Hello, looking at the brownfield to greenfield migration document from Cisco there's a L2 and L3 DCIs. At this point we are just migrating L2 to the the new DC and L3 will remain at the brownfield. Is the L3 DCI required for this step? Or is it just required until we actually migrate L3 and we need to route out of the brownfield DC?

The Greenfield fabric is already up and we've built it through DCNM. Next step is really the DCI's and start migrating some VMs.
Thanks
