Also, your house may be lacking wall insulation to avoid overheating the old wiring. This can checked by looking at your heating bills.
You could check if the remaining old wire is even carrying power. If it does, finding the source and routing for the neutral and hot conductors can be challenging.
heating bill was insane, so we put in a wood burner last spring for this winter. while putting the wood burner it we confirmed that the walls arent insulated, just some sort of plaster crap with wooden slats coverng the studs then brick.
some of the knob and tube is definatly still carrying power, all the outlets in areas like hallways and in a couple of rooms still have knob and tube behind them, attic lights and outlets are all knob and tube and who knows what else. im only going to mess with it on an as needed basis untill i can afford to have someone come and replace it all in the next year or two.
