Lowering a ceiling

I have a 3 season room with a ceiling fan securely mounted to the roof joists. The room currently has a plywood ceiling. I am adding a 2 inch layer of rigid foam, 3/4 strapping, and 1/2 inch sheetrock --- lowering the existing ceiling by 3.25". My question is whether I have to lower the fan or can I just leave the original mounting hardware in place and install a new canopy to the new sheetrock ceiling. I have plenty of clearance for the blades --- it's a 10 foot ceiling and the fan hangs 20 inches down.

Remove the existing electrical box and build it down the thickness of the new ceiling with solid blocking behind it.

Is the existing box fan rated?

The box needs to be recessed no more than 1/4" from the face of the drywall. You need to move the box down.
