Can´t downgrade c9800-CL in AWS

[kdanielsson]

Hi!

I have install an c9800-CL in AWS the only release to install was 17.6.1 so I do so.

But I need to downgrade it to 17.3.4 because we have 2702 APs.

I run the 17.3.4 bin file and everything looks right under the installations the WLC reboot but came up with 17.6.1 again ????

I have try both GUI and Cli with same result, Is there anyone who can tell me why ???

 - Could you check the boot statements in the startup-config , and or the running config too (compare) ?

How did you downgrade, what is the process did you follow?

[kdanielsson]

Same process as you do an upgrade but with 17.3.4 software

[kdanielsson]

Both boot statement is bootflash:packages.conf when the WLC is in install mode

Can we see the output to the following commands: 

• more bootflash:packages.conf
• dir bootflash:*.conf

Contents of the packages.conf file looks good.

Can we see the output to the command "sh boot"?

[kdanielsson]

usawswlc1001#sh boot
BOOT variable = bootflash:packages.conf,12;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x2102

Standby not ready to show bootvar

All look good: 

• Boot variable points to packages.conf
• Contents of packages.conf point to 17.3.4

The only thing left to do is reboot.

[Arshad Safrulla]

I would say boot from the 17.03.04 bin file (bundle mode) for once and then convert it to the install mode.

1. Upload the bin file for 17.03.04

2. Delete the existing boot statement

3. Add the new boot statement to load with bin file.

4. Reload the WLC.

5. Convert from bundle mode to install mode
