Transferring H5P content between 2 WordPress

Forums: 

Hello,

I have a problem: we are creating a website with H5P content, and we want to have both version: a testing and a production. Both are already set up. Currently, in the testing version, we have 500 H5P tasks, and we must to transfer them to the production version.

Is there any way to do this without manual copying one by one? I'm looking for best method (preferably excluding, for example, system copying, because in the future, it will be problematic). 

 

Thanks in advance!
