EDIT: SINCE WORDPRESS IS NOW WELL BEYOND VERSION 2.3, THIS POST IS NO LONGER RELEVANT AND I HAVE CLOSED COMMENTS ON IT. YOU SHOULD BE UPDATING TO THE NEWEST VERSION USING THE BUILT-IN UPDATER IN YOUR DASHBOARD. This is a step by step guide to upgrading to WordPress 2.3. This guide only takes into consideration plugins installed by Ninja Blog Setup. If you have others then you may need to upgrade or disable them if you encounter any errors. The only plugin that causes any problems when upgrading is the Add Meta Tags plugin. The plugin has been updated now, so you can just grab the latest version and install it. As of writing this post there wasn’t a update to the plugin, but it is a very useful plugin so I have provided a file that has a patch which makes it compatible with WordPress 2.3.

You will be able to import your tags, so they won’t be lost. Backup your entire system by going to Manage / Backup and select all the tables and perform a backup. Run Instant Upgrade to upgrade WordPress to the latest version by going to Manage / Instant Upgrade. If the upgrade needs completion manually just follow the links. Use this plugin (Simple Tagging Import) to import your “Simple Tagging” tags into the new WordPress tagging system. Download and install the plugin and then follow the instructions on the documentation. Go back to your WordPress backup page to include all the tables on your weekly or daily backups. This is necessary since there are new tables from the old version and you want them all to be backed up. Add code to your template to display the new WordPress tags. Do this by going to Presentation / Theme Editor. Open the Single Post file from the right hand menu. And then add the following line: Tags <?php the_tags(' ', ' ', ' ');...
