Hi Team,
We have pair of Nexus9000 C93360YC-FX2 which are connected to Nimble Storage HF60 with 2 4GB FC connections from each Nexus to Each controller. (When we installed the Nexus, we tried to connect it with 8GB, but as per Cisco Bug, it's working only with 16 or 4 GB, and we had only 4GB).
Now, we purchased 16GB SFPs (ds-sfp-fc16g-sw)to upgrade to connections.
My question is, what is the best way to di it without a downtime ? If I'll replace from 4GB to 16GB one by one, will it work meanwhile, while the Nexus will have some ports to Nimble with 4GB and some with 16, few minutes until I'll complete to replace it all ?
Here is a draw :
thanks in advance !!!!

Sure, replace one by one and check connectivity from initiator side

To upgrade the connections from 4GB to 16GB SFPs on your Nexus 9000 switches connected to Nimble Storage HF60 without incurring downtime, here is a step-by-step plan to ensure a smooth transition:
Preparation:
Redundancy Check:
Upgrade Process:
Verification:
Testing:
By replacing the SFPs one by one, you can maintain at least one active connection from each Nexus switch to each Nimble controller, ensuring continuous operation and minimizing the risk of downtime.
This method ensures that your system remains operational while upgrading to higher-speed connections, leveraging the redundancy built into your storage and network infrastructure.

** Of course there is a mistake on the draw, and the left Nexus is n9k-dc-A
