How to upgrade joomla 1.5 to 2.5Written by James Richardson
Recently there has been a large increase in security issues with Joomla 1.5. Joomla 1.5 was first released in January 22nd 2008 which ended in its development in Joomla! 1.5.26 in March 27th 2012. Joomla documentation states, "Joomla! 2.5 is the current LTS (Long Term Support) version. The previous LTS version, Joomla 1.5, is still widely used and will be supported with security fixes only until September 2012." (Click here for more information)
IMPORTANT!! If you are running Joomla 1.5 you will need to upgrade. You will also need to completely remove and delete any components that are not being used anymore. For example, the "dvmessages" plugin. The "dvmessages" plugin is not compatible with anything past 1.X; So, when you upgrade from 1.5 to 2.5, the files are just left in place, and your site can still get hacked causing outbound DDOS Attack.
