Happen to have access to one of those very old 2.7's ...sigh ... been asking owner at least once a month if it's time to upgrade yet! :\
Server to which I have access uses MySQL as DB ... not Oracle.
When accessing, these warnings:
Search and replace text throughout the whole database
This script is not supported, always make complete backup before proceeding!
This operation can not be reverted!
Several tables are not updated as part of the text replacement. These include configuration, log, events, and session tables.
If you have need of the tool, might be best to use older methods via command line ... sed or a text editor that can do S&R on an sql dump of DB.
Please see:

Quick and Hacky method
Replace any links in the database that contain the full site URL:
#sed -e 's/oldserver.com/newserver.com/g' oldmysqldump.sql > newmysqldump.sql
