Ten or so years ago, when I was running a business of ~5 people, I signed up for AWS using my personal account. Now that the business is larger, I'd like to transfer the root account to our IT director but it's tied to my personal Amazon account so I can't do that without transferring my whole account to him.
I asked AWS to separate the two accounts (which is a thing they can do!), and the response I received a week later was:
After carefully reviewing your request alongside the Service Team, we are unable to separate your AWS and Amazon.com accounts. Having said this, please note that we continuously evaluate eligibility for this separation process. While we are unable to provide you with a specific timeframe that your account may be eligible, we may automatically complete the separation process for you in the future.
