Well... actually, ext2 is readable by Solaris... there's a read-only
ext2fs driver for Solaris at www.sunfreeware.com... but not SunOS4.
There should be no issue transferring the data in over NFS, or using
Linux to read the UFS partitions.  UFS read support is pretty decent,
but the read/write support is iffy at best.

Yeah, I don't think that will be an issue.  The issues I see are:
* Transferring of the data... shouldn't be *that* bad... just be
  careful...
* User shell configuraations (.cshrc, .profile, etc.) will be off
  from what they were in SunOS4... your users should expect to have
  to fix this.

I think it should be fairly straightforward otherwise... good luck. :)
