Hi All,
I'm in the middle of replacing the vSwitches and DVS's in our ESX environment to purely Cisco Nexus 1000v's. Our environment is a mixture of vSwitches and DVS's.
Is there any prerequisites I need to be aware of before to perform this migration?
Also any real life tips and hints would be great on this, as I have been reading thru all the installation guides from Cisco/VMware, but they seem to only outline brand new installations from what I can gather
We dont want to break the system in the middle of upgrading! 
Look forward to hearing from everyone,
Cheers
R
