I have an old aws account with one hosted external domain. I have a new aws account, and I should manage the domain as a user of the new domain via cli/Terrafrom. How to setup suitable cross-account permissions?
There are a lot of documentation (e.g. http://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_cross-account-with-roles.html ), I've tried a lot of ways, but no luck so far.
