Issue Opening StoryMap After Copying from AGOL to Enterprise Portal (v11.5) Using ArcGIS Assistant Beta

[John_Herrera]

Using ArcGIS Assistant Beta v20250603.1, I copied a StoryMap from ArcGIS Online over to our ArcGIS Enterprise Portal (v11.5). The copy reported as successful, and all associated items appear to have transferred correctly.

However, when I try to open the StoryMap in Portal, it fails to load. After doing some digging, it looks like there may be known limitations or challenges when copying StoryMaps between AGOL and Enterprise—especially with newer StoryMaps built on the ArcGIS StoryMaps platform rather than Classic.

Any guidance or experiences would be greatly appreciated!

@John_Herrera -- As noted in the ArcGIS Assistant doc, this workflow is not likely to be successful.

The version of ArcGIS StoryMaps on ArcGIS Online is always newer than one running on an Enterprise portal, and StoryMaps are not backward compatible in this way. You could try removing elements from the story data that aren't supported in 11.5 to see if you could get it to work, but I'm not confident in the chances of success.
