Hi @Mani G 

Usually, when I perform similar migrations, there are several things I check:

- the current STP root and what implications are when I add the new switch

- I save the MAC and ARP tables for multiple checks (number of entries, how endpoints are learned and on which ports)

- interface status before and after migration (which are up before and after)

- port-channel status (if LACP is configured) before and after migration

- if routing is configured - routing table and routing adjacencies before and after migration

Basically, I am taking a snapshot of the current state of the switch and network before migration, and compare it with after migration.

Hope it helps,

Sergiu

Thanks! Can i pair vPC between Nexus5K and Nexus9K while migration.

If you mean have a vPC domain with one peer as N5K and another with N9K, then no. You cannot do that.
