Just run a trunk between the two with all the VLANs you need while you are
migrating.
It will not be hitless when moving the port-channels, as the LACP ID's will not
match between the 3850 and the VPC member switches.
Be conscious of your gateways, and check spanning tree is forwarding on
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
