Upgrading from an existing version

From Joomla! Documentation

Revision as of 18:39, 7 March 2011 by Dextercowley (Talk | contribs)

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.

Here are the detailed instructions.

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.

  • Alternative 1: Unpack the package file on your local computer then use an FTP client to upload them to your site.
  • 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.
  • 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.

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.
