Domain mapping only changes the root domain of the article in question. It does not search through all of your posts and find any old links that you may have written or edited into those posts that include something like yourolddomain.wordpress.com and then change those links to yournewdomain.com . That is not what mapping does.
However, there is a great plugin that can be used to achieve this same result.
before you use it, make absolutely certain that you 1 back up your database and 2 know how to restore it before using this plugin.
If you break your website using this plugin due to lack of understanding, it may not be fixable without a good backup.
If you are unsure, hire someone that knows how to do these things! 🙂
In the right hands this search and replace plugin is awesome. In the wrong hands, it is very dangerous.
