Rewrite rule to change directories

[rover]

Hi. I can't seem to produce a rewrite rule for an .htaccess file in the directory_original directory that will allow me to redirect the following url:

domain.com/directory_original/run.cgi?ID=23&cat=19

to:

domain.com/directory_new/run.cgi?ID=23&cat=19

Does anyone know how that could be done?

Thanks very much, I'll check that out.

Actually I had success changing the paths to a pretty large site by having the following simple redirect in .htaccess

Options +FollowSymLinks
redirect 301 /directory_original/ [domain.com...]

I have used the above on other servers also that do not require the "Options +FollowSymLinks" as this was already set in the master .htaccess of the hosting account.

Edited: just wanted to add this only will work of course if the files are of the same name in both the new and old directory/path.
I have also experienced some servers that need to have the trailing slashes removed to accomplish the same thing:
redirect 301 /directory_original [domain.com...]
