Skyrim SE - moving Arc Cyrae lower entrance to another close by spot part 1

Started this video several minutes into me starting this project, but is not much, just had already moved copies of the tower entry and door, the rest will happen in this video and the ones following it. Note: This could be boring for some as I do take quite a long time to decide how I want things when I move dungeon entrances, nearly 2 hours altogether before I am finished, and yet still have to go into sseedit after all this to make the patch. And I still need to figure out why Arvyel won't talk, I messed on something somewhere, it happens, not my mod so trying to fix things sometimes means learning some new things too. But for now, must stay focused, my patch to move this lower dungeon entry.
