Change host id in license file for cadence 16.5

 Hello! I want to install cadence 16.5 software to a different pc and since i have purchased only one license, i have to transfer the license server to the new machine.How can i do it?
From what i understand, each license server has its own license file based on the host id, can i change something in the license file manually or should i contact cadence to request the change?
Thank you in advance.
