGUARD_VERSION for a specific release. |
.deb / .rpm | Repeat the manual install steps with the new VERSION. |
| Archive | Repeat the archive steps; they replace /usr/local/bin/deaconguard. |
Upgrading the package restarts the running deaconguard-server and deaconguard-agent services. The new version upgrades the database on its first start; scans that were running are marked as interrupted.
No downgrades
Once a newer version has upgraded the database, an older version cannot open it. To go back, restore the backup you took before the upgrade.
