Usually most vendors - like PTC and such - have an automated generation 
system in place that can send you a new license file.  In the case of 
PTC you click on a web shrinkwrap-EULA that says that under penalty of 
law you will remove the software from the old machine before installing 
it on the new machine.

However flexlm in a lot of cases is tied to the MAC address and you can 
either move the ethernet with that machine if possible or re-write the 
MAC on the new machine in a pinch.  Same with re-writing the hostid on 
'nix machines.

However these should be used as a last resort for "OMG! The server just 
died!" problems.  And even then the vendor will likely generate you a 
license faster than you can re-write your MAC.
