I tried another tool in that folder called "republish.php" using the following SSH command:
php /home/********/public_html/scripts/maintenance/tools/republish.php www.******.com '2014-08-01 04:00:00' '2014-10-01 23:59:59'
And it did exactly what I needed! Processed the 1mil+ records in a few minutes and all stats are reporting as usual.
A bit disappointed I had to dig around for so long to find this solution, rather than having some info/documentation about these tools or giving helpful responses on the forums, but I hope this solution helps someone else in the future.
