How to transfer a project or droplet (not a snapshot) to another account or team?

Hi, I have a droplet with an application that has already been through all homolog process, wich means that I cannot change the IP of the application or else the client will need to restart the homolog process with the government - what is not compatible. I’ve seen some people tried to transfer a droplet by transfering a snapshot. This doesn’t work for us because the IP address should be kept

I already successfully transferred the droplet to a new project and now I’m trying to transfer the project to the new team, with the new billing credit card, so they will be charged for the server after the upgrade, instead of me, but can’t find how to.

The main objective is to transfer the financial responsibility for the server, but the perfect solution is to totally transfer the resource to other account, user, team, etc
