I have a few "big old upright" piano moving tips that might be of help
to some of the readers.

- Lift from the treble end of a big old upright, because the cast iron
frame weighs less in the treble.  Bend your knees and use the legs.

- Put one hand under the keybed all times while piano is on dolly,
in case it wants to fall over.

- Push from low when there is difficulty moving the piano forward.
The dolly will magically pop up when the person in front lifts to go
over and up steps.  Pushing from high forces the front into the ground
working against the other person who is trying to lift or take weight
off.  The dolly will not pop up and hits against the first step when
the piano is pushed from too high.  Pushing from low minimizes
friction.

- Use a ramp, lift, pipes, rollers and anything else that takes stress
off the body.

- Is using a ramp not possible going up stairs?  Then flip piano on its
side on top of the dolly, roll it up to the stair case bottom of piano
facing staircase.  Hop one or two stairs than bring piano from 90 to 45
degrees bottom now rests on blanketed stairs.  Person on bottom pushes
from low.  The person on top pulls from low.

 - Person on top going up stairs.  Removal of "bottom panel" provides
a great place to pull from and/or use a rope or strap.

- Remove the casters when going up or down several stairs.  Check for
protruding screws from bottom.

- Moving big old upright away from wall.  Use mostly the thigh because
you can push from low and the legs are stronger and more durable than
the back.  Pushing from low means not fighting the hand under the
keybed that is trying to lift taking weight off the front wheel.

- Protect the home and the piano.  Use blanketed plywood on tile floors
and against the walls the piano will in all likelihood come in contact
with.
