What happened to my configuration files?
========================================

Your host and service configuration files were moved to the $sysconfdir/icinga2/repository.d directory.

This allows you to manipulate those files using the "icinga2 repository" CLI commands.

Here are a few commands you might want to try:

# icinga2 repository host list

# icinga2 repository service list

# icinga2 repository --help
TEXT

echo "Migrated $host_count host(s) and $service_count service(s)."
