The link is not reachable.

However, I have upgraded stacked 9300 earlier. You need to

1. download the IOS first from the Cisco. 

2. Copy into a flash usb (FAT32 formatted)

3. Plug it into 9300 switch front usb port

4. Copy the image from USB to Flash-1 & Flash-2 (if stack of 2)

5. Boot from flash with newly uploaded image
Let me know for any difficulties.

the url says after copying the firmware do this commands
#software install file flash:cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EX3.bin switch 1-2
will this work?

software install file flash:cat3k_caa-universalk9.SPA.03.03.01.SE.150-1.EX3.bin switch 1-2   <-- do not use this one this is for old firmware.

if you like to upgrade from Everest to Fuji

follow below guide :

int the section clear instructions : ( make sure you take a backup of the config, and read the release notes before the upgrade)

do this in a maintenance window, since stack required a reboot. 

Supported starting from Cisco IOS XE Everest 16.6.2 and later releases

Not Required, I guess. By default it will install the image.
Two type of Cisco Boot mode:
Install Mode/Bundle Mode.
Install mode is the default.

Just change boot system flash:. Save the config and then
reload the switch.

Note: Do not forget to check whether image file is copied to both flash or
not.

dir flash-1
dir flash-2

HI,

I am trying to do the same with a three switch stack,  can you let me know what the commands are to upgrade three switches.

Thanks

1.  Before you start, make sure to clean up the flash with the following command:

request platform software package clean switch all

2.  Use the following command to unpack the firmware with the following command: 

request platform software package install switch all file flash:IOS_filename.bin on-reboot new auto-copy verbose

3.  After the firmware has unpacked the files, use the following command to verify the package.conf contains the correct files:

more flash-X:packages.conf | begin rp_boot

NOTE:  Make sure to run this command on every member of the stack.

4.  Make sure the boot variable string is pointing to the packages.conf:

sh boot

5.  Schedule a reboot:

reboot at <hour>:<minutes> <day> <month>

6.  After the switch has successfully rebooted, do not forget to clean the flash:

request platform software package clean switch all

Good luck and hope this helps.

Hey Leo, given the instructions in your response to upgrading a stack of (3) 9300's, you didn't identify which member to do this on. Does each member require the same procedure, or can your instructions be performed on the Active member, which will then perform the upgrade to the remaining 2 members?

The PDF you attached (thank you for that) also does not directly state how each member is updated. I am making the assumption that the Active stack member copies and performs the upgrade on the other members, but I'm hoping you'll clarify exactly how to handle the upgrade on all members. Thank you in advance.

This procedure is done on the Switch Master. 

The process will also be responsible with "distributing" the BIN file to all the switch members.  

Once the BIN file is present in all the switch members, the unpacking of the PKG files starts.

Read the Release Notes to 16.9.X carefully.
The Release Notes has detailed steps on how to upgrade the firmware to 16.9.X.
IMPORTANT: Upgrade using Install Mode. Bundle mode is not a recommended "long term" method of upgrade.
