welcome to the forum.
what licenses do you have, what software and version, perpetual license or subscription?
in order to transfer the license, Rockwell will have to know the software type, license number, who bought the software.
you will also have to fill out a form stating that you own the software and are transferring the license to someone.
i had to have this done when we bought a machine from an oem ad they were required to buy the software.
regards,
james
