Minimum transfer time in Kunming Airport

I had previously bought an international flight departing KM at 10:40am a month ago. I may be purchasing a domestic flight arriving in KM at 8:55am instead of taking a train to KM. As they are separate itineraries purchased from two different airlines, would they transfer my luggage all the way through to final destination? Also, would there be enough time for transfer from domestic to international hall with 1hr 45min?
