[c-nsp] Migrating a LACP bond on Catalyst to a vPC on Nexus

[Giles Coochey]

Hi All,

Working for a client, they have a need to migrate a LACP bond from a 
Catalyst 3850 stack to a vPC bond on a Nexus pair (93180 TOR type)

There is an existing trunk bond between the Catalyst 3850s and the Nexus 
so the Layer-2 is present across these and VLANs in the bond are the 
same on both switches. The endpoints on the bonds are hosts, and 
configured for LACP (channel-group x mode active), 2 ports per channel.

What advice is there to migrate hosts on the 3850 stack to the Nexus, 
can it be performed in a hitless manner?

Many Thanks!

Giles
