I faced a similar problem recently. Links on the site were mixed case and I wanted everything to be lowercase. I did this in two steps. I would suggest this approach (you can research this a bit more if you'd like). I added the following to my httpd.conf file:
RewriteMap lc int:tolower
The second step involved changing the hard coded links on the site, for that I used MySQL's REPLACE command. I was able to convert about 10,000 internal links in about five minutes. I can provide an example if you'd like.
