I maintain about 30 different installations of WordPress on a few accounts at Dreamhost. I'd like to be able to update all of these installations at the same time.
The closest script I can find is called WP Mass Upgrade. These scripts are optimized for WHM/cPanel systems, but with slight modifications should work for Dreamhost and other systems.
First, is this the best method of multiple upgrades at once? If not, could someone help me? I don't have any subversion experience and have no clue how to run the script in the WP Mass Upgrade link.
I believe Dreamhost support subversion and so I'd really appreciate detailed instructions if anyone could be so kind.
