Cold crashing yeast

I racked some fermented beer to a keg to cold crash the yeast (US-05).

Is it necessary to rack again to a serving keg?

What if I want to force carbonate using the shake method? Seems like the shaking would put the yeast back in suspension.

Thanks for your advise.

It would be a good idea to rack into a serving keg, especially if you're going to shake the keg to force carb. You can push the beer from one keg to the other by running a beer line between the beer out posts on each keg. Pressurize the receiving keg then remove the gas, hook up the beer line, and then slowly vent the keg to keep the beer flowing. Once all the beer is out of the crashed keg, you can put the receiving keg on gas and carbonate.

+1 on Moonshaes' method- I do this quite often. Uses a lil bit more CO2, but no contamination to worry about
