SAP license key used during DMO of SUM

Hi expert,

When I execute databese migration from ERP on other DB to ERP on HANA with DMO of SUM ,

I have to prepare SAP license key for system migrated to SAP HANA , right ?

In case of ERP's SAP license key , I think that I need SAP license key every type of DB.

So I need SAP license key of ERP on HANA , right?

When I try to obtain a new license key before execute DMO of SUM,

should I provide a installation number/HW key/system ID of source ERP ?

Thanks in advance .
