Move organisation management account to another organisation

Question

We have a longstanding account for our production environment that is a management account within an organisation. I would like to transfer this to another org, that has been setup to support all our environments.

I'm getting an "MasterCannotLeaveOrganizationException" exception when trying to leave the first org, what can I do to transfer the account to the preferred org?

Thanks in advance.

Hello.

This exception error occurs when you try to move an AWS Organizations management account to another AWS Organizations.  
As described in the following document, to move the AWS Organizations administrative account to another AWS Organization, you must first disband the AWS Organization.  
Therefore, after moving all member accounts in the existing AWS Organizations to the new AWS Organizations, try disabling AWS Organizations and then moving the AWS account that was originally used as the management account.  
https://docs.aws.amazon.com/organizations/latest/APIReference/API_LeaveOrganization.html#:~:text=MasterCannotLeaveOrganizationException  
> You can't remove a management account from an organization. If you want the management account to become a member account in another organization, you must first delete the current organization of the management account.

You can delete AWS Organizations by following the steps in the following document.
