Moving objects between systems after S4 Upgrade

Hi All,

In a multi-system scenario, 2 copies of S/4 development system are up and running. From which one is 1610 and another is recently upgraded to 1709 from 1610. Thought 1709 is the copy of the 1610, now that one is outdated as development work is going only on 1610.

Can anybody please suggest the way to replicate development changes from 1610 to 1709, without having to rework on the objects.

Thanks in advance.

P.S. SOLMAN is not available.
