My organization is currently brainstorming with another organization on how continue providing access to about a half of dozen web applications and data through ArcGIS Online.

Currently, the organization we are in talks with wants to be able to hand off the content/web applications on ArcGIS Online to us to host on our ArcGIS online organizational account.

I haven't found anything that steers us in the right direction on GIS SE and on ArcGIS Online FAQ here appears that this feature isn't entirely possible.

How would we go about doing this? If at all possible?
