The configuration is entirely in /etc/ccd.conf. That's all the

You'd have to ensure that you have the disks on the new machine in
the ccd.conf in the same order with the same interleave and then
it should work. I used a random i386 box to recover my data when
my AS 200 4/233 w/ ccd stipe lost its power supply. The only
problem that I had was the fact that i386 and alpha look for their
disklabels at different offsets, but that's a different issue.
