i haven't done it myself, but i would have thought "yes" since sun made a big
point of the cpus all being modular and upgradeable.  however, you might have
to swap all the ram - i believe they use 60ns (or better) ram for the 300Mhz
or less CPUs and 50ns (or better) ram for 360Mhz and up.

someone was also pointing out you can use the new modules even in the lowly
Ultra5/270 to upgrade them..
