The first critical question - do these 2 machines have the same binary 
architecture.  SUNs and Mac PPCs have one byte order while Intel 
machines (Linux or Mac) have the opposite.  If they have the same byte 
order, simply copy oldmachine_1 to newmachine_1 etc.  Note that disk 1 
has special files on it, whilst disks 2 to n are indistinguishable.  But 
note that you cannot copy 2 data areas from old to one data are on new - 
the file names will conflict.

If the 2 machines are of opposite byte order, then things are trickier. 
  I wrote a stand-alone program call REBYTE which will read one file 
area in one byte order and write another file area with the correctly 
swapped files of the same name.  Run this on newmachine cross-mounting 
if possible oldmachine's disks.  If that does not fly, then binary copy 
oldmachine_n to a scratch area on new machine and then translate that to 
newmachine_n.
