You can enter the same product key on all your Drupal sites, so they share the user licences of one subscription. A person who edits on three sites uses one licence. Use this page when you add a site, or move your editors from an old site to a new one.

## How sites share licences

- Each site reports its editors to dxpr.com, together with its domain name.
- An editor counts once per email address, however many sites they edit on. Two accounts with different addresses count as two licences, even for the same person.
- Excluding a user on one site only stops editing on that site. They keep their licence while they can edit on another site.
- The **Content Items** tab of each site shows the content items of that site.

## Set up

1. Copy your product key from [dxpr.com/getting-started](/getting-started)or from the first site.
2. On the next site, go to **DXPR Studio** > **DXPR Builder** > **General Settings**(`/admin/dxpr_studio/dxpr_builder/settings`).
3. Paste the key in **Product key** in the **License** section and click **Save settings**. [General settings](/hc/documentation/learn-dxpr-builder/admin/general-settings)explains the storage options.

## What you see

The **User Licenses** tab (`/admin/dxpr_studio/dxpr_builder/user_licenses`) is the same on every site: it lists the editors of all sites that use the key. The **Sites** column shows on how many sites each person edits. Click it to see the domain names.

## Move editors to a new site

1. Save the same product key on the new site, as above.
2. Before the old site goes offline, exclude the people who will not edit on the new site, as described in [User licences](/hc/documentation/learn-dxpr-builder/admin/user-licences).
3. After the old site is gone, open **User Licenses**on the new site. Click **Delete license data** for each address that has no account there. This removes the address from all sites.

## If you don't see your editors

- **A person counts twice.** Their accounts use different email addresses on different sites. Use one address for the person on every site.
- **A person still counts after you excluded them.** They can still edit on another site. Open their **Sites** link and exclude them there too.
- **Delete license data is missing for a person.** The link only shows for addresses without an account on the site you are on. Exclude the account instead.
- **The table is empty.** The tab needs a connection to dxpr.com. See [Licence and product key errors](/hc/documentation/learn-dxpr-builder/troubleshooting/licence-and-product-key).
