I have a neoload license for a machine, but I want to make it floating so I can use it intermittently on other machines as well when I'm not using it on the one it is installed right now.
The editions "Standard" and "Professional" are node-locked. This means that you can design on any machine with the 'No License Key" mode, but you can run the Load Test from a single controller only.
The Enterprise edition license allows you to run different tests from different controllers at the same time to do concurrent testing (the VUs are split between the controller).
Feel free to contact your sales contact to get more information.
