Transport targets and multiple SLD

HI

We are doing Production Cutover activities. We are transporting directly from DEV to PRD.

We have two SLDs for both Prodction and Development.

Where do I have to create ttransport target ? In DEV SLD or PRD SLD?

In DEV SLD we have all technical systems. For example I have the technical systems of both DEV and PRD ECC systems in DEV SLD. Howevr I don't have the business sytems of both DEV and PRD ECC systems.

Can I create a Buis ystem for ECC production technical system in DEV SLD with the same name of the ECC Business system maintained in PRD SLD and do the transport target in DEV SLD?
