Covers the license the separation of test and productive web site

Dear Sirs,

Nearly a year ago we bought the bridge theme. The theme is used in a test scenario on the productive server on a test web site without public access. Now we have planned to move the test web site to a dedicated server. The productive web site is still running without the bridge theme.
If development is finished the test web site will be switched to productive web site. When it runs fine, a copy of the new productive site shall replace the former productive one and become the new test web site for further development. From this moment, there would be two running instances of bridge theme:
https://productive_server/web-site.tld and
In my understanding is it only one application in two stages.
The question is: does the current license fit the test/productive scenario?

Thank you very much in advance
Best Regards
