Cisco 3850 IOS upgrade from 3.x.x to 16.x.x
Cisco 3850 IOS upgrade from 3.x.x to 16.x.x
Motivation:
This manual shows how to upload IOS via FTP or USB disk and upgrade IOS XE for switch Cisco Catalyst (C3850) series.
Implementation [1]:
First we need to make sure that we have available space on flash using command below,
Cat3850#software clean
Output from software clean command:
Preparing clean operation ...
[1]: Cleaning up unnecessary package files
[1]: No path specified, will use booted path flash:packages.conf
[1]: Cleaning flash:
[1]: Preparing packages list to delete ...
In use files, will not delete:
cat3k_caa-base.SPA.03.06.05E.pkg
cat3k_caa-infra.SPA.03.06.05E.pkg
cat3k_caa-iosd-universalk9.SPA.152-2.E5.pkg
cat3k_caa-platform.SPA.03.06.05E.pkg
cat3k_caa-wcm.SPA.10.2.150.0.pkg
packages.conf
Committed files, will not delete:
cat3k_caa-drivers.SPA.03.06.05E.pkg
[1]: No unnecessary package or provisioning files found. Nothing to clean
In this example we are going to use IOS XE called cat3k_caa-universalk9.16.12.08.SPA.bin. IOS image can be downloaded from this pages: https://software.cisco.com/download/home
Example of copy IOS file from FTP server (running under IP address 192.168.1.10) to C3850 series switch:
Cat3850#copy ftp://yourlogin:yourpassword@192.168.1.10/cat3k_caa-universalk9.16.12.08.SPA.bin flash:
or example of copy IOS file from USB disk to C3850 switch:
Cat3850#copy usbflash0:cat3k_caa-universalk9.16.12.08.SPA.bin flash:
MD5 verification:
Cat3850#verify /md5 cat3k_caa-universalk9.16.12.08.SPA.bin
Save running-config to startup-config:
Cat3850#wr
Command below execute software upgrade process. Keyword new is needed to create new packages file that will be used by boot up process. Keyword force that is very important because we are going from one major code version 3.x.x to 16.x.x, this will force the actual upgrade process otherwise the package compatibility check will fail:
Cat3850#software install file flash:/cat3k_caa-universalk9.16.12.08.SPA.bin new force
Output from software install file flash:/cat3k_caa-universalk9.16.12.08.SPA.bin new force command

[1]: Creating pending provisioning file
[1]: Finished installing software. New software will load on reboot.
[1]: Committing provisioning file
[1]: Do you want to proceed with reload? [yes/no]: y
[1]: Reloading
It can take up to 20 mins to come back up because of microcode upgrade.
After switch reload, check version:
Cat3850#show version
Partial output from show version command shows that new version CAT9K IOS XE 16.12.08 is working:
Switch Ports Model SW Version SW Image Mode ------ ----- ----- ---------- ---------- ---- * 1 32 WS-C3850-24S 16.12.08 CAT3K_CAA-UNIVERSALK9 INSTALL
Verify New Packages and Image after reload:
Cat3850#dir flash:*.pkg
Output from dir flash:*.pkg:
