I just started with a company and we are in process of getting started with AWS. The previous administrator was learning AWS and getting the ball rolling and uploaded a ton of things, but uploaded everythnig to an account that uses his name. I have administrative access to both the old AWS account and a new company one we created. How can I take all the data from S3 buckets and move them over without having to download everything to my pc (it is a few TB of data) and then reuploading it? I tried to go in to the old AWS buckets permissions and tried to see if I could add the new AWS accounts number to it, but it said "Invalid ID".
