I have 21 endpoint right now that are "down".

These endpoints was installed with the previous version Agent, following an recent upgrade of the central server (before i was able to update the installation media for new servers.)

I assumed that when agents were installed with an older version, they would just upgrade. instead they are broken and does nothing.

I come with a background from SCCM, where tools exists that can detect and fix certain issues regarding the SCCM client Health.

Does any tool like this exists for Endpoint Central?

Currently the only solution to fix these agents, is to uninstall them and reboot. manually, which is a pain
