How to upgrade my existing Joomla 1.0.x to 1.5
Detailed information on how to upgrade your existing Joomla 1.0.x to 1.5 can be found in our Joomla 1.5 tutorial.
Please note that the Joomla upgrade to 1.5 will preserve ONLY the content of your current web site. No custom templates or modifications will be stored. No components, modules or mambots you have installed will be available after the upgrade. You will have to add again all custom components as you did before and only if they are available for the new Joomla version.
Joomla is a powerful software that is easy to work with once you have the right host to support you. Before you lose any more time with the wrong host, check out the SiteGround Joomla hosting offer.
