I have a client with an AWS account already supporting an existing production environment. They've contracted with us to build a new and large ecosystem of software but do not want to give us administrative control of their existing account. The solution we're going with to solve this is an AWS Organization and a new AWS Account for this new software.
My question is, will logging into their existing AWS Account and creating a new Organization be disruptive to existing production systems? I'm sure the answer is no, but I want to be validated beforehand.
Of course if we create SCPs and OUs we can disrupt services but I'm just asking about the act of creating the Organization.
I've done a ton of looking and even asked someone with several AWS certifications that wasn't sure of this so I hope someone here can provide some info on this
Thanks
