This would require a modification of /etc/vfstab after it was copied to
the new partition.

Sun's versions of dump and restore (ufsdump/ufsrestore) is what I
recommend.  Here's a rough procedure to follow (from my failing memory).
If this is wrong, we'll still be OK since the original OS is not going
to be corrupted or removed;

- cd /
- umount /space
- newfs -i 8192 /dev/dsk/c0t0d0s0
- fsck /dev/rdsk/c0t0d0s0
- mount /dev/dsk/c0t0d0s0 /mnt
- cd /mnt
- ufsdump 0f - /dev/dsk/c0t0d0s7 | ufsrestore rf -   (will take 1-2 hours)
- rm restoresymtable
- edit /mnt/etc/vfstab (change c0t0d0s7 to c0t0d0s0 and vise-versa throughout)
   note each occurs twice per line
- cd /
- umount /mnt
- fsck /dev/rdsk/c0t0d0s0
- installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c0t0d0s0
- sync
- halt

at the eeprom prompt type

- setenv boot-device disk:a
- setenv diag-device disk:a
- reset

at which time the machine should reset and boot on the newly copied
verison of the OS.  Type "df -kl" to verify the partition sizes.
