NOTES ON RUNNING UPGRADE SCRIPTS

Upgrade scripts are located in <ensemble_directory>/install/upgrade_scripts

Before running any upgrade script, make sure to read the release notes for the
corresponding version. The release notes may provide important details on
the changes that the upgrade scripts peform.

PROCEDURE

1) IMPORTANT: back up your database and Ensemble web directory before 
   running any upgrade scripts. The upgrade scripts generally
   perform database backups themselves. However, you never know when
   something can go wrong.

2) Locate the appropriate upgrade script for your version. See the release
   notes for the filename of the script. The format of upgrade scripts is 
   generally "upgrade_<version>_<date>.php"

3) Make sure you can run PHP on the command line. This is done by typing
   the following at the command line:
	php -v
   If you see a PHP version number instead of an error, then PHP is working
   on the command line.

4) Go to the directory <ensemble_directory>/install/upgrade_scripts and type:
	php -f <upgrade_script_name>
