Moving system disk between dissimilar systems

I have been tasked to "clone" a production E3500 to a development E420R.

The E3500 uses Veritas Volume management and has encapsulated / and /usr.
The E420R is not licensed for Veritas and will start out using straight
UFS.
Of course the hardware configurations are entirely different.

I tried making a ufsdump/ufsrestore of / and /usr to the C0T0D0 disk on
the E420R.
I have replaced /devices and /dev/dsk and /dev/rdsk with copies from the
CDROM boot.
I have run devfsadm (from the CDROM boot) with output to the "new" system
disk.
I "disabled" the vxvm scripts in rcS.d and rc2.d.
I have editted /etc/vfstab to remove the references to Veritas volumes and
replace them with C0T0D0 references.

My disk still won't boot.

I still get errors:

 The / file system (/dev/rdsk/c0t0d0s0) is being checked.
 Can't open /dev/rdsk/c0t0d0s0
 /dev/rdsk/c0t0d0s0: CAN'T CHECK FILE SYSTEM.
 /dev/rdsk/c0t0d0s0: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
 
 WARNING - Unable to repair the / filesystem. Run fsck
 manually (fsck -F ufs /dev/rdsk/c0t0d0s0).

... and the / filesystem is mounted readonly.

I have checked the entries in /devices and the links in /dev/{r}dsk and
everything looks correct.

What am I missing?
