Typically you will not need a new license key to upgrade to Blueprint 4.2. However, a new license key may be required for licensed features that did not exist when your current license key was issued. If you think this might be the case, and you are a direct customer of Pharos, please contact Pharos Sales for more information by calling 888-864-7768 ext. 2 (toll free US and Canada) or 585-360-1010 ext. 2. Otherwise, please contact your Pharos reseller.
