C4500 Sup Redundancy OS upgrade.

[inb]

Good morning.

I am trying to upgrade the C4500 engine redundant equipment to the OS.

Current version: 3.4.0SG
Current ROMMON: 15.0(1r)SG5
New version: 3.11.3aE
New ROMMON: 15.0(1r)SG10

// config
redundancy
mode sso

It is operating in SSO mode.

However, in order to go from 3.4.0 to 3.11.3, we need to upgrade ROMMON to 15.0(1r)SG10 first.
I have completed the procedure below using the guided documentation and the method seen by the community.
Please help me to make sure the procedure is correct.

-Active SUP(Slot 5)
1.no boot system flash bootflash:cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin
2.boot system flash bootflash:cat4500-e-ios-promupgrade-150-1r-SG10
3.boot system flash bootflash:cat4500e-universalk9.SPA.03.11.03a.E.152-7.E3a.bin
4.config-register 0x2102
5. write
6. show bootvar
7. redundancy force-switchover
7-1. Active SUP Upgrade....
7-2. Active SUP Upgrade Complete.
7-3. show redundancy (Booting and SSO check)

-Standby SUP(Slot 6)
8. no boot system flash slavebootflash:cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin
9.boot system flash slavebootflash:cat4500-e-ios-promupgrade-150-1r-SG10
10.boot system flash slavebootflash:cat4500e-universalk9.SPA.03.11.03a.E.152-7.E3a.bin
11.config-register 0x2102
12. write
13. show bootvar
14. redundancy force-switchover
14-1. Standby SUP Upgrade.
14-2. Standby SUP Upgrade Complete.
14-3. show redundancy (Booting and SSO check)

15. End.
16. As a result, Slot 5 operates as Act, Slot 6 Std.

There is a lot of downtime.
Is the procedure above correct?

1. no boot system flash bootflash:cat4500e-universalk9.SPA.03.04.00.SG.151-2.SG.bin

6. boot system flash slavebootflash:cat4500e-universalk9.SPA.03.11.03a.E.152-7.E3a.bin

This is NOT necessary if the redundant supervisor card is in the same chassis as the primary supervisor card.

14. redundancy force-switchover

If that was me, I would just issue the "reload" command.

boot system flash bootflash:cat4500-e-ios-promupgrade-150-1r-SG10

After the chassis has rebooted, I would remove this line.

Finally, why choose 15.0(1r)SG10?  This file was released back on 03 July 2014.  

I would recommend going straight to 15.0(1r)SG16 instead.

Thank you.

If so, will procedures 8~13 disappear?
Simply through redundancy force-switchover
Is the process complete by simply switching the engine?

[inb]

The sup model is 7-e.
So I can't use that version.
I am going to proceed with the minimum ROMMON version in the guide.
As you said, in step 14 I will reboot the entire chassis via reload.

[inb]

After reloading at number 14
Is the active engine slot 5?
Or is slot 6 active before reloading?

[inb]

What's your opinion on tesk 2?
I think tesk 2 is cleaner.
But there is no way to verify it.

Thank you.
