Changing an existing standard wordpress into a multisite

Can an existing standard WordPress be updated to a mutisite without losing all the design work on theme and the plugin setup. We have a membership setup and we do not want to lose the setup. Thanks

    Hi there and welcome to the WPMUdev Support Forums!

    Absolutely! That is the beauty of WordPress! Themes, Plugins and Database orchestrated by a small core of PHP. All Multisite installations begin their life as a single site installation. You can follow:

    You will start by backing up your current site, then opening the wp-config and adding:

    define('WP_ALLOW_MULTISITE', true);

    Once that's saved, refresh your browser and you'll have an option to create a network under the Tools menu. You can follow along from there.

    Essentially, your existing site will be Blog1 in Multisite. You will also create a super-structure called Network admin which is where you will control multisite as super admin. Here you can create new sites, add themes or plugins, and basically tell the site admins what they can and can't do.

    If as you are going thru, please feel free to ask more questions. We've all done this and love Multisite. We also created a manual as a companion to the Codex. You can find it at:

    Hope this helps!
