Upgrade firmware on Nexus 5548 with VPC

[mramirez-t]

We have two Nexus 5548s running version 7.1(4)N1(1).  They are configured with VPC.  We want to upgrade firmware from current version to 7.3(3)N1(1).  Since it's running VPC, is there anything special I need to do regarding the firmware upgrade, such as order of switches or anything else I'm not thinking of?  Below is 'show vpc' from switch 1.

Any help's appreciated.  Thanks.

Make sure you run the "show install all impact" command to identify the upgrade impact.

Also, in most case, you want to upgrade using the "install all" command.

For more info and examples have a look at this link

Adding to other post please do read the release nodes.

Is this simple vPC with 2 switches or part of Flexpod, or any FEX connected.

Bare in mind while upgrading single homed device have service interuption.
