Glad to hear that 25 hosts are allowed with the free version now !
The download page was updated, but looks like the packet itself wasn’t? I updated my RAW 1.6.0p22 to the free version 2.0.0.
After updating my instance fails to start:
Error: Sorry, in this demo version at most 10 hosts are allowed. Checked 21 hosts.
EDIT: Nevermind, found the answer on Migration to the CMC - Switching from Nagios to the Checkmk Micro Core
Cheers
