We have some 5100 switches running as core and edge within our current fabric which will be end of software support life imminently.
The 5100 core run ISL's into a 7800 which acts a cross site switch within another Data Centre.
We also have some 6510 brocade switch running as an edge switch in the same fabric.
Question is .. Can we easily make the 6510 core by simply replugging the ISL switches from our cross site 7800 swithches into it and re-patching the relevant core required ports (Storage etc ?)
how is both DC connected ? Are you using FCR?
