Look into free virtualization solutions (libvirt or something similar), 
and run DCs (or, if possible, everything) as VMs so you can just copy VM 
images around. Having to recreate just the VM host when hardware needs 
replacement reduces headaches and time needed. Plus, you need less 
hardware.

That should work, assuming the old Debian's kernel can deal with the new 
hardware.

(Which is another advantage of virtualization, that's all hidden from 
the VMs and can't cause problems.)
