I created a world to play with my friends and I wanted to transfer it to a realm to play it all together with greater freedom, but it does not allow me to replace the world, it is urgent for me to have a solution because I am not interested in playing in realm another world that is not the one I did.

Can you help me please? I will appreciate it very much.

I recorded the screen of what happened.
