The big issues are breaking the floor, digging down to the
existing pipe, and cutting the existing pipe.
If you have a clean cut/break on the existing cast iron going to
PVC use no hub clamps. These are thin rubber connectors with a
full stainless shell and band clamps like these:

You can also use the Fernco type connectors, but the no hub style
keeps the pipe in line better. They can be cantankerous to
install. Slide the stainless portion up the pipe. Install the
rubber part to the stop and then fold the other half back on
itself like rolling up a pants cuff. After getting the pipe
installed, roll the cuff onto the other pipe and slide and tighten
the stainless clamp.
