Hi!
I have a scenario where a customer is currently using two 10GB ports in a port channel between two 56128P Nexus switches as the vPC Peer Link, and wants to upgrade this to an 80GB port channel by leveraging two unused 40GB ports. vPC is operating normally and there are no orphan ports, and since the ports themselves have different physical capabilities I obviously cannot simply add the 40GB ports to the existing port channel while the 10GB ports are members.
My question is essentially this: can two port-channels exist at the same time with the vpc peer-link command entered on both?
I have performed this type of upgrade before and typically do something like the following:
This works fine, and in a well-designed scenario causes no downtime. However, in a scenario with many orphan ports, for example, I think it would be easier and quicker if I could just:
I have not had the opportunity to test this, hence my question. A secondary question would be: have you done this type of upgrade, and if so how does your process differ from mine?
Any feedback is appreciated.
Thanks!

I just did this exact upgrade on Nexus 7700s.
It did not allow me to have two interfaces configured as vpc peer-links.
I did it exactly as you did:
