Updating from an existing version
From Joomla! Documentation
Revision as of 12:18, 17 April 2011 by Dextercowley
It is recommended that you back up your site before upgrading to a new version. That way, if something goes wrong during the upgrade process, you can easily restore your site to the earlier version. Also, it is a good idea to review the release notes for the new version to be familiar with what was changed.
Starting with version 1.6, there is a new option for upgrading your site from within Joomla. The old method of upgrading from an archive file still works as well. Both methods are documented here.
Simple Upgrade from Joomla Extension Manager
Step 1: Make sure you have a current backup of your site
Step 2: Find and install uppdates
- In the back end of your Joomla site, navigate to Extensions → Extension Manager and open the Update tab.
- Click on the Purge Cache icon to clear out the cache.
- Click on the Find Updates icon in the toolbar. If there is an available update, the screen will list it, similar to the screen shown below.
- Select the update (using the checkbox) and click on the Update icon in the toolbar.
- IMPORTANT: This process will take a few minutes. Wait until the process completes and the success message shows, similar to the screen shown below.
- Congratulations! At this point, your site is updated. Check that your site is working correctly. If you have any questions before, during, or after the upgrade then please ask them on the Joomla! 1.6 Migrating and Upgrading Forum.
Manual Unpack Archive Method
Step 1: Download the upgrade file
To download the most recent patch package and to obtain the MD5 hash:
- Proceed to the Joomla Download page.
- Click the "Download other Joomla 1.6.x packages" link
- Click the "Joomla1.6.XUpdates" link under the "Packages" heading to go to the detail page about the current package
- Click the "Files" tab to view the various patch files.
- Locate the row that matches your current installation version and patch package (zip, tar.gz and tar.bz2) that is most convenient for you.
If you have questions about these instructions, read the Additional Information below this table.

Step 2: Backup your site
Before you actually upgrade, you really should make a backup of your site. Backup your existing Joomla site files and store all the files and database in case something gets messed up, you wont have any problem reverting back.
All upgrades should be first tested on a copy of your site before being applied to a live site.
Step 3: Install the upgrade file
There are different ways of installing a package file depending on your particular circumstances. If you have difficulty with one of these methods, then simply try another.
|Unpacking a package file|
- Alternative 1: Unpack the package file on your local computer then use an FTP client to upload them to your site.
|Using an FTP client to upload files|
- Alternative 2: Use an FTP client to upload the package to your site, then use a terminal session (eg. SSH) to connect to your site and unpack the files there.
|Using a terminal session|
- Alternative 3: If your hosting provider gives you access to your site via some sort of web control panel like CPanel or Plesk, you can use the control panel file manager to upload the package, then use a terminal session (which might also be available via the control panel) to unpack the package file and overwrite all changed files on the server.
- If you are using CPanel, there is specific information on Uploading and extracting an archive file with CPanel.
Step 4: Check your live site to make sure it is working correctly
Don't assume that the upgrade will work flawlessly just because the test upgrade worked. Check to make sure that nothing untoward has happened. It could be that differences between the live site and test site platforms will bring out a problem that you did not notice during testing. If you find a problem and it cannot be resolved quickly you might have to rollback the upgrade using the backup copy you created in step 2.
Hopefully all will be well and you can relax. If you have any questions before, during, or after the upgrade then please ask them on the Joomla! 1.6 Migrating and Upgrading Forum.
