How do you remove home firewall and its license from a computer so the license can be used on a different computer.

Hello there,

Thank you for contacting the Sophos Community.

You should request a new Sophos Firewall Home license.

Regards,

normally easy: delete the vm and use the licence on the new machine.

I often changed hardware and re-used the lic in the past. never had any problem.

I tried that but it did not accept the license during the install on the physical computer. I pasted the license from the email, just as I had done on the VM, but when I entered the license, the "Next" button stayed greyed out, so I could not proceed with the installation. I received a second license in another email, and I was able to install the OS on a physical device. 

My curent test machine has been on a number of different hardware devices, currently on a VM without any licence issues.
