That doesn't always work if the two machines have different enough
hardware that the install creates a different initrd file. Of course
you can make a new initrd file.
Whichever method you take depends on your skillset and patience.
If you swap whole machines you don't have this issue. If you swap disks
from different hardware, the brute-force approach is to do an install on
the destination box or identical hardware and use the /boot and
/etc/modprobe.conf generated there with the rest of the system from your
configured setup (making sure both are updated to the same kernel
version). If you go this route, the new setup can even be built under
vmware. There are less drastic ways to get a working initrd, but you
have to know as much as anaconda does about hardware and I don't think
much of that is well documented.
Is there an automated way to build a working initrd when running from a
live CD that has detected the runtime hardware?
