Tutorial : How to update to Wordpress 2.5 in just four steps
To get you started, I’d suggest getting all of the below plug-ins to make sure everything will run smoothly.
When you’re going to upgrade your Wordpress installation, your visitors will see a 404 Error page not found. By using this plug-in, you’re making sure they’ll not see that message, but a custom one defined by you.
2) WP-DBmanager
Before even starting to upgrade your installation, remember to back-up everything you need. This is just a safety precaution you should take, for the sake of your data.
3) Wordpress Upgrade Preflight Check
It does a quick check to see if your current plug-ins could create any incompatibility issues with your upgraded installation. If you get an error message for a specific plug-in, contact the author of the plug-in directly to make sure everything is fine. If the plug-in is not that important, simply deactivate it.
4) The Instant Upgrade plugin for WordPress
Install and activate the plug-in, deactive all the rest ( remember though to keep activated the maintenance mode plug-in). Run Instant Upgrade, set-it up correctly. If you don’t know, just ask here. The upgrade should be done in a minute or two, maybe less.
There’s not much you could do from this point on, just sit back and relax. You should have a working Wordpress installation in a matter of minutes.
P.S : If you’re upgrading with this method, and your hosting uses cPanel ( most hosts do ), and you’re not sure what to put into the FTP path to WordPress box, try completing it with /www/ or /public_html/ ,that is if your blog is installed in the main directory. If not, it’s /www/yourblog/ or /public_html/yourblog/ - remember to replace yourblog with your folder name, where you installed Wordpress.
