The title pretty much says it all.

Thanks!

I've never done it, but I can't see why any alterations would be needed.

Depending on what kind of flooring you have in your bathroom, the old two piece toilet may leave a "foot print" on the flooring. The new one piece toilet might not cover that old foot print entirely. About the only fix for that is to replace the flooring in the bathroom, but that's not always in the budget.

Those pictures give you the standard rough in measurements for toilets. As
long as the old one was a fairly recent standard installation, anything
bought new today should fit.

Of course, we don't know what type of 2 piece toilet you had. I had a 2
piece like this in a basement bathroom many years ago:

The tank was bolted to the block wall. The toilet was roughed in when there
was no finish wall so when I redid the bathroom I had to use furring strips
instead of a stud wall to leave myself enough room for the toilet. I ended
up with less than 1" between the back of the toilet and the baseboard.

I only point this out so you'll be aware that anything non-standard with
your current install could make it a little harder to swap the toilets.

Another thing to consider is the shape of the base. In that same basement
bathroom I replaced the "new" toilet with an even newer one several years
later. The bases were different shapes/sizes and you can see the outline of
the old toilet in the linoleum flooring if you look carefully enough. Due
to fading and cleaning over the years, the newly exposed area is slightly
darker than the rest of the floor. Even a tiled floor might show some
discoloration or there might be something that is now covered that will be
exposed when the toilet is replaced. The only way to find out is to pull
the old toilet and see what it looks like underneath.

One last item... it's not an "alteration" but you should do a careful
inspection of the area under the existing toilet before installing the new
one. Check the subfloor for rot, check the closet flange for cracks, check
for loose tiles, etc. As long as the toilet is off, you should make sure
the area below is it as close to perfect as possible to ensure years of
trouble-free enjoyment of your new toilet.

Also, while you have the old toilet off, clean off any wax around the floor flange and caulk between the floor flange and the flooring. Also fill any holes in the floor flange itself (except the big one) with caulking after removing any wax that would prevent the caulk from sticking. That way, if you ever develop a leak at the base of the toilet, the water will leak out from under the toilet onto the floor rather than into the floor below. That way, you're alerted to the leak before it has time to do any harm and cause any wood rot or serious water damage to any ceiling below.

However, this same advice would apply in every instance where a toilet has been removed, not just when you're replacing a two piece toilet with a one piece toilet.
