Blog,CMS Platforms Reviews,Joomla!

Generally, switching across an older and newer versions of software is called “upgrading” and it is a rather simple process. However, Joomla CMS has so severe distinctions between its 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 from Joomla 1.5 to 2.5 is actually the migration, because it involves moving files, plugins, templates, etc. to the new website. There are three basic ways of how to migrate from Joomla 1.5 to 2.5s:

  • start from scratch – it means, you have to set up Joomla 2.5 website and manually move all the content from the old 1.5 site to new 2.5.
  • convert website using third party extension – it shortens and simplifies 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.
