Migrating from Icinga 1.x
Configuration Migration
The Icinga 2 configuration format introduces plenty of behavioral changes. In order to ease migration from Icinga 1.x, Icinga 2 ships its own config migration script.
Configuration Migration Script
Due to the complexity of the Icinga 1.x configuration format the migration script might not currently work for all use cases.
The config migration script provides support for basic Icinga 1.x configuration format migration to native Icinga 2 configuration syntax.
The migration script tries to preserve your existing template structure and adds new templates where appropriate. However, the original file structure is not preserved.
The migration script uses templates from the Icinga Template Library where possible.
Note
Please check the provided README file for additional notes and possible caveats.

Manual Config Migration
For a long-term migration of your configuration you should consider re-creating your configuration based on the Icinga 2 proposed way of doing configuration right.
