Splitting MU

  • A few of the sites I had installed in MU are exploding way beyond expectations traffic wise causing all of my sites to occasionally get error 500s due to lack of resources. I’ve already got them as optimized as they’re going to get and am running caching and cloud flare. They’re not quite big enough to for me to go to a virtual or dedicated service yet so I’m just moving them to another shared hosting account for now. I want to take 5 of the 14 sites to another entire new MU install.

    What is the preferred method these days for splitting MU? I was thinking I’d just copy the database and WordPress install in whole, switch over the relevant domain names and then delete tables and uploads folders from each of the two databases.

    I’m hesitant to use Export/Import because it presumes live websites on each side with different domain names, making it hard copy /uploads easily and preserve the posts IMG links. And I am not looking forward to fixing the address on 10,000 images. Again.

    I was looking at Duplicator, but it is unclear where /Uploads are stored while being copied.

    I forgot to mention that the sites I want to split out are all subdomains of the same domain so i believe that if I take one down, all will be down. Which will mean all the sites will be offline for the duration which we’d like to minimize.

    Hi hamellr! Your post flew under the radar, since most of us search for “no replies” and you made a second reply. :-/ sorry about that!

    Personally, I use BackupBuddy to do this. Multisite support is in “beta” for BUB– has been for years, probably always will be — but it works.

    You network activate BUB, but inside the subsite dashboard, you can create a backup for that single site, then migrate it with the importbuddy.php script.

    BTW, also works the other way: you can import a single site into the network using BUB.

    It’s a paid plugin, but totally worth the time-savings and headaches for migrating out/in of networks!
