You can create a file with all your domains

cd /path_to_domain/scj/admin; env HTTP_HOST=yourdomain.com php update.php 
cd /path_to_domain2/scj/admin; env HTTP_HOST=yourdomain2.com php update.php 

and so on and run it in SSH

sh update.sh

This way you can update all domains at once.

Note: update script doesn't overwrite index.php or any other files at the root of your domain. So you have to copy index.php (if you use it). If you don't want to do it each time you have 2 options:

1. add to update.sh something like “cp ../cgi/index.php ../../index.php ”
2. or create a symlink to original scj/cgi/index.php

There's no built-in update rollback. The only chance is if you have created backup. Note, if you just restored mysql db - it won't help caz you still have the same files.
