How to migrate SD-WAN image to IOS XE with ISR 4K or 1K?

[DaeHeon Kang]

Hello,

I am trying to find the procedure how to migrate SD-WAN image to IOS XE with ISR 4K or 1K.

Is there any kind of Cisco document about it?

Hi, 

It's well documented here: 

https://sdwan-docs.cisco.com/Product_Documentation/Getting_Started/Hardware_and_Software_Installation/Software_Installation_and_Upgrade_for_IOS_XE_Routers

Regards,

That document is for upgrading IOS XE to SD-WAN image.

I am looking for any stuff about downgrading SD-WAN image to IOS XE.

[elesani]

this is also documented at very end of the same link that I shared. simply, you need to:

- reload the router

- break into ROM MON

- boot router with a none-SD-WAN IOS-XE release.

I missed the information the end of the document.

Thank you, Elesani

I could not be able to open that link. Do you know any other solution to this problem. I am trying to convert SD-WAN os to IOS-XE on cisco routers.

Hi, I have the same issue where I need to do downgrade to IOS XE but the document detailing the process is no longer available

• Sorry, the page at https://sdwan-docs.cisco.com/Product_Documentation/Getting_Started/Hardware_and_Software_Installation/Software_Installation_and_Upgrade_for_IOS_XE_Routers could not be found.

Do you guys perhaps still have it or can upload the actual pdf please?

This might be a little too late, but might help someone else that lands on this page, as I run into the same issue.

How I was able to migrate an ISR 4221 from an SD-WAN image to IOS-XE was to:

1. download the IOS-XE image from the Cisco software site to a USB flash drive. I then connected the USB flash drive to the router

2. copy the IOS-XE image file from the USB flash drive to the router's flash

   e.g. Router#copy usb0:isr4200-universalk9_ias.16.06.05.SPA.bin flash:

3. after the image file has completed copying, reload

4. interrupt the reload so that the router boots into ROMMON

5. in ROMMON, change the boot image file to the IOS-XE file that you previously copied

   e.g. rommon 1 > boot bootflash:isr4200-universalk9_ias.16.06.05.SPA.bin

At this point, the router should then proceed to boot using the IOS-XE file, and you'll have the router migrated from the SD-WAN image.

Post migration if you're facing any issues like Controller mode or Autonomous mode. pls follow the below link

Do this:

1. Reboot

2. Break

3. In Rommon, insert FAT formated USB Flash with IOS-XE bin file.

4. boot usb:/filename.bin

5. Format bootflash:

6. Copy from usb: to bootflash:

7. reboot

Hi,

I had this issue too and tried by doing the .bin file but the router did not recognize this file and i woudlnt take it to boot.

After reading a bit I noticed that routers with IOS SDWAN 16.10.3a version only recognize .PKG and .CONF files, so what  I did was

1. Copy the   IOS XE (in my case it was version 16.9.3) from a USB memory to the bootflash: drive

2. Generate the package from a .BIN file to a different directory

 a.- Router# mkdir bootflash:isr4400-universalk9

 b.-Router# request platform software package expand file bootflash:isr4400-universalk9-NIM.bin to bootflash:isr4400-universalk9

3.-Enter the ROMON mode and force the router to start with the recently created .CONF file 

rommon 1 > boot bootflash:isr4400-universalk9/packages.conf

4.After booting you need to change the register configuration and the boot system conf

Hi,

I have a direct inquiry and i hope to get a clear reply. I'm still in the process of discovering/exploring Cisco Viptela SD-WAN whole solution architecture from a theoretical perspective. I need to determine the compatible ASR1K XE standard based IOSs series routers that are XE SD-WAN capable. Reviewing Cisco official [resources/documents] about XE platforms than can support XE  SD-WAN IOSs, the release notes for [Amsterdam 17.3.x - Amsterdam 17.2.x  - 16.12.x ] list the supported ASR1K routers which are only [ASR 1002-HX and ASR 1002-X & ASR 1001-HX and ASR 1001-X]. In lab environment we have ASR1004 and ASR1006, are those platforms are not SD-WAN capable in context to Cisco XE SD-WAN supported ASR1K resources. Appreciate your feedback !

Copy new IOS to bootflash:
__________________________

Router#copy tftp: bootflash:(image name)

After the ISO image is copied:
______________________________

Router#config-transaction
Router(config)# config-register 0x0
Router(config)# commit
Router#reload
Proceed with reload? [confirm] yes

Switch will reboot in Rommon mode:
______________

rommon > boot bootflash:(image name)

After reboot:
_____________

Router#config-transaction
Router(config)# config-register 0x2102
Router(config)# commit
Router(config)# exit

Router#controller-mode disable
Disabling controller mode will erase the nvram filesystem, remove all configuration files, and reload the box!
Ensure the BOOT variable points to a valid image
Continue? [confirm]
Do you want to abort? (yes/[no]): no

Would you like to enter the initial configuration dialog? [yes/no]: no

Would you like to terminate autoinstall? [yes]: no

After reboot:
_____________

Delete the old unwanted sd-wan IOS:
___________________________________

Router#dir
Router#install remove inactive file bootflash:(image name)

Router#write

Keep Helping.
