License question
 

Hi.

We currently run vB 3.8.x on our forum, and have purchased the 4.0 Upgrade. However, the site is quite customised and we can't run 4.0 and maintain our customisation. We put it to a vote, and we're staying at 3.8.x for as long as we can.

Now, we have the 4.0 license. Can I use this license on a new domain for 4.x only and leave my previous installation on 3.8.x?

If not, what can I do with the redundant 4.x license. Many thanks in advance.
