Hi @atalebzadeh 

1. Yes, you can convert the uplinks to downlinks.

For reference, you can check the cfg guide. Also, I would recommend you to check out the limitations.

"""

Uplink and downlink conversion is supported on Cisco Nexus 9000 series switches with names that end in EX or FX, and later (for example, N9K-C9348GC-FXP or N9K-C93240YC-FX2). A FEX connected to converted downlinks is also supported.

2. No, you can have a mix of hardware model. There are however restrictions when it comes to vPC:

• Generation 1 switches are compatible only with other Generation 1 Switches. These switch models can be identified by the lack of “EX”, or “FX” at the end of the switch name. For example N9K-9312TX.

  Generation 2 and later switches can be mixed together in a vPC domain. These switch models can be identified with “EX”, “FX” or “FX2” at the end of the switch name. For example N9K-93108TC-EX, or N9K-9348GC-FXP.

• Example:

  Compatible vPC Switch Pairs:

  • N9K-9312TX & N9K-9312TX

  • N9K-93108TC-EX & N9K-9348GC-FXP

  • Nexus 93180TC-FX & Nexus 93180YC-FX

  • Nexus 93180YC-FX & Nexus 93180YC-FX

  Incompatible vPC Switch Pairs:

  • N9K-9312TX & N9K-93108TC-EX

  • N9K-9312TX & Nexus 93180YC-FX
