[ANAKIN_TN]

Hello 

Im planning to upgrade two cisco 3548 in vpc domain from version 6.0(2)A8(9) to the version 9.3(8) .

whats is the best way to do it without disrupting the service ? 

Can both switches run on different VPC version  for exemple :

Switch 1 on version 6.0(2)A8(9)

Switch 2 on version 9.3(8)

Upgrade of Switch (no HA ore resilience will always service intruptive)

Sw1 and Sw2 both in production ?

if you like to build vPC both should be same hardware and same nexus os

when they are in vPC you can do ISSU upgrade with less service intruption. (only for dual homed devices)

orphan ports always have service outage.

Upgrade from 6.X  to 9.X is step upgrade required

• Then upgraded to 6.0.2.A8.9
• Then upgraded to 9.2.2
• Then upgraded to 9.2.3
• Then to 9.2.4
• And finally to 9.3.6
