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.
To upgrade from version 1.6.x to Joomla 1.7 please follow this guide

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.
With the 1.7.0 to 1.7.1 upgrade, there are some database changes that need to be made.
If you use one of these manual methods to copy the files, you also need to manually update your site's database. To do so locate the six files beginning with 1.7.1 in the folder /administrator/components/com_admin/sql/updates/mysql.
Inside these files you will find parts like
#__categories. Replace the pound sign and the first underscore (
#_) with your database tables prefix. By default this is
jos. If you didn't get the prefix before starting, open your site's configuration.php and search for
$dbprefix. The string inside the single quotes behind it is what you're looking for. So you need to change
jos_languages and so on.
Once you've done this go to your site's phpmyadmin (or any way you usually manage your database) and open the database your site uses. There will be a tab called SQL, open this. Paste the content of your modified sql files inside the text area and press go.
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.

|Using an FTP client to upload files|
|Using a terminal session|
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.
