Acquia Dev Desktop supports Drupal multisite whereby websites share code (Drupal core, modules, and themes). Each website has its own database and doesn’t share content, configuration, settings, or displayed themes. For more information, see Multisite - Sharing the same code base on Drupal.org.
To create a new Drupal multisite, complete the following steps:
Select an existing website in the left panel.
You will use the website’s codebase to create a new Drupal multisite with a new site name, database, and files.
Click More, and then click New Drupal multisite.
In the Create new multisite dialog box, enter values for the following fields:
Click OK.
After you create a Drupal multisite, Acquia Dev Desktop will display a Multisite selector in the right panel.
Use the Multisite selector to choose which website within your Drupal multisite you want to work with. When you change websites within the Drupal multisite, the local website URL and the name of the local database change, but the local code URL doesn’t change. In a Drupal multisite, all the websites share the same codebase.
You can create a Drupal multisite locally with Acquia Dev Desktop and then host it on Acquia Cloud, like a single website installation. If you already have a multisite hosted by Acquia Cloud, you can clone it locally, creating local copy of one website’s database and files to start and then adding the others.
After you have a Drupal multisite with both local and Acquia Cloud versions, you can sync them as you would sync a single website installation.
