Yes, correct as above.
Also, make all beer transfers under CO2.
I use 7.5 gallon glass "acid carboy" fermentors with "acid carboy caps", you know the maroon colored ones with two spouts sticking straight up. Purge all lines/racking cane with CO2. Stick the racking tube in the center spout with plastic tubing connected to the keg "out" port. Stick the CO2 into the second spout of the carboy cap. About 4-5 psi CO2 and the beer will flow out the fermentor into the keg, which already has a CO2 layer as described above. This is a solid beer transfer under CO2.
