Brian,
I guess I wasn't clear.
If I pull down the Computer Summary report, there is a column labeled, Endpoint Security Version.
For the normal cloud desktop agents, this is what is being automatically migrated from nis-20.4.0.40 to nis-21.5.0.19.
However, the on-premise managed clients are at version sep-12.1.2015.2015.
These are on servers and I am wondering if they are updated automatically or if I have to pull down a file from FileConnect to update them.
