Settings, action bars, graphics and key bindings can by done through simply copying the character's settings files in their respective WTF folders.

Internal addon options/configs can *sometimes* be sync'd by copying the addon LUA but most of them store the character settings in separate subsections per server/character, which makes it painful to migrate. That said, most of those can export their profile for use elsewhere.

There's no easy way to do all that in a few minutes, though.
