as per the information you can directly upgrade . look at the upgrade path  and also read the release noted and compatibility matrix :

Upgrade Path to Cisco IOS XE Cupertino 17.9.x

Community, not delivery and Images, you need to have a support contract and CCO id you download. or contact a Local partner to help you to get a new image.

Thanks for your help, I downloaded the file,

Only I have a problem updating the APSP software on the WLC, because the 17.9.1 firmware is a Bundle mode. “Booted in bundle mode. SMU install is not supported in Bundle mode. Boot the device into Install Mode”

[balaji.bandi]

Then try exting version to install mode and then upgrade.

[yastop]

Do you have an instruction for me?

[yastop]

where can I download the version 17.9.1 Install mode firmware?

[balaji.bandi · Accepted solution]

there is no special IOS required to convert the bundle to install.

in general IOS XE, if you boot with .bin called a bundle, if you boot with packages.conf (its bundle)

follow the below document to convert the bundle to install mode

https://www.cisco.com/c/en/us/td/docs/wireless/controller/9800/17-2/config-guide/b_wl_17_2_cg/b_wl_17_2_cg_chapter_010010111.html

Note: if this is production, take config backup out of the box, and convert in a maintenance window. since required to reboot device.

I recommend upgrading to 17.6.4 instead.

where can I download the version 17.9.1 Install mode firmware?

According to the release note for 17.9.x code, if you are on 17.3.4 you must go to 17.3.5 then to 17.9.x.
