Joomla 1.5 to Joomla 3.3 Website Migration
Security and technical support for Joomla 1.5 has ended in September 2012. It does not mean that your website will stop working. Only that your website will now be susceptible for hacking or being compromised.
Joomla is not providing any security patches for Joomla 1.5.
Extensions for Joomla 1.5 are not supported any more. Thus, if hackers find vulnerabilities with an extension, they can compromise your website.
Since the extensions for Joomla 1.5 are not being supported, it means that they are not improved. Some extensions might even stop working.
Web hosting providers are upgrading PHP, an essential part for Joomla web hosting to PHP 5.4 or 5.5. Your Joomla website might stop work or bring up lots errors one day.
There have been instances where web hosting providers have shut down Joomla 1.5 websites.
Since your website is an essential part of your business, you do not want your clients or visitors see a hacked website or a website that throws up hundreds of errors. It can result in lost revenue.
