Hi,

I would suggest you to change the boot priority of the switch if it is having two IOS.

switch(config-t)#boot-start-marker

switch(config-t)#boot system flash: new IOS

switch(config-t)#boot system flash: old IOS

switch(config-t)#boot-end-marker

switch(config-t)#do write

Reboot the switch afterward and it should start with the new IOS.

With Regards

Hi Jahan, 

That is now how you upgrade the 3850 model.
The 3650 and 3850 has a different way to upgrade the switch

Before proceeding, verify what boot type your switch uses. Most of what I encounter are "Install mode"

Anyway, follow steps below:

1. Verify Install type
#dir flash:
#show version

**IF:
A. INSTALL MODE
1. *.pkg files are present
2. DO: #show version
LOOK FOR: System bundle file is:
DISPLAYS: "flash:packages.conf"

B. BUNDLE MODE
1. *.bin file only
2. DO: #show version
LOOK FOR: System bundle file is:
DISPLAYS: <Another file compared to the file mentioned above>


Once you have verified the install type, proceed with the proper firmware update.

Again, please consider what your switch is currently set to: Either Install mode and Bundle mode 
All the instructions should be on the link i provided :)
