You have to carefully flush out all the hoses, evaporator, and condenser
with solvent. Remove the compressor, drain it thoroughly, then fill with
the specified amount of ester oil. It's not really too hard, when I
converted mine it took an afternoon.

If you replace the compressor, make sure it comes with ester oil in it,
many times it will come with PAG oil which you have to drain and refill.
The Volvo conversion kit comes with a bottle of oil.
