MDG-F objects replication from ECC to MDG

Hi Guru's,

here we have a scenario that, have to Replicate MDG-F objects( & Custom data model objects using flex mode)  from ECC to MDG (which is reverse from normal standard process). For example we use the file upload method to upload FI and Controlling objects in MDG staging area. What we now want to achieve is to automate this process. This looks tricky (for example to use MDG APIs) given that we have editions and also hierarchies.

Thank for providing any suggestions or ideas.

Regards
