how do i change all my links?

I'm modifiying a site built by somebody else. I'm basically just putting up a new page, & I need to re-direct the old links to this new page.
There are approximately 40 separate pages on the site, & they each contain the old link that I'd like to update.

Is there a way to automate this process, so I don't have to go change the HTML in each individual page?
(Other info is available, if needed.)

thanks in advance....

Sure there is a way (e.g. login over SSH and perform a search & replace in the files on the command line), but that is not related to / possible with FTP at all.

...so...is there a way that IS related to FTP?

Or does anybody have any alternative advice?
I'm pretty new to this stuff, I'm behind a deadline, & I just need the simple solution.
thanks
