Linux -> you use the namei fileserver (and 1.4.2 should be upgraded).

You forgot:

  0. Backup ;-)

One important thing is to preserve the permissons in the AFSIDat tree
because that contains information, too.

Only the old inode server. Linux does not use that.

That is the very safe option. 

Btw, you could use xfs instead of ext3, we have not had any trouble
with it, it's only faster.
