We are preparing our older ZCM 11.3.2 server for ZCM 2017. But we must first upgrade to 11SP4.
The Upgrade was run without any error messages in the system update logfile.
The server has the new agent 11.4 installed and also the version of the database is 11.4.0.
But the status in ZCC is still Pending with stat "Awaiting Reboot"

I booted the server several times and give him time, but it suck.

I see also that the agents are not updated on the /zenworks-setup page.

What is wrong here?
