Hello Mike,

You'll need to contact the ANSYS account manager or ANSYS Channel Partner or the Sales person who supplied the license. If you're using LSTC license, you will need to generate the LSTC_SERVER_INFO file from the new machine and send it to the above representative. They will use the information in the LSTC_SERVER_INFO file to send you a new license file for the new machine.

For Linux instructions, search online for "LSTC License Manager Installation Guide".
