Import from core to XI

[kbauma01]

I'm new to NagiosXI. I've imported my config files (Commands-->Time Periods-->Contact Templates-->Contacts-->Contact Groups-->Host Templates-->Hosts).

I brought in 2 servers to start with and when I try to delete them via the XI GUI I get this:
Host Deletion Error
Host cannot be deleted using this method

So went to CCM and deleted them from there but when I do that I see

An error occurred while attempting to apply your configuration to Nagios Core. Monitoring engine configuration files have been rolled back to their last known good checkpoint.

<div>Error: There are no services defined!</div><div>Error: There are no hosts defined!</div>

Did you import services?

My notes (which shouldn't be trusted) say to import in the following order.
commands.cfg
timeperiods.cfg
contacttemplates.cfg
contacts.cfg
contactgroups.cfg
hosttemplates.cfg
hosts.cfg
hostgroups.cfg
servicetemplates.cfg
services.cfg
servicegroups.cfg

copy commands.cfg to /usr/local/nagios/etc/import/
cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh
Continue with timeperiods.cfg, and run the reconfigure script. Repeat until all files are imported.
