I just used 10up’s MU Migration plugin to pull the Daily Create (daily.ds106.us) out of the ds106.us multisite, and it was really impressive. You can install MU Migration as a plugin, but also as a package that uses the WP-CLI to make migrations, and it is pretty amazing. It will pull individual subsites out of a WordPress Multisite instance, that can then be imported into a stand-alone WordPress. Or, going the other way, you can use it to import a stand-alone WordPress instance into a Multisite. It is impressive, especially after the touch and go nature of import/export plugins like All-in-One Migration and Updraft that tend to leave a lot of holes that needed to be plugged.
So, a command like the following (daily.ds106.us had the site id of 10) will pull that sites users, active plugins, active theme, and all database details into a zip file call dailcreate.zip:
wp mu-migration export all dailycreate.zip --blog_id=10 --plugins --themes --uploads
From there you would copy the zip file into the directory were your new install lives, and then make sure MU Migration is working on the site. After that you run the following command to migrate the entire blog (including media, users, themes, plugins, etc.):
wp mu-migration import all dailycreate.zip
The only snag I ran up against was the Daily Blank theme was active on the Daily Create site, but it depends on the parent theme WordPress Bootstrap. Seems like MU-Migration has no way to detect this, so I needed to install Bootstrap as well. Once I did so the entire migration of over 1 GB of media was done in seconds. While this definitely falls under the niche WordPress topic post, if you spend your time like we do at Reclaim Hosting migrating WordPress sites, then this is a definite must for the plugin toolbox.
