Moving new world to PTB

I recently started a new world on a dedicated server that I’m running (not 3rd party).

Didn’t realize there was a big update in the PTB. Does anybody know if I’d be able to move my world onto the PTB without issue? I imagine we’d stay on this until the update is fully released, so I’m thinking there shouldn’t be an issue.

Any pointers on how to do that also would be helpful but I’m sure I can figure that out :)
