Don't degas the keg! And don't siphon it.
You can jump it to a new keg even easier.
You'll have to release the pressure, unscrew the "out" post, and then put a sanitized nylon or hops bag over the long diptube. Put it back down in there and tighten. That will screen out the hops debris.
Get two black QDs and put them on a length of beer line. Put one on the new keg, on the "out" post. Put the other on the original keg. Keep the gas on the first keg (but turn it down to about 3-5 psi), and pull the pressure relief valve on the receiving keg. The beer should flow. Keep pulling the pressure relief valve on the receiving keg until it's finished transferring. No chance of oxidizing the beer and you can transfer carbed beer without any issues.
