Xray licence on Jira Dev Server

[NA]

Hello,

Our enterprise has a production Jira server and a development (test) server.

Could we use the same license key on the both servers? Could we have a developer license for Xray (like developer license of Jira) ?

Regards,

I've found the solution. 
I copy here for anyone needs it:

The technical contact for the license can generate a developer key by following these steps:

1. Log in to My Atlassian.

2. Click the Atlassian product in question - your account management screen will display.

3. In the Actions section click "View Developer License."

4. Review the Developer License agreement.

5. Finally, click "View" to agree. A license key will be presented. Copy and paste this key into your development server.
