jetted tub must be moved, 5x5 corner unit--help--what difficulty will I (or a plumber) have lifting off cement pad & base without damage, to new bath for disabled son?

The tub was positioned into a blob of wet concrete when originally installed. Drying concrete sucks tub to its surface creating positive grip. I assume it is self-rimming tub ( aka "drop in") with edges sitting on top of the pedestal.

First, cut and remove any caulking around the edge of the tub. Then, cut about 3" above and around the but to expose the lip. The lip should have screws in it. Remove the screws all the way around on vertical and horizontal lip. Open service door, disconnect h/c water and overflow. Take 8' long piece of 2"x 4", insert it bellow the tub, lay short piece of lumber under 2x4 - and slowly apply pressure to the but. With neo-angle tubs you should have 2 access doors. Have other person do the same through the other door. Once you break the grip tub will lift easy.
