Unfortunately, I don't work for Adobe, we are partners. We can get it done using our own solution ( https://www.oneteg.com). Let's talk tomorrow. Here is my email: bdogan at cyangate.com. I will try to help as much as I can.
We can help you transfer them using our OneTeg iPaaS . You need to make sure you have AEM Assets and not Essentials. Essentials don't have an API we can work with at this time. We can also push them to OneDrive if Essentials is in use. Thanks,Bulent
