The are lots of easy methods, depending on your exact situation:
When you have only one disk, just add the second one, make a
filsesystem on it (man newfs) and copy:
cd <old> ; tar -cf - . | cd <new> ; tar -xf -
When a fast network is availble, copy your 850Mb to another system
(see above), remove the old disk with the new one and copy back.
When a tape is availbe: tar it to tape, replace, "untar"
Same with floppies, but you need 400 floppies and a lot of time ..
(Use tar to write upto 2Mb to a normal 1.44 flop)
Good luck.
P.S. In all cases, you should first stop your news serverses, the
system should be "frozen" when doing such a copy, or you will loss
