I appropriated a spare desktop PC and practiced the upgrade there first.
There were a few changes in the nagios.cfg file that I needed to make,

I don't think so, but that's how I do things with host groups and
service groups. I have the dependencies and escalations defined in
separate config files, but wildcards let me have one service escalation
definition, one host escalation definition, and one service dependency
definition.

I'm running 3.10 right now, and you can put a hostgroup in the
dependency definition.
I have hundreds of Windows servers monitored. Occasionally, the agent
gets starved for resources during backups or otherwise clobbered. That
used to cause a slew of notifications, since none of the checks worked,
but the host could still be pinged.
I set up a service dependency so all the services defined for the
Windows hosts are dependent on a check of the client's version number.
The client version is checked more often than the rest of the services.
There isn't a threshold: if it's not OK, the client needs to be fixed:
define servicedependency {
hostgroup_name dev_windows_servers,windows_servers
service_description Client Version
dependent_service_description *,!Client Version
execution_failure_criteria w,c
notification_failure_criteria w,c
}
I use a wildcard to get all the services on the host, but since "Client
Version" is also one of the services assigned to the
(dev_)windows_servers hostgroup, I had to add the !Client Version
exception. That's the entire contents of my servicedependencies.cfg
file, though.
For the sake of completeness, here is how I defined the escalations I
needed:
define serviceescalation {
hostgroup_name windows_servers,Agentless_Checks
service_description *
contact_groups +nogmgr
first_notification 3
last_notification 0
}
define hostescalation {
host_name *
contact_groups +nogmgr
first_notification 3
last_notification 0
}
