I rarely do this, but this plugin is such a time saver, that if there is a 100 star rating, I would give it gladly. Looked for couple of days the ways to join single sites to a multisite, this is only solution and it works great. Much better than other similar plugins with same purpose. I will share it to our WP community as well. Thank you

The plugin is simple and smooth. I did have a small issue but after contacting support it was an error on my end and they quickly resolved it and helped me migrate a subsite to a single site. More impressively they helped during a typhoon! Now that is dedication! 100% recommended! 👌

I've found this to work wonderfully with a legacy WP Multisite setup. Not many other plugins can work well with these old sites. Really impressive.

This is about the only free plugin which let you, in a super simple and convenient way, backup a single subsite from a multi-site WP server setup and restore it to a single site server setup. I tested restoring a single site to a multi-site WP setup and it works flawlessly without any serious issue. Hats off to the developer! P.S. the developer seems to like air planes (GR4, C130), just like me, lol.
