What is the best module for redirection

I created a vocabulary called Language and a term within this language like

Visual Basic
.NET
PHP
JAVA

The path alias for the node if I select .NET term is for ex.

http://www.sourcecodester.com/net/hotel-reservation-system-vbnet.html

Now I decided to change ".NET" term to "Visual Basic .NET" and I'm planning to update all the path aliases to the new term which is "Visual Basic .NET". But this would make a problem from any website that has a backlink to every page that I'm going to change. A page cannot be found will occur because the new URL would become:

http://www.sourcecodester.com/visual-basic-net/hotel-reservation-system-...

I search drupal for the redirect module and I found these two module:

http://drupal.org/project/taxonomy_redirect
http://drupal.org/project/bouncer

I just do not if this can help or is there any other module that can solve my problem.
