If you are moving your application from one hardware platform to another ie, legitimately, then the ISV should be willing to issue you with the necessary files to port it.
We know how to change the hostid and most license managers use that and not the MAC address. The hostid is computed from the MAC address but we can change the hostid but changing the MAC address could prove difficult.

sethostid
GETHOSTID(2) Linux Programmer's Manual GETHOSTID(2)
NAME
gethostid, sethostid - get or set the unique identifier of the current host
SYNOPSIS
#include <unistd.h>
long gethostid(void);
int sethostid(long hostid);
DESCRIPTION
Get or set a unique 32-bit identifier for the current machine. The 32-bit identifier is intended to be unique among all UNIX systems in
existence. This normally resembles the Internet address for the local machine, as returned by gethostbyname(3), and thus usually never
needs to be set.
The sethostid call is restricted to the superuser.
The hostid argument is stored in the file /etc/hostid.
RETURN VALUE
gethostid returns the 32-bit identifier for the current host as set by sethostid(2).
CONFORMING TO
4.2BSD. These functions were dropped in 4.4BSD. POSIX.1 does not define these functions, but ISO/IEC 9945-1:1990 mentions them in
B.4.4.1. SVr4 includes gethostid but not sethostid.
