The biggest challenge I faced was in migrating my SVN checkout (not discussed in Pete’s post, but people who install via FTP or use the auto upgrader don’t need to worry about this), and Pete noted the only gotcha that I might have encountered: changing the .htaccess to use a different file that had been used in WPMU.

Will similar methods also work with upgrading the regular WP 2.9.x install to the 3.0 beta 2? Just replace all the files and so on? I really need to have the 3.0 install as there’s a bug fix that I’m in an urgent need of.

Are you sure you are activating the theme and not just enabling it for a blog? Themes can be enabled for blog form the Themes screen under Super Admin or from the Blog Options screen. You can activate a theme on the Themes screen under Appearance in the backend for a blog.

Extract the WordPress 3.0 Beta 2 in your public_html folder or

public_html if that is where your old installation was. You'll need to keep your old wp-config.php file and then copy your old themes and plugins folder to wp-content. That should take care of your problems.
