This standalone script allows you to migrate the basic Icinga 1.x object configuration into native Icinga 2 configuration objects.

Note

You are highly advised to read the Icinga 2 Migration documentation and understand the new dynamic configuration syntax.

Check the manual migration hints in the documentation.

This script is a bootstrapped standalone version of the Icinga Web 2 CLI module for configuration migration from Icinga 1.x to 2.x.

Note

This project will be merged into the upstream CLI once there is a stable release. Meanwhile it acts as standalone helper tool for migrating to Icinga 2.

• PHP CLI >= 5.3.x
• PHP Zend Framework

Debian requires the zendframework package installed. RHEL/CentOS requires the EPEL repository which provides the php-ZendFramework package. OpenSUSE requires the server monitoring repository which provides the php5-ZendFramework package.

Call the migrate command action pointing to your Icinga 1.x main configuration file and pipe the output to a file included in your Icinga 2 configuration:

$ bin/icinga-conftool migrate v1 /etc/icinga/icinga.cfg > /etc/icinga2/migrate.conf

Make sure that your user can access the icinga.cfg file and all included directories and files (cfg_file, cfg_dir attributes in icinga.cfg).

An example for validating the generated objects with a bootstrapped icinga2 config is located in bin/run.

These Icinga 1.x specifics are not supported:

• Regular expressions and wildcard matching
• Invalid objects ('name' instead of 'service_description' for service objects)
• Invalid templates (missing 'name' attribute)
• More unknown (not documented) object tricks
• Special macros
• Deprecated attributes and objects ({host,service}extinfo, etc)

This is by far an imcomplete list, but shows the general approach of this migration script:

• All compatible object attributes

• Keep the template tree (register 0 -> template) and import these templates (use -> import)

• Keep service relation ship to host_name and hostgroup_name

• Use the apply rules wherever possible (e.g. for service with hostgroup_name attribute, Dependencies, Escalation Notifications, etc)

• Assign group members directly

• Migrate host/service contacts for notifications into the new Notification logic

• Convert the notification options to state/type filters

• Create additional EventCommand objects for event handler migration

• Create additional NotificationCommand objects for notification migration

• Migrate the ARGn command arguments into custom attributes for commands

• Convert custom variables into custom attributes

• Replace runtime macros in command line for check, event, notification commands

• Replace runtime macros in notes, notes_url, action_url, icon_image attributes

• Migrate host parents into simple host dependencies

• Treat all intervals as minute duration literal - append m

• Exclusions in service => hostgroup mappings and group membership assignments

• Turn * (all) into a match function in expressions

• All comma separated lists are converted into arrays, if possible (except contacts for notifications)

  Icinga 1.x	Icinga 2.x	Specialities
  host	Host	.
  service	Service	object or apply rule
  . (contacts)	Notification	object or apply rule
  hostgroup	HostGroup	membership assign
  servicegroup	ServiceGroup	membership assign
  contact	User	.
  contactgroup	UserGroup	membership assign
  timeperiod	TimePeriod	only basic
  command	CheckCommand, NotificationCommand, EventCommand	cleanup required

The contact-to-notification migration generates a new notification object per unique host/service contact (also in groups) and its {host,service}_notification_command. The first_notification_delay attribute is not automatically converted.

• Better: Get an idea how the new Icinga 2 notifications work, and apply them based on your group memberships, custom attributes, or host relations!

The generic-escalation-dummy command acts as placeholder for a proper notification command. There is no way to automagically get the right notification command from the assigned contacts and contactgroups.

Event and Notification commands will be added once used. The Icinga 1.x command objects serve as Check command, and may require cleanup afterwards.

The parent hostgroup_name is not supported. Migrate this dependency manually. The host_name attribute cannot contrain multiple entries, only the first one will be processed. inherits_parent is ignored, default is enabled. By default all dependencies will disable notifications and checks. notification_failure_criteria and execution_failure_criteria are not 1:1 the same for the migration process.

Complex timeperiod strings are not processed and will result in a warning.
