Transfer Game Earnings to Place Collaborator

A few days ago, my friend’s account got terminated. There, he uploaded a football game which I was a collaborator for, assisting him with development and whatnot. During the last couple of months, the game has made plenty of earnings in Robux, however, we cannot access them anymore. In this context, I have the following question(s):
Is there a way to acquire the Robux back on my account?
Can an experience be changed to a group or another account?
For context, I am still part of the game, as a collaborator and I am able to edit most of the place’s settings and still develop to an extent.

For transferring game ownership and earnings, you would need access to the current owner account.
If the account is terminated, then there likely isn’t much you can do.
You can try asking Roblox support to change it, but don’t hold out hope.

(This reason is why people tend to use holder accounts for groups and games)
