We have a customer who wants to upgrade their Nagios Core checks into Nagios XI. The current Core instance is running Nagios 3.5.1 created by juju (https://jaas.ai/u/npochet/nagios-charm/0). When I attempt to import the core checks, I see that the definition doesn't seem to match the standard setup for a Nagios XI or Nagios Core 4.X instance. How would I go about changing this Core 3.5.1 service definition into something compatible with an updated Nagios instance?

Did you follow that order for all configs from the 3.5.1 system?
