Hi Folks,  Not a problem!  You could tip the piano up-side-down
and that would be fine too.   Just be sure there is a rug or soft
'bumper' between the floor and the bottom-side-edge, to prevent
damage to that edge when the piano is tipped onto the dolly.

What's also important is not letting the piano travel on its own
wheels.  When the piano is moved -- whether from the house to the
truck or from state to state -- it should be elevated off the ground.
(Do not roll it down the sidewalk on its own wheels.)

In the moving van, place 2x4 boards under the bottom of the piano
like this: :|    |: (the 4" side down; the dots indicate the wheels).

This distributes the weight of the instrument over a large square area
(approximately 90 square inches) as opposed to the wheels, which focus
all of the weight of the piano onto a four square inch area where the
wheels make contact with the floor.

Musically,
