Une semaine de travail et de comparatifs...
Les procédures ont évolué depuis 2007

Mais certains éléments peuvent t'aider à bricoler si tu pars pas d'une installation saine.

En ce moment j'en suis à chercher un outil de copie des fichiers en lignes sur le site vers mon installation locale. Les logiciels proposés par Drupal font surtout du versionning obligatoire même si on ne gère qu'un seul projet.

C'est en anglais mais ça répond à ton cas précis et ça a été mis à jour en Mars 2012:

(Optional) Adding a new site to an existing Drupal WAMPServer instance
You may use these instructions to add an additional site to an existing single site WAMPServer Drupal install. In that case, follow along but skip any steps you've already done for your existing installation, like installing WAMPServer and configuring your first site. You do still have to add a new database and database user, DNS/hosts entries, extra site directories and the Drupal install steps. Depending on your Apache configuration, you may also have to turn on Virtual Hosting if you were not using it before, and configure the virtual hosts for localhost and your existing sites in the virtual host steps.

Optional) Migrating or copying existing sites instead of installing new ones
These instructions will also help you migrate an existing site to a multi-site WAMPServer install. A common use-case for this is making a local development server on your Windows machine, where you can test changes to a copy of your production site hosted on a server somewhere. In that case, follow the instructions here but instead of creating empty databases in PHPMyAdmin, you will be creating an empty database then loading in a SQL backup taken from your production server. Instead of downloading a stock Drupal version from drupal.lorg and unpacking it, you will most likely use an existing copy of your Drupal files, copied from your existing server. Or you might use source control software such as git or svn to get a copy of the files on your local machine. In that case the location of the files should be substituted forc:\wamp\www\drupal-7.0 in the examples here.

A bientôt.
