This page contains informations you need to upgrade an existing phpMyAdmin installation.
 General guidelines
- Download the latest phpMyAdmin version from http://www.phpmyadmin.net/home_page/downloads.php or http://sourceforge.net/project/showfiles.php?group_id=23067
 Specific Steps - Windows Example
- Back up your current phpMyAdmin directory.
- Download the desired version and extract its files to a temporary location, e.g. C:\NEWPHP\.
- Locate your current config.inc.php file. This will be the one in your phpMyAdmin directory, NOT phpMyAdmin\libraries\config.default.php!
- Copy your current config.inc.php into the temporary directory containing the extracted files (e.g. C:\NEWPHP\).
- Delete the contents of your phpMyAdmin directory (assuming you backed it up. If you didn't back it up, then go back to step 1, do not pass "GO," and do not collect $200!).
- Move all of the contents of your temporary directory (e.g. C:\NEWPHP\) into your original phpMyAdmin directory and empty your browser cache.
- If successful, announce "I'm a genius!" to everyone within earshot.
- Does not work with WAMP ver 2.0 with phpmyadmin 2.11.6
 Specific version notes
When upgrading from versions prior to:
Requires PHP 5.2+
- config.inc.php no longer holds every configuration directive; only directives that differ from those in libraries/config.default.php are needed here. See the Quick Install section for more details.
Since version 2.6.0, simply copy your existing config.inc.php to the new directory. You may wish to read the release notes so you can take advantage of any new features. Some people had problems with this method though.
