Replacing spine by a different spine model

[ANAKIN_TN]

HELLO, 

i have cisco aci fabric with many pords, one of my pods are made by 2 x Cisco Nexus 9332C spines connecting 16 leaves with 4 uplinks for each leafs.

I already used all the ports of the spines and i want to replace the 32 ports Cisco Nexus 9332C  spines by Cisco Nexus 9364C 64ports  spines that i already buy  .

How can i proceed withiut impacting the production and the traffic in the fabric ? 

thers is any restriction about upgrading the spine hardware ? knowing the if i will replace using the RMA method or like im replacing a broken spine the pod will works for a while with 2 spine having different harwares .

Thank you in advance for your help .

Regards

Hello Guys, 

I have new update about this, the cisco TAC says that there is no problem replacing this by an another spine we just must keep te same port mapping.

Hi M02@rt37

A side question, can the C9500 serve as spine for Nexus 9300 leaf?

Any back draw on that?

Thanks

Hello @ANAKIN_TN 

In term of design, Catalyst switches are typically used for campus and enterprise deployments, while Nexus Switches are more common in Data Cnnter environments.

Hello @ANAKIN_TN ,

have you replaced the spine in your environment? 

If Yes, then please assist me by providing pre-requisite and instruction about replacement.

Have you faced any problem like traffic loss while replacing the spine? What time required for new spine to join the fabric after configuring node ID and hostname?

After one spine goes down then all workload shift to the other spine which is in production. So what is the behavior of that active spine? Its memory and CPU utilization.

Please assist
