Hello,
In an effort to upgrade an old 40G network to 100G I may look at replacing a couple of switches, all of them are in different VPC segments.
Our aggregation layer consists of switches N3K-C3164Q which are all in VPC domains, they may be replaced with N9K-C9364C. Can I replace each VPC node one by one? Is the VPC going to converge between C3164Q and C9364C?
The same upgrade may need to be performed with N9K-C9396PX. Can I converge a VPC between 9396PX and 93180YC-EX and replace nodes one by one?
Of course I will keep in mind to observe equal port speeds towards the downstream switches.
Thank you.

Hi @ss1
No, it is not supported to have vPC between different families of Nexus, not even between different models from the same family:
You can find more details about vPC in the config guide (where the above bullets are also present): https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/93x/interfaces/configuration/guide/b-cisco-nexus-9000-nx-os-interfaces-configuration-guide-93x/b-cisco-nexus-9000-nx-os-interfaces-configuration-guide-93x_chapter_01000.html
Stay safe and happy new year!

Thanks for the information Sergiu.
What if we have N3K-C3524P-XL and N3K-C3524P-10GX. Or between different SKU of 9300-FX. Are they considered as different type?
Thank you.

Hello,
Is possible make VPC between N9K-93180YC-FX3 and N9K-93240YC-FX2?

I have a slightly different question: Can I put together a VPC from a Cisco Nexus towards a Cisco Catalyst? If yes, what will then be on the Cisco Catalyst side, port-chanel?
