PART 1: MANUAL UPDATE
In WordPress 2.7.x you can update your application manually simply by using admin area. Whenever a new version is available, you will get a notification in the WP admin area. Before proceeding with the upgraded version, it is better to make a backup of your WordPress.
When you are ready to update, click on Please update now button. You can choose whether to upgrade manually or automatically on the next page.
This tutorial will cover both of the procedures. Part 1 will cover manual update process and Part will cover the automatic update process.
5 Simple Steps for Manual Update of WordPress
From the plugin management page, deactivate all the Plugins that you use. You will find some plugins might not work with the updated WordPress version. In order to avoid incongruities, it is better to deactivate all plugins. This will make sure that you won’t finish up with an upgraded, but the broken installation of WordPress after the upgrade process.
Backup the Database Tables and Files
It is better to keep backup database tables and files including .htaccess. For further instructions, please visit our wordpress backup tutorial.
You can overwrite your WordPress files by two ways.
- After downloading the latest WordPress version from the WordPress download page, upload it to the WordPress directory. Then overwrite all the files that exist there. In this way, you can preserve your images and themes.
- Delete your old files and upload the latest files from the new version you’ve downloaded.
If you cannot understand that which option is better for you, then the following suggestion is for you.
According to my opinion, it is better to delete whatever is possible. Since the uploading (or upgrading through cPanel) process may not overwrite an existing file properly, it may create problems later.
Running the Upgrade Script
To run the upgrade script, visit your blog’s Upgrade Page (http://yourdomainname.com/wp-admin/upgrade.php) and after that follow the commands that are displayed.
Plugins Reactivation One by One
Go to the Plugin Management Page and activate your plug-ins one by one. Make it sure that everything is working properly. If any plugin does not function properly, deactivate it. You also can contact with the plugin author to encourage him / her to upgrade the plugin.
