Sorry, my misunderstanding. I thought it was the same hardware, but a 
duplicate drive for dual booting.

Right, you could clone the disk, but then you would need to adjust your kernel 
for the hardware it will be running on.  If you have missing drivers it won't 
work.

I expect quickpkg will work, but it depends on the application's runtime 
dependencies.  Use quickpkg for those too if the package asks for any and see 
what you get.

Ideally you should be looking at updating the application, or finding an 
alternative which is still being maintained.
