Upgrade Joomla 1.5 to Joomla 2.5
Again, Joomla.org provides excellent instructions and Migrator software for this upgrade:
Below are steps describing the process:
- Read all the instructions in the Joomla Migration document.
- From the Joomla 1.5 administration screen, install jUpgrade in the Joomla 1.5 site. There is a link to it in the Joomla 1.5 to 2.5 migration doc.
- Enable the Mootools Upgrade plugin. If it’s not already installed, you can download it from the Joomla Extensions directory.
- Run the jUgrade extension. Once you successfully run it, it will download and install the lastest version of Joomla in a sub directory and migrate the 1.5 Joomla content to it.
Once jUpgrade is finished, check the new site to make sure you content migrated successfully. The Joomla migration document provides detailed instructions on how to move the 2.5 site to your live site once you are finished.
