Designating a laptop for Whonix (Qubes-Whonix) use is recommended. Would there be any benefit to building all new templates for new Whonix hardware https://www.qubes-os.org/doc/building-whonix-template/? Meaning migrating from a combined clearnet + Whonix hardware.
Apart from learning experience not much. Qubes-Whonix templates are build by installing from official, remote Whonix binary repository deb.whonix.org…
…unless creating your own Whonix binary repository by configuring variables
And then also upgrading Whonix from source code rather than Whonix binary repository.
