I gave the component swapping some thought, but I don't do so hot with
swapping cpu's and have a number of 'spare' cpu's to back up my claim.
Who'da thunk that a shirt pocket wasn't safe for cpu pins? swapping
drives is way easier :).<br>
<br>
I'm kinda assuming this should work - this is why I keep a spare cold
server. if something blows up in the middle of the night I figured I'd
just drag hard drives across and be happy again in 3 minutes.<br>

boring will my day be if I pull the three drives from server 1 and
insert them into server B (I don't mind a few minutes of downtime to
make the switch and reboot)? Did I just upgrade my server? Or is
linux likely to insert some excitement into my life?<br>

This depends on a variety of issues. We do a system cloning at work for
our new systems and find that things go funny sometimes, in particular
with things like interface name persistence. When cloning RHEL between
hosts, it notices the MAC addresses are different and blows away our
bond configuration, for example. Ubuntu (Debian?) remembers old
interface names via either hal or udev, so while your old configuration
for eth0 stays safe, your NIC in the new hardware would be eth1 and
ignore it.<br>
<br>
I'm assuming you are not using any sort of system-configured hardware
raid and the hardware is identical other than the CPU and RAM. And if
it is identical, have you simply considered swapping those two
components?<br>
