Domain mapping - should we make additional changes in Site Admin?

I have used Donncha's plugin for more than a year, and recently switched over to the WPMUDev Premium version.

A year ago, I saw in a few blog posts where they recommended making changes to a mapped blog's backend (Site Admin > Blogs > Edit) to basically rename any instance of to the mapped version (, for example).

In , I find these fields:

Blog info (wp_blogs) -> Domain ->
Blog Options (wp_4_options) -> Siteurl ->
Blog Options (wp_4_options) -> Home ->
Blog Options (wp_4_options) -> Fileupload Url ->

QUESTION: Should they be all renamed to or left as is?
