How to convert trial code to product code

Converting trial code to product code is a simple process of installing a license activation kit that you download from IBM after you purchase the product. You will not have to uninstall or reinstall the product.

If you purchase floating licenses, and you want to use license keys to control usage within your organization, you will instead log into the Rational License Key Center to download the Rational License Manager and generate the appropriate license keys.
