cCTS with managed system transport domain controller

[PrasantaM]

In current landscape, ChaRM configured with domain link to all the managed system's DC, where every Dev system is the domain controller. TMS RFCs are created DEV(DC) -> QAS ->PRD, cycles are created without cCTS activation. Dev system already have over 2k normal change document, some of them are already tested successful.

Now have below queries:

1. cCTS migration possibilities, where internal RFCs between DEV(DC) ->QAS -> PRD on managed system blocked by firewall and DIR_TRANS is common for all the servers including Solman.

2. Function redefine Landscape on existing phase cycle, after creating cluster and activating cCTS, any effect current ChaRM operation.

Thanks in advance.
