I suspect this is too late, but:

1. Boot the upgrade tape

2. Select "Restore individual partitions"

3. Restore / and /usr; Don't restore /files.

4. exit to single user shell

5. mount your old /files somehere.
	* go look at it
	* several places ( cluster, spool, var?) will be directories
	named sun386.sunos4.0.0 (approx., obvious)
	* delete them ( rm -rf ...)
	* umount the disk

6. Somewhere on the ramdisk you are working from is the script that does
the work. Maybe /usr/etc. The script is in all uppercase, some name like
UPGRADE, or INSTALL.

[ I'm sorry, I've DONE this, it works, but to find the actual name I'd
have to shut down my node, boot the installation tape, and check.  I can't
do that.]

7. edit the script. Look for the case where it does the /files system.
Delete the line where it does a 'newfs' on the /file disk.

8. Make sure the application tape is in the tape drive. Execute the script
you modified in (7). Say n to / and /usr, Say y to the /files prompt.

Variations on this are possible, but I haven't tried them.
	1. Unloadc all 'clusters' before starting the procedure. They
	are deleted in step 5, above. If you 'unloadc' them first you
	can probably skip step 5, a small tree of links will be left
	behind. [ I did it the way I described, I'm sure this
	variation would work, but I haven't done it]

Hope this helps.
