You will need to activate your license of MAX 2010 separately on the new system. You cannot transfer any 2009 licenses to 2010. They are different license types. Keep in mind that if you have problems, that the software is not supported on Windows 7 64-bit yet and you will be hard-pressed to get technical support. Under Subscription you are allowed to continue to run your 2009 product, so long as you do not use both at the same time.
