Your chain rings and chain will be worn according to the chain line on your old bike.
Any variation to the chainline on a worn setup - such as moving it to a new bike - will increase the chance of chain suck as the wear angle isn't the same.
Hence, replace your chain rings, and ideally your chain and cassette also.
Having said that, for the first time in three winters I've been getting chain suck with my Hammerschmidt set up, but it is exacerbated by the usual causes, mud and crap and running on small cogs at the back rather than changing up at the front.
This time of year, keeping the rear mech tensioned by being in the lower rear gears is always advisable, as well as cleaning the bloody chain which of course I don't since I'm out on it every day before work and when I get back and it's cold and dark both ends of the day so the bike only gets a clean once a week if it's lucky.
