# How to change configuration backend

LemonLDAP::NG provides a script to change configuration backend easily keeping history. It is set in LemonLDAP::NG utilities directory (`convertConfig`).

## How it works

The `convertConfig` utility reads 2 LL::NG configuration files (`lemonldap-ng.ini`):

- Current: to extract all configuration history
- New: to write all configuration history

## Let's go

- Prepare your new lemonldap-ng.ini file
- Configure your new backend (create SQL database,...)
- Launch that:

    convertConfig --current=/etc/lemonldap-ng/lemonldap-ng.ini --new=/new/lemonldap-ng.ini

- Install the new lemonldap-ng.ini file at the place of the old file in all LL::NG servers
- Restart all your Apache servers
