Hello there,
We have a ISR4351 with this IOS Software Version,
Cisco IOS XE Software, Version 03.16.04b.S - Extended Support Release
Cisco IOS Software, ISR Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.5(3)S4b, RELEASE SOFTWARE (fc1)
Please advise how to have the ISR4351 upgraded to Version IOS-XE – 17.2.1r.
Thank you, Anand

Personally i do not believe you can go directly from 3.16 i guess
you need to go 16.X then 17.X
read the release notes :

WARNING: You do understand that 17.2.1r and 17.2.2 is an "open beta" version, right? Translation: Whoever is going to load this into production network is going to be "helping Cisco find bugs".
1. It is not possible (nor recommended) to load 17.X.X without upgrading the ROMMON.
2. Read the Release Notes carefully.
3. Copy the file into the appliance.
4. Initiate Install Mode:
request plat soft package expand file bootflash:<FILENAME>.bin over verb
5. Change the boot variable string to point to "packages.conf".
conf t no boot system flash bootflash:<OLD_IOS>.bin boot system flash bootflash:packages.conf boot system flash bootflash:<OLD_IOS>.bin end wr
6. [OPTIONAL] Upgrade the ROMMON to 16.12.(2r) (ROMMON file can be found HERE
upgrade rom-monitor filename bootflash:isr4200_4300_rommon_1612_2r_SPA.pkg all
NOTE: Check to see if ROMMON is required using the following command:
sh platform
Look at the last 3 lines on the bottom of the page.
7. COLD REBOOT (pull the power cable).
IMPORTANT: When dealing with IOS-XE, perform COLD REBOOT as often as possible. I cannot discuss why any further than this.
