I want to try and do it myself. The patch panel is in a closet located in the middle of my house. Figure I can tie one end of the cat6a to the wall jack side of the cat5e and pull it all the way through from the patch panel. Would it be that easy?
If they didn’t staple the existing runs, pretty easy, just disconnect one end, tie some nylon pullstring to it, and pull the opposite side through until you reach the string. Then simply tie it to the new cable and reverse the process.
If they stapled the existing runs, then damn near impossible without ripping some walls open.
E. I would strongly advise against tying the cables directly together. You risk damaging both cables and the knot is much much larger that way, meaning you’re likely to get stuck somewhere. Also I can’t describe how defeating it is to wrestle with a cable for two hours only to realize it was damaged in the process when you finally get it though.
