RE: Updating from Emacs 23.3.1 to 25.3

I know I have to do that, I just think I need someone here with me to walk
me thru it. I already have 25.3 on my computer, in an Emacs1 directory, but
the directory structure is so different, I have so much in my .emacs, and I
need updated versions of many of the procedures and am not sure where to get
them all. That is why I specified where I live in this username (near
Harrisburg, PA). I have tried local computer shops, but nobody is that
familiar with Emacs.
