Applying new license file for existing installation

Hi experts,

I have installed Sybase ASE 15.7 SP110 Developer Edition (DE) on a VM running RHEL 6.2 for x86_64. Now my company purchased a license for Enterprise Edition and my manager sent me a license file (*.lic). Now I'm wondering if I can apply this new license on my existing installation. If yes, could someone point me to the detailed steps to do that?
