Hi
I have a Net App San connected to our Nexus 5k Switches. The current setup is as below.

This San will be replaced with new SAN. I have to keep both San data-stores presented to ESX hosts until migration completed. Which design option work or not? .
Option1:Adding the new SAN interfaces to the existing setup as below.
Option 2:
Creating new Vlans For NFS and Fcoe
Creating new VSAN and Fcdomain
Adding VLANs to Carry FCoE Traffic Vlan
Creating New Port-Channel and vPC
Creating new Fcalias and adding new Netapp interfaces pwwn (do I have to add the existing SAN Pwwn? To this new Fcalias )
Creating new Zone and add members to the new Zone
Creating a new Zone Set and activate new Zone set (Only one zone set can be activate at one time ?) or add new Zone set to the activate Zone set.

Thanks in advanced.
