4630 AC Question

Bought a 4630 today and the seller said the AC compressor is seized. Replacing that is no big deal, but what is necessary to convert this to 134a refrigerant?
 

You'll need to flush system,install new compressor with correct amt of pag oil,receiver/dryer & expansion valve then evacuate well. I've read where one needs to replace all hoses but my 4255 with 134A operates fine with nearly all original hoses.
