Seems like something ESRI should have figured out before selling ArcGIS online as a legitimate webmap building application. But we have recently struggled along with ESRI customer service to do something as simple as transfer a webmap application we built on our Enterprise account to the client Enterprise account.
There should be a simple way to doing this so the exact webmap application that a client pays for can be entirely transferred to the client's ArcGIS online account including all the associated layers. We don't want to simply share the webmap created on our account, we literally want a usable copy cloned on the client's account so they can edit a version that is independent of whether we continue to host the application and its layers on our account.
We spent more than a week struggling to see how we can do this using the ArcGIS Online Assistant, Partnered Collaboration, as well as Shared Groups. But no matter what we do, the webmap still references our layers or is transferred in a way that loses all the formatting we set up. Seems like nobody at ESRI Customer Service could help us out with this in an elegant manner that doesn't require the client side to also understand python...
Are we missing something or did ESRI not figure out something very basic for enterprise accounts?
