Message: A software version mismatch has been detected between this appliance and ApplianceName. The current running version for this appliance is VersionNumber, while the version reported by ApplianceName is VersionNumber. Due to compatibility reasons no further configuration changes, such as newly enrolled protected nodes, will be available on this appliance until this issue has been resolved. When possible please ensure each appliance is updated to the same version level.
Cause: Each of the onQ Appliances listed is running different software versions. They must be in sync.
Solution: Compare the versions between the onQ Appliances, then resolve the incompatibility by upgrading each onQ Appliance to the same version level. If the documented upgrade process does not support your upgrade path, contact Quorum Support.
