I would not be majorly concerned about mixing coolant. You can be if you want, but after doing the same (mixing coolants) and doing a LOT of research you'll basically find that todays modern coolants can generally mix with anything. Not that I'd suggest leaving it that way - just because I'm a bit paranoid about it still - and recommend a flush and fill. You can do it yourself. Basically you need about 10-15 gallons of distilled water as you'll need to dump the coolant (two hoses), fill it, burp it, fill it to the top again and repeat the series of steps about three times. Then you can dump it again and add the Porsche coolant.
If you haven't done so already, join the PCA, then check with your local Porsche dealer for parts. You'll get a 15% (or more) discount on parts. The coolant I bought was unmixed at $42 a gallon. Cheaper than any mail order. Including Suncoast. Takes three gallons for a complete fill. Personally, if you are going to go this route I'd suggest you consider looking at your hoses, pump, and a low temperature thermostat too. If the car has enough miles (my OEM pump died at about 72K). At that time I replaced the pump, hoses, thermostat and used the uView Airlift 550000 vacume fill system. The uView is much easier to sue than burping the motor to fill it. Highly recommend it.
