Nexus Upgrade NXOS + EPLD from 6.1(2)I3.5 to 7.0(3)I4(8b)

[F3nrir]

Hi there, this is my first time upgrading Nexus 9k switches and just looking for some peace of mind on my upgrade path.

Upgrading 2 nexus devices that are vpc peers one acting as primary no load balancing. The idea is to start with the primary first and let it failover to the secondary during the upgrade.

HIGH LEVEL

Copy NXOS .bin to bootflash:

Perform #show install all impact nxos bootlfash: Nxos.7.0.3.l4.8b.bin

Perform #install all nxos bootflash:Nxos.7.0.3.l4.8b.bin

Copy ELPD .img to bootflash: from file server

Perform #show install all impact epld bootflash: n9000-epld.7.0.3.l4.8b.img

Perform #install epld bootflash:n9000-epld.7.0.3.l4.8b.img module all

sounds like you have plan in place. ( make sure you take config backup and do it in maintenance window)

here is additional reference document :

Thank you for those tips - I will make sure those are included in my plan.

For anyone wondering, My upgrade went successful using my above plan. VPC peers failed over properly and I was able to maintain connection the whole time.
