Moving files from local to S3

I've got a church site which has become extremely bloated with years worth of sermons stored on the local server. We're redesigning the site and taking this opportunity to move the files to Amazon storage. Is there a way to automate (or simplify) the process of updating links for the files, or do we need to go through the sermons individually and pick the new references on Amazon?

If you know a bit about databases, you can change the path to the files directly in the database table (the #__sermon_sermons table).
Or you can do an table export, edit it locally in your preferred software (Excel, Notepad++, …) and import it again.
That's by far the most convenient way to do it.

Perfect, that'll work. Thanks!
