Hi Folks, we are moving a UCS FI-6332 system from old Network switches to new ACI Leaf switches. As part of the physical move, we are also changing the uplink ports on the FIs: Previous ports being 10G/SFP port and new ones are 40G/QSFP.
Now I know there is a whole bunch of internal vif pinning inside the UCS all the way from the ethernet uplinks to the blade server vnics (ESXi in our case). Does the ESXi hosts need to be rebooted or re-discovered if the uplink network ports have changed so that the traffic now flows via the new ports?

Unless you created specific pinning policies (not normally the case), then the service profile defined vnics are going to autopin to what ever available uplink allows all the vlans the vnic is configured for. This happens automatically, no need for rediscovery, etc.
Your vnics will go into down state if you have no available uplinks to pin to while you are shifting over you connections to the new uplink ports and upstream switches.
