The final part of the Upgrade to Joomla 3 is to remove some of the old Joomla 2.5 templates that are no longer being used. If you go to the Extensions menu and select Extension Manager and then select Manage. This is the list of all the parts of Joomla that are installed and we need to filter that list by Type to just show the templates. You can see here in the Version column the templates that we need to remove and they are all marked 2.5. They are Atomic, Beez five, Beez twenty and Bluestork. Just those four have come up from the previous Joomla 2.5 site and we can uninstall them now because the are not going to be used in our new Joomla 3 web site. So once you have selected those four templates click on the Uninstall button to remove them. They have now been removed and our site is ready to go and we are ready to take advantage of all the new features available in Joomla 3.
