Can I export and then import the same applications developed in the Neptune DXP - SAP Edition to the Open Edition?

There are too many differences between Neptune DXP - SAP Edition and Neptune DXP - Open Edition apps (like application class and AJAX_ID) so there is no official migration possible. Also, Neptune DXP - SAP Edition uses SAP UI5 objects and Neptune DXP - Open Edition uses Open UI5, so it’s possible to encounter these discrepancies.To do a Neptune DXP - SAP Edition app components in the Open Edition, the recommended way is to re-do the app from the start in Neptune DXP - Open Edition. It is possible however to remote call, and run the Neptune DXP - SAP Edition application within the Neptune DXP - Open Edition context.
