efore Upgrading

Don't let the numerical closeness of 1.5 and 1.6, mislead you. Joomla 1.6 took three years to develop and has been a major undertaking. Countless hours have been spent by many volunteers from around the world to put it all together. Although much of the code is the same from Joomla 1.5, much of it has been written from the ground up, and the changes are comparable to the changes from Joomla 1.0 to 1.5. Because the changes from Joomla 1.5 to 1.6 are so large and because of the massive effort put into getting Joomla 1.6 to where it is today, there is no core upgrade path, this is indeed a migration. In planned future releases of Joomla (which will be released every 6 months), such as Joomla 1.7, 1.8, etc, the changes from version to version will be more incremental and a core upgrade path is planned. Now that Joomla 1.6 is finally here and stable, a community initiative led by the developers of Joomla is turning towards jUpgrade (a 3rd party Joomla extension on the JED originally developed by Matias Aguirre) for help and to help. Many of Joomla's developers (who are all volunteers that freely contribute their time) are volunteering to put the finishing touches on jUpgrade.

jUpgrade allows you to migrate from Joomla 1.5 to 1.6. Lets get started!

 

Review the Requirements

Please, please save yourself (and possibly your clients) a lot of headaches and make sure that your server (and in the case of jUpgrade, your browser too) is up for the task. please review thetechnical requirements for Joomla! 1.6. Please review the requirements for jUpgrade as well.

 

Before You Get Started

Before you get started, there are a few things that you are going to have to check and/or think about:

  1. Is your Joomla 1.5 version up to date? At the time of the writing of this tutorial the most up-to-date version of Joomla 1.5 is 1.5.22. Much of the testing of the migration has been done from Joomla 1.5.22 to Joomla 1.6. If your version is not up-to-date you should probably upgrade to 1.5.22 before migrating, especially if you are running Joomla 1.5.11 or lower.
  2. Do all your extensions have Joomla 1.6 native versions? At the time of the writing of this tutorial there are 108 available on the JED. Please note that jUpgrade is not currently able to upgrade Joomla 3rd party extensions, so those will have to be done via their respective upgrade procedures. This is however a work in progress.
  3. Have you modified any core files? Any changes that you have made to core files in Joomla will be lost so please be forewarned.
  4. Is there a Joomla 1.6 compatible template available from your template provider? If not, do you feel comfortable making the changes yourself? There are a couple good resources:
    1. Chad Windnagle's Joomla Community blog
    2. Chris Davenport's "Template Changes for Joomla 1.6" presentation
    3. Joomla's Docs Template Tutorial Please note that although jUpgrade is not able to currently upgrade templates, the developers are working hard at implementing the feature.
  5. Is your language pack available in Joomla 1.6? Find your Joomla1 1.6 Translation.
  6. Do you have folder or file permissions issues in your Joomla 1.5 installation?
  7. Do you NEED to migrate to Joomla 1.6? Joomla 1.5 is powerful and very mature. For many people there is not a need to rush into Joomla 1.6. Joomla will continue to support Joomla 1.5 for at least another year and three months, releasing security updates and bug squashing updates when needed.

The two main features of Joomla 1.6 that makes it superior to Joomla 1.5 are: Access Control List (ACL) and nested categories. Gone are the days of simply having guests, registered users, authors, and editors, without being able to specify what they can and can't do in the frontend. Also, with 1.6 you can have more flexibility of organizing (and therefore displaying) your content with nicely organized categories within categories. No more being restricted to the section >> category structure. Those are all great things to have (especially the ACL), however, for many 1.5 users, it isn't needed. The main point is to decide for yourself:
