Retrofit for EHP update project

Hi everybody,

Is it possible to use the Solution Manager 7.1 Retrofit functionality to keep synchronized two landscapes during an SAP ERP EHP update project (Dual Maintenance)?

I have seen a lot of discussions about Retrofit but few about Retrofit during SAP ERP upgrade or SAP ERP EHP update projects. I have only seen some non-answered posts about this subject.

Can somebody help me with that? If someone could point some documentation it would be nice.

Thank you very much.
