Good Morning,
I'd like to thank everyone who's responded. It seems that this is
completely possible, and of course I'll make a full dump before trying
it.
Ciao,

I'd like to thank the following people:
rmo@teltechlabs.com (Robert Ogren)
casper@fwi.uva.nl (Casper H.S. Dik)
kwthomas@nsslsun.nssl.uoknor.edu (Kevi...)
David.Niemi@oasis.gtegsc.com (David C. Niemi)
Ole.H.Nielsen@uni-c.dk
and anyone elses that I haven't gotten yet.
What I feel was the most useful piece of information was the following
from Casper Dik:
SunOS 4.1.x disks (That is 4.1.x, not 4.0.x or earlier) can be attached
to Solaris 2.x machines without problem, as long as the disks interoperate
with Solaris. (SCSI is some kind of black magic, there's no predicting
which disk will work with which computer until you try it)
SunOS 4.0.x filesystems can be used on SunOS 5.x, provided they have
been converted to 4.1.x filesystems on 4.1.x hosts.
If you're not sure whether the disk was newfsed under 4.1.x or earlier,
you can try the following commands on a 4.1.x host:
# dumpfs /dev/<disk> |head -1
magic 11954 format dynamic ...
If the format is dynamic, the disk can be used on SunOS 5.x.
If the disk format is static, it needs to be converted with fsck -c.
(This should only be done on unmounted filesystems). fsck -c is
only in SunOS 4.1.x, so this should be done on the SunOS 4.1.x host.
See fsck(8) for details.
Ciao,
