will upgrading my machine affect the vray license?

[chocky]

Basic question from someone who isn't very techie minded: I'm planning to put a faster CPU in my computer. When authorizing vray does the machine ID relate to the hard drive or to the CPU? (ie. would the upgrade affect on the Vray license on the machine?) I can't afford any downtime at the moment so I need a smooth changeover

thanks in advance
