Dual-fabric migration

[Madura Malwatte]

I just want confirmation that dual-fabric design to multi-pod / multi-site is currently not supported. Is this correct? 

BRKACI-2125 shows this:

But from this link mentions "The Brownfield to Brownfield use case is only supported in this release if both Cisco APIC sites are deployed with the same configuration. Other Brownfield to Brownfield use cases will be deployed in a future Cisco ACI Multi-Site release."

So if both my APIC sites are not exactly the same configuration then there is no way to migrate to multi-site?

What about migrating to multi-pod?

At the moment the only real option to connect two fabrics together is either via: vPC, OTV or VXLAN via a L2/L3 DCI?

Correct, MSITE is super new. Later this year there will be more options. For MSITE you'll also have to take into consideration the Egress flows with GOLF devices.

For Multi-POD if you are running 3.1 and within 50ms you can stretch your APIC clusters.

MPOD is way more mature then MSITE.
