wait until spring. They made it for ten yrs w/o your help, they will wait until spring. This will enable the bees to fix what you break w/ new reasources. If you do it now, and a mistake occurs, they cant fix it. They cant make honey, collect pollen raise a new queen brood etc. Then do waht MB says. Take your time, break hive into individual components and decide on a frame by frame basis on whether it can be saved, or needs to be cut and rubberbanded into a new frame. It seems overwhelming now, but by taking a frame by frame methodolgy, it will be easier than you imagine. Big jobs are always easier when you make them into little jobs. Good luck.
