Hello!
I have 3 pairs of 6807 VSS switches. Each stack is single supervisor VS-SUP2T-10G.
Current version is
(s2t54-ADVIPSERVICESK9-M), Version 15.1(2)SY6
ROM: System Bootstrap, Version 12.2(50r)SYS2
Recommended version is
s2t54-advipservicesk9-mz.SPA.155-1.SY6.bin
It seems like I cannot do ISSU with this upgrade. Is there another way I can do this without a full disruption to our Core network?
If I have to take it out all at once how long will the upgrade take?
Thanks,
Waqas
Solved! Go to Solution.

I never use FSU/eFSU or ISSU because it not a one-size-fits-all solution. To some it may work but I have had some bad experience that I just result to going to the old method which has worked 10 out 10.

If you want to do FSU/eFSU or ISSU make sure the TAC engineer is on the phone when you are doing it. It will also help if the Cisco AM/SE is involved in the FSU/eFSU or ISSU "cc-ed" into the email trail.

Personally, there are many other ways you can choose for the upgrade, since VSS bit odd results i see especially 2 different versions of IOS when you upgrade per chassis
12.2X to 15.X.
here is good discussion,

Hi, we are on version Version 15.1(2)SY6 currently, considering version Version 15.5(1)SY6
Also that discussion is for a dual SUP chassis, which I don't have.

apologies corrected my statement - look at the approach and discussion had in the thread and consider our experience on the filed results.
i know downtime biggest factor nowadays, but think planned downtime vs disaster.

You are going to 15.5(1)SY version. This means a mandatory FPGA upgrade. Read my response in the link @balaji.bandi have posted.
And remember, when the proverbial "thing" hits the equally-proverbial fan, it will be a long, sad and lonely drive to the site. And, most importantly, no one will hear you(r) scream.

Is there a version I can go to that won't require the FPGA upgrade?

Read the Release Notes very, very carefully -- I cannot stress this enough.
15.4(1)SY (and earlier) version do not require FPGA.

That should work, the only thing I'm not sure on is
CSCva82153 cat6000-firmware Multicast traffic black-holed with Nappar LC mixed mode
We are using some multicast for CCTV but I don't know what that means. Could we do FSU to 15.4(1)SY safely?
My only reason to upgrade is the current version is end of support in June. We will likely do a refresh to SDA in 2 years so anything that would be supported until then would work. Don't need to go to the latest version.
Thanks,
Waqas

Deprecation of Type 4 passwords.

Secure FPGA is a feature to protect Gold region of FPGA Serial Peripheral Interface (SPI) flash. FPGA prevents any modifications to Gold region of FPGA flash. Cisco IOS achieves this by bundling the latest secure FPGA image and auto-upgrading the Gold and Upgrade regions of FPGA flash to this image. Release 15.5(1)SY4 introduces a change to Cisco IOS FPGA auto-upgrade procedure.
Before proceeding with the upgrade to Cisco IOS Release 15.5(1)SY4, see Secure Field Programmable Gate Array and Performing FPGA Upgrade for complete information about the change in FPGA auto-upgrade procedure and how to perform FPGA upgrade.
