# Upgrading multiple, individual WordPress installations

 * 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](http://birdhouse.org/software/2007/07/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](http://gondwanaland.com/mlog/2008/08/31/webapp-deployment/)
   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.

 * I personally would like to find a way to do it without subversion as there are
   just to many different installs on two many different hosts that I manage. This
   really should be easy to create a plugin that simply uses WP’s internal upgrade
   options.

 * I think a non-subversion option to upgrade would be amazing as well. I am in 
   the same boat as you, MACscr.
 * If there was a way to trigger the upgrade script on each blog all in one shot,
   it’d make life so much better. One major problem, however, would be the slow 
   connection speed of opening up simultaneous ftp or ssh connections at once then
   running multiple simultaneous upgrades on one server.
 * The whole thing would have to be more than just a plugin, however, because that
   still means you log into each WP installation and upgrade individually.
