invalid license when installing Opmanager on a new machine

invalid license when installing Opmanager on a new machine

I m trying to migrate my Opmanager to a new machine as the old one is going to retire soon.
when I try to install version 9101, i keep getting the invalid license error message.
 
my current version on the old machine is 9101.
how do I export the license to the new machine ?
