[Pkg-nagios-devel] Bug#849915: provide hints for migrating from nagios3 packages

[Daniel Pocock]

Package: icinga2
Version: 2.6.0-2
Severity: wishlist

Now that nagios3 is being removed[1] from the next stable Debian
release, more people will potentially try to migrate to icinga2 or other
solutions.

Could you provide any tips in the README.Debian file specifically for
people in that situation, e.g. a nagios3 user on Debian wheezy or jessie
who is migrating to icinga2 (either from backports or after upgrade to
stretch)?

I notice this file in the package already:

/usr/share/doc/icinga2/markdown/22-migrating-from-icinga-1x.md.gz

and as Icinga1 was a Nagios fork, it appears most of it is also useful
to a Nagios user.

To make the experience for package users easier, it might be useful to
provide some or all of the following:

- comments about the way the nagios3 and icinga2 packages exist on a
Debian system, for example, the config file locations, related packages
like nagios-nrpe-server and their equivalents in the icinga2 world

- a list of the pages/sections of documentation that are essential
reading for somebody who already has basic Nagios knowledge

- if possible, a quickstart procedure for running the migration, with
command line examples specific to a Debian system and file locations.
Even if there is not really a "quick" way to upgrade, a step by step
procedure that would help users who used the original Debian nagios
package files without too many changes.

- should people migrate their config directly from nagios3 to icinga2,
or should they migrate their config to a database and then use some tool
to automatically generate icinga2 config files from the database?  Are
such tools already in Debian or are there RFP/ITP bugs for them?
