Updating the plugin

The plugin usually enforces compatibility with any previous version. Changes are automatically performed on the database and new sections are added to your config.yml and lang.yml files. Just replace your old version of the plugin by the latest one, and let the server restart (reloads are not recommended for upgrades). There are nevertheless a few point to bear in mind while upgrading:

Upgrading from a 2.x version

Do a backup of you database before upgrading. Although there is a new separation between Name and DisplayName, you should not change any of your achievement Name parameters, as these are the ones currently used in your database. You can use more database-friendly Name parameters for new achievements you create.

If you want to use PostgreSQL, you will have to add the new config parameters in you config manually (simply copy-paste from default config).

Upgrading from a version prior to 2.0

You will have to generate a whole new config.yml and lang.yml, or do at least one restart with a plugin version between 2.0 and 2.4.4.
