Nexus 5548UP Upgrade

Hi All,

 

I was hoping to get some feedback about the approach I was going to take for a Nexus upgrade.

 

The current code is 5.2(1)N1(7) and I intend on migrating to 7.3(3)N1(1). There are two switches in a VPC configuration with no FEXs involved and no FC. The switches are pure L2 and serve as the access layer to a UCS blade center.

 

The upgrade will be done under a maintennace window and I intend to take one of the following paths:

 

ISSU

5.2(1)N1(7) > 7.0(8)N1(1) > 7.1(4)N1(1) > 7.3(3)N1(1)

 

Or to save some time due to limited window

 

Part ISSU then Disruptive

5.2(1)N1(7) > 7.0(8)N1(1) then disruptive to 7.3(3)N1(1)

 

The question was whether a disruptive upgrade from 7.0(8)N1(1) to 7.3(3)N1(1) may trigger bug CSCul22703 which can cause config loss with a disruptive upgrade. Looking over the bugid it looks to affect only 5.2(1)N1 and some 6.x code. Could anyone confirm if this bug also affects other code versions?
