New update to minecraft realms

I joined a friend's realm and spent a huge amount of time creating, mining, etc and now he tells me the world will be gone as he is updating to the new realm. I was shocked. I asked how I would keep my stuff and he said there is no way. He says it starts over from scratch and this is how he likes it. He is correct? He said he would have to hire someone to move my stuff and he will not do that. Really? Since I am just a player in his realm, I have no choice? Can I somehow take my stuff and move to someone else's realm or another version? He is on xbox and I am on PC if that matters. He says it is not java but is 1.16 version. :(

Solution 1:

It's possible that the owner of a realm can save a world copy of the realm (I know this because when I used to run a realm, I would make weekly world copies of the realm's progress), but I don't believe there's a way for them to transfer the world copy to you for ownership.
