No. All legacy customers can enter their original Request Code at http://pathfinderpc.com/license to obtain a free upgrade to a PathfinderPRO license. You will only receive Pro functionality for as many original server licenses as you currently own. The new PathfinderPRO ships with 2 server licenses. If you only own one legacy license, that license will be upgraded to all of the capabilities of PathfinderPRO, but you will not obtain a free second server license for clustering. To obtain a second server license, you will need to purchase the upgrade product. Legacy customers who have already purchased two licenses in order to run a cluster can upgrade both licenses through the licensing web page to obtain full dual-server PathfinderPRO functionality. To obtain your free upgrade, go to the PathfinderPC licensing web page and create an account using the original legacy request code. Upon successful account creation, upgrade licenses will be generated and displayed. Starting with PathfinderPC Server 4.20 and later, you can access, enter, and upgrade the licensing information through the File menu of PathfinderPC Server.
