ACI Lifecycle Gen1 to Gen3

Hello as we are some early adopters in ACI we have a stretched fabric with Gen1 HW.

Sales has offered a Lifecycle ngor Gen2 hw. BUT gen3 is since, i think February, open for pruchase. So why Gen2 when i can buy Gen3?

But it seems it is not possible to replace Gen1 HW with Ge3 as they are not compatible with each other.

So my opinion is - build a new fabric parallel to the old one and then hard cut over the servers to the mew fabric. As we adv. The subnets with bhp to the DC Core, we could just re-patch the server and then set the metric to a better value for the migrated subnets.

Or would thete be a way to connect both fabrics with each other like leaving the gateway on the old fabric, move the ESX host, and later move the Gateway?
