Need help extracting a large number (8-25k) of files from older SDL (11.1)

Hi all from an SDL novice - my group needs to extract a large number of files (up to 25k) out of SDL (and older version, I believe 11.1?) so that it can be placed on an FTP server. We have a tight timeline and budget and don't know of a script or quick way to extract more than a small number at a time (maybe 20 files?) manually.

Does anyone have any experience with this or know of a script that can be used? Any help or input is appreciated. Thanks
