How to Upgrade Joomla 1.5 to Joomla 2.5: Tutorial

Generally, changing from an older to the newer version of software is called “upgrade” and is a rather simple process. However, Joomla CMS has so severe distinctions between its existing versions, that there’s no mechanism available to upgrade between the major versions (1.5 to 2.5 or 1.5 to 3.0).

This is why upgrading your Joomla 1.5 to 2.5 is actually the migration, because it involves moving files, plugins, template etc to the new website.

There exist three basic ways of migration between major Joomla versions:

  • start from scratch – it means, you have set up Joomla 2.5. website and manually move all the content from 1.5 site.
  • convert website using third party extension – it will shorten and ease the process of migration.
  • migrate using an automated online service – which means no plugin installations, no manual data transfer. The process is very simple and speedy.
