Doing the clean up will also depend on how mission critical the stuff you are unplugging is. I was able to do one of our switch racks in about 2 hours becasue I just ripped everything out and started from scratch becasue it was for 3 floors of an office building and it was after hours so no one was online. It took me equal amount of time to do our servers becasue the down time for those had to be minimal and i had to trace each wire, and do one at a time rather than starting from scrath. After the initial wiring it tooki about 15 minutes to tie eveything up and make the proper cuts in the raceways to make them all pretty lol.
