Each version of the KACE Systems Management Appliance has a minimum required agent version.
When an environment needs to be upgraded several server (appliance) versions and it is not possible to address the agents outside of the SMA, it will be necessary to carefully consider the exact upgrade path to keep the agents updated enough to communicate with the new server (appliance) version for agent upgrades.
The minimum agent versions are listed in the release notes for each version. This article was created so this information could be reviewed in one location.
Note: NEVER reboot or shut down the SMA during an upgrade. A reboot can cause catastrophic failure and complete loss of all data stored on the SMA. Contact KACE technical support if the SMA appears to be stuck.
Note: Always complete a full backup and offboard from the SMA to a network location prior to any major changes (including an upgrade). Also note that you should unjoin the box from the domain and disable SSO prior to completing or offboarding said backup. The box can be rejoined to the domain and SSO enabled again after the backup is completed and offboarded.
