No need to shift it at all. Pick it up a couple inches above the sill height and you are good to work.

When we diy'd it we spanned several joists with a timber, just far enough back from the wall to leave room to dig the footer and lifted with lolley columns. Those need to be fixed top and bottom.

If I was DIY'ing that job I would lift one long wall, then the opposite wall, then fill the ends. That way the house doesn't shift - that's how we did it.

A pro will put two beams under near the joist ends and jack on those and the center beam - he will lift and level the whole house at once. That is easier and quicker when you have a crew and an
excavator They can excavate and pour the footer in one shot then stack or pour the foundation.

You/they will need to deal with the plumbing, but the foundation itself isn't that big a deal to do with the house on jacks.

Thousands of houses along the coast were jacked up after Sandy - like 3' - 12'.
