Yes, you can move or clone to a separate server with a single click. Only volumes are not currently supported when doing this.

How? I can't find it in the docs.

Just use the Clone button on the Resources page or on the Resource Operations tab of an application - the functions are very self-explanatory, so there is no documentation yet.

Me neither. I found this https://github.com/Geczy/coolify-migration but if there's a native way to do it that would be great.

Full instance migration is in development but not yet released.

I understand you think it is obvious and no docs are required, but it is a bit ambiguous ”you can move or clone to a separate server with a single click” and ”Full instance migration is in development but not yet released.”
