Not knowing how you do it, I have no idea if it is common knowledge. Also, you want lots of air after the boil, but none after fermentation - I assume that's what you meant, but it's not what you typed.
If I was trying to rack with absolutely no air exposure, I would fill a keg with sanitizer and push it out with CO2. Then I would put a carboy cap on the carboy, with a racking cane and hose leading to a liquid corny fitting. Hook the corny fitting up to the liquid post of the keg, hook CO2 up to the other hole on the carboy cap, vent the keg through the PRV, and turn on the gas just enough to push the beer from the carboy to the keg. If you wanted to be extra anal you could split the gas and hook the CO2 up to the gas post on the keg too, but that's really overkill.
How did you do it?
