Follow along as I migrate a site from Joomla 1.5 to Joomla 2.5. Although there is no all-in-one solution to migrate your site (and rightfully so, as Joomla 1.5 and 2.5 are completely different systems), there is a great tool out there for importing your content into 2.5. Content, as in your articles, categories, images and authors.
J2XML is the perfect component for exporting and importing your content. Its actually two separate components. The process is simple. First install the J2XML Exporter on your Joomla 1.5 site. This allows you to export your articles or entire categories, including images and authors, into an XML file. Then, install the J2XML Importer on your Joomla 2.5 site to simply import the XML file. That's it! J2XML will create the categories, images, users/authors and all other info associated with the articles you exported.
Among it's powerful features, the J2XML Importer allows you to maintain content ID's. This is extremely helpful in terms of SEO, since Joomla includes content ID's in your site's URLs. Most likely, the search engines have already indexed the URLs of your Joomla 1.5 site. So making sure the content ID's remain unchanged ensures that your URL index will remain intact, with minimal dead ends or 404 "Page Not Found" errors.
Overall, J2XML is a solid solution for helping you migrate to Joomla 2.5. A big Thank You and two thumbs up to Helios Ciancio and the folks at http://www.eshiol.it/ for making such a useful tool!
