how to upgrade isr 4451 fuji ios?

[baselzind]

i have  a isr 4451-x router with fuji 16.9.2 which i need to upgrade to 16.9.3 , i read the upgrade manual which was very confusing and unclear so i was wondering is it just like the old method of doing the below

no boot system

then

boot system bootflash:isr4400-universalk9.16.09.03.SPA.bin

then reload? and the router would come up with the new image?

[balaji.bandi]

you do the tradional way here is the document :

https://www.cisco.com/c/en/us/td/docs/routers/access/4400/software/configuration/guide/isr4400swcfg/bm_isr_4400_sw_config_guide_chapter_0101.html

First i boot with New IOS and test all working as expecte, then delete old one copy the new image to flash and change to boot variable.

make sure you read  the release notes before upgrade.

So the method i mentioned works?

[Mark Malone · Accepted solution]

you need boot system flash bootflash:imagename

Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# boot system flash bootflash:isr4400-universalk9.03.10.00.S.153-3.S-ext.SPA.bin
Router(config)# config-reg 0x2102
Router(config)# exit
Router# show run | include boot
boot-start-marker
boot system flash bootflash:isr4400-universalk9.03.10.00.S.153-3.S-ext.SPA.bin
boot-end-marker
Router# copy run start
Destination filename [startup-config]?
Building configuration...
[OK]
Router# reload

So these steps should be enough to upgrade to 16.9.3 in my case?

[balaji.bandi]

yes it works. do this on maintenance window, it require reboot the device.

Thank you alot , i read something in the upgrade process called consolidated or something do you know what it means?

Managing and Configuring a Consolidated Package Using copy and boot Commands

To upgrade a consolidated package, copy the consolidated package to the bootflash: directory on the router using the copy command. After making this copy of the consolidated package, configure the router to boot using the consolidated package file.

The following example shows the consolidated package file being copied to the bootflash: file system via TFTP. The config register is then set to boot using boot system commands, and the boot system commands instruct the router to boot using the consolidated package stored in the bootflash: file system. The new configuration is then saved using the copy running-config startup-config command, and the system is then reloaded to complete the process.

[Mark Malone]

yes thats from the doc , consolidated upgrade

[Leo Laohoo]

Has anyone read the Release Notes?
Is the router doing any NAT? If the router is doing NAT, make sure you're aware of CSCvo36188.

[baselzind]

can i upgrade directly to Gibraltar-16.10.2?

[Leo Laohoo]

Read the Release Notes and see if a ROMMON needs to be upgraded or not.

[baselzind]

But is there any different steps for upgrading from fuji ver to gibraltar ver?

As suggest worth reading the relase notes always when you upgrade. most of the steps already mentioned required ROMMON Upgrade or not, what is the system requirement.
