Pretty easy actually, noting that I’ve upgraded from WPMU 2.9 with just 2 sites and running Apache with XAMPP. For the windows IIS users, hmmm… I’ll have to figure it out later at work. But with mod_rewrite enable in httpd.conf and .htaccess already reconfigured on upgrade, that was easy.. The only hiccup was the thumbnails in the secondary blogs were not showing up although the path and files were correct. WordPress does give a note that
“The wp-content/blogs.php file is deprecated. Please remove it and update your server rewrite rules to use wp-includes/ms-files.php instead.”
What it actually means is that you have to edit .htaccess under the root folder and change
“RewriteRule ^(.*/)?files/(.*) wp-content/blogs.php?file=$2″
For
“RewriteRule ^(.*/)?files/(.*) wp-includes/ms-files.php?file=$2″
Quite evident really but sometime you just have to know these things…
