using updates
=============================================
Here are the steps:

=============================================
1) Copy the files to the following locations:
=============================================

	controllers/update.php
	application/config/updates.php
	install/update.mysql-3.0-3.1.php
	
=============================================
2) Maintenance Mode
=============================================
	To use the update script, you must put site in maintenance mode
	by adding the following config line to application/config/config.php file:


	$config['maintenance_mode']=1;

	
	Note: You must remove or change the value once you are done with the updates. 

=============================================
3) Run updates
=============================================
	
	Open the URL: 
	<yournada>/index.php/update
	
	This page will list any available updates that might be available for your DB.
	Please note the script doest not check/know what version of NADA you are running
	so make sure you pick the right update.
	
	The script will show each update listed on the page.
	
	Green boxes=Success
	Red boxes= Failed
	
	With each update status, you will see the actual SQL that was executed by the script,
	for RED entries you will need to manually execute them using a database utility such as PHPMYADMIN, MS-Enterprise Manager etc.
	
	Important! Also Make sure when you run the updates, the database user has enough rights to modify tables and indexes.

=============================================	
4) 	Verify Changes
=============================================

	Visit the site and see if you notice any issues such as database errors etc.
