For large Enterprise installations this can be the way to go by using a combination of dedicated TCP/IP stacks and host uplinks. Steering traffic is also the only option for some enterprises that have to route that traffic across a separate fibre link to their remote site. Let your own requirements dictate how you design your replication network, not the requirements set fourth in someone else's blog article.
Thanks @daphnissov for writing the migration book. Excellent resource.
May I ask one question on it, I just do know if this is the right place for it.
We are migrating using Inter-C-02. Since this is storage vMotion but using FC traffic will it use VMNIC (phy nics) or FC SAN Switches?
That's a good question to ask. It should still use the vmkernel interfaces for vMotion first executing a svMotion and then a vMotion to move the memory contents.
