Window removal

Just bought a door and the windows are down. I need to get the lock out and switch it with my original door. To move the window should i follow the steps in the DIY article ? or do i just remove the stoppers and bottom mounting bolts? or should i just bolt it on the car and raise the window up. the thing is the door has to get re painted so i would have to put it on and take off again.

i’ve nvr removed our doors before, but if u removed the current one, couldn’t u get the newer one close enough so that u can hook up the connecters without installing it in fully? would require someone to either hold the door or connect the stuff and turn the car on, and lift the switch. either way good luck.
