I just upgraded from 2002 to 2005 and noticed the warning screen to not customize the standard acad.mnu file but to use the new partial menu custom.mnu instead. I tried to use the migration tool porter figuring that that would accomplish this, but it doesn't seem to work, (what a lame help file for that one). I ended up just copying my custom tool bar menus and bmps over to the new support sub-directories and then loading the various menus. All seems well, but I still want to know where in the documentation is the proper use of this custom.mnu explained, and what kind of doo are we in next upgrade if we ignore it? Thanks in advance.
