Hi,

This might be somewhat stupid question. But I need to confirm.

I bought a perpetual Wowza media server license and would like to install it on a customer site server sooner or later.

Before I install that license on a customer server I would like to test it in my office first as the developer license only

allows few connections which is not sufficient for actual load/performance testing.

Is it possible to use the perpetual license on a test server for a limited time and re-install it on an actual server?

Of course I will not use that test server after installing it on a customer server.

Thanks

Yes, you can install Wowza on multiple servers and use the same license. You will only be charged for the instances of Wowza that are running.
