Restauración fallida: "Algunas cargas no se pudieron migrar al nuevo esquema"

Soooo. I’m still stuck on this one. I managed to get my old server up and running again by messing around with putting it behind an nginx server and getting the cert that way (has a different site running on the same domain).

But I would still like to migrate. I’m also afraid I wouldn’t be able to do a restore on the server, should something go wrong.

If there are any other data points I can provide, please let me know!
