# MultiSite and legacy code

 * One website I run has a few “sister” web sites. Currently each are running WordPress
   as stand-alone (not multisite-enabled). Each site runs the Dokuwiki system to
   give me a wiki for each site. Am I correct in assuming that because of the wiki
   I am not able to convert the sites into using multisite options of WordPress?
   More broadly, if a site has any kind of “extra” content from some other system(
   a wiki, a redirect service like Yourls, or even just legacy html pages) you can’t
   use the multisite capabilities of WordPress.
 * More details: the sites are all with subdomains site1.example.com site2.example.
   com site3.example.com. So I have three WP installations, three databases, etc…
   I was thinking as I add more sister sites, it will be a pain to have to manage
   each WP installation, so multi-site would be helpful. But because I’ve merged
   the sites with another software system, I can’t use multisite. Thanks for your
   thoughts.

 * That’s a solid _maybe it will be a problem_.
 * Most plugins will work when you activate them on a per site basis, but set up
   a dummy multisite environment, activate the plugin there, and import the single
   site into it via [WXR](http://codex.wordpress.org/Importing_Content#WordPress).
 * If it works on a test setup, it will probably work on a live one too.

 * See above. 😉
 * Multisite is pretty flexible and mostly behaves just like a regular single site
   setup. But for something exotic such integration with an external system then
   your own testing really is called for.
