Upgrading from 9 to 10 without internet access

Hi, 

we're upgrading an onsite customer from 9 to 10, but the server doesn't have internet-access, so it fails with an error saying "There was no endpoint listening at https://license.superoffice.com/LicenseSvc/LicenseService.svc".

We used the "Test upgrade" checkbox in DBSetup since this is their test-environment, and had hoped that would cause it to not try to contact the license server, but it did anyway.

We have a license file from SuperOffice for v10, but probably need to get the version upgraded before we can give it the license file manually in CRM Admin.

Does anyone have any tricks here? How to upgrade without having internet access?
