NWDI 7.2 merge with NWDI 7.31

Hi,

Currently, we have 7.2 development landscape that includes CE 7.2

connected to NWDI 7.2.

At the same time we have another system with new NWDI 7.31 configured and

we would like to understand how can we "merge" the current 7.2 system into 7.31 system

so we will have one NWDI in the organization.

Is it possible ? how exactly ? can we "Upgrade" 7.2 SCs to 7.31 during the merge ?

Kind regards,

Dimitry
