  I have successfully installed VMS 4.6 over MicroVMS 4.7 on an RD53 with
two satellite nodes.  Performance is not an issue; disk space is.  You will
need to either put the paging/swapping files for the satellites on their
own disks (if they have them) or on a second disk on the boot node.

  My procedure was the following:
	1) Break down the installation tape by $ COPYing the save_sets
to a disk, then restore the first save_set to a disk directory.  You will
find the file KITINSTAL.COM, which you will need to edit.

	2) Search for the section containing a reference to "RD54", and comment
out the lines which test for it.

	3) Search for the section referring to VMS4.6, and if you are running
4.7, add that to the logical statement (or comment the whole thing out)

	4)  There was one more thing involving a file which it wanted which 
would only have been there if you had already installed clusters.  I will
try to find a DIFFERENCES file on KITINSTAL.COM; I know I made one...and
will post it to the net.  Anyway, you comment that check out also.

	5) Reassemble the first saveset by backing it up to a disk file.

	6) Recopy the bunch of modified savesets to a new TK50, or if there
is room, you can copy they to DUA0:[0,0] and run VMSINSTAL on them from there
(much, much faster than a TK50).

	Voila'

(MUCHO faster).
