Upgrading Icinga 2

Upgrading Icinga 2 is usually quite straightforward. Ordinarily the only manual steps involved are scheme updates for the IDO database.

Upgrading the MySQL database

If you're upgrading an existing Icinga 2 instance, you should check the /usr/share/icinga2-ido-mysql/schema/upgrade directory for an incremental schema upgrade file.

Note

If there isn't an upgrade file for your current version available, there's nothing to do.

Apply all database schema upgrade files incrementally.

# mysql -u root -p icinga < /usr/share/icinga2-ido-mysql/schema/upgrade/<version>.sql

The Icinga 2 DB IDO module will check for the required database schema version on startup and generate an error message if not satisfied.

Example: You are upgrading Icinga 2 from version 2.0.2 to 2.3.0. Look into the upgrade directory:

$ ls /usr/share/icinga2-ido-mysql/schema/upgrade/
2.0.2.sql  2.1.0.sql 2.2.0.sql 2.3.0.sql

There are two new upgrade files called 2.1.0.sql, 2.2.0.sql and 2.3.0.sql which must be applied incrementally to your IDO database.

Upgrading the PostgreSQL database

If you're updating an existing Icinga 2 instance, you should check the /usr/share/icinga2-ido-pgsql/schema/upgrade directory for an incremental schema upgrade file.
