At City university when the Gould PowerNode UTX-32 systems were
retired, the Fujitsu SuperEagles running on the 6040 NFS server were
moved to a Sun4/370.

Unfortunately I wasn't directly involved (it was *just* before my
time), so I have no useful notes, though they were reformatted to UFS
and I would have expected "just" low level formatted at the same time.

I can say we were glad to have them, as the garbage drives Sun shipped
in the '370 sized deskside units repeatedly vibrated themselves into
non-function as the "ancient" SuperEagles Just Kept Running...
