For some basic information on patching and migrating, see [[Upgrading and Migrating FAQs]] and [[Upgrade Instructions]].

You can also use a Joomla! extension to automate the process of loading version updates. See [http://extensions.joomla.org/extensions/core-enhancements/installers/9332 Update Manager for Joomla!] for more information. 

Review the release notes for the new version.

When upgrading from a version that is not the most recent, review [http://www.joomla.org/announcements/release-news release notes for the prior releases.]

==Step 1: Download the upgrade file==

To download the most recent patch package and to obtain the MD5 hash:

* Proceed to the [http://www.joomla.org/download.html Joomla Download] page.
* Locate the row that matches your current installation version. 
* On that row, select the patch package (zip, tar.gz and tar.bz2) that is most convenient for you. 
* Verify the download using the MD5 hash listed in the right column on the same line as the package you selected.

To find the MD5 hash:

# On the [http://www.joomla.org/download.html Joomla Download] page, click on "Download other Joomla 1.5.x packages"

# Click on the bold text in 'Release Name' column. For example, if you want to find the hash for 1.5.9 to 1.5.10 patch, click on 'Joomla1.5.10updates'.

# On the next screen click on the 'Files' tab, where you will see the hash for each package.

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==

==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 [http://forum.joomla.org/index.php/board,430.0.html Joomla! 1.5 Migrating and Upgrading Forum].
