Hi,
This being my first post - bear with me...
I need to do an ISSU upgrade of two Nexus 56128P switches to 7.3(0)N1(1) for the GEM to support 16Gbps FC transceivers. I just need to have input on the upgrade path as I want to avoid possible issues.
Current version: 7.1(4)N1(1)
Target version: 7.3(0)N1(1)
According to the release notes for 7.3 I need 7.2(1) for the ISSU to be non-disruptive, so far so good. My question is that in the release notes for 7.2(1) it lists 7.1(1)N1(1)-7.1(3)N1(2) as current releases, not my 7.1(4). Is that just due to my release (4) being created after the release notes itself or am I missing something? Can I see somewhere that 7.2(1) is a viable ISSU from 7.1(4) on my way to 7.3?
Feel free to ask qestions if I am unclear :)
Kind regards,
Jonas

I just figured that we cannot utilize the ISSU process as we're running L3 functionality. Do you have any input on how upgrading - distruptive - will affect traffic if I'm running two of them in a vPC pair? The configuration should allow for one to go off-grid, but then, I might miss something :)

Hi,
Upgrade can be done directly:
Current Cisco NX-OS Release | Upgrade to NX-OS Release 7.3(1)N1(1) | Downgrade from NX-OS Release 7.3(1)N1(1) |
7.3(0)N1(1) | Nondisruptive upgrade (ISSU) | Disruptive downgrade2 |
NOTE:
1.Possibility of disruptive upgrade if FC or FCoE is enabled and upgrade is from Cisco NX-OS release 7.2(1)N1(1) or earlier. See CSCuq94445 for more details.
Make sure you always read the upgrade guides and release notes of the target release before performing any upgrades:
