Step 1 – Copy the new image to the 3850
Note that you can use the copy command using a specific VRF:
copy tftp flash vrf Mgmt-vrf Address or name of remote host [10.200.1.11]? Source filename [cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin]? Destination filename [cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin]? Accessing tftp://10.65.113.11/cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin... Loading cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin from 0.200.1.11 (via GigabitEthernet0/0): !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! [OK - 328618032 bytes] 328618032 bytes copied in 1486.160 secs (221119 bytes/sec)
Once the image is done copying onto the switch, verify it:

Step 2 – Start the install
Notice that I’m doing TWO switches in the stack since this stack only has two switches. This command will upgrade all the switches in the stack. Make sure your numbers are correct here.
software install file flash:cat3k_caa-universalk9.SPA.03.07.05.E.152-3.E5.bin switch 1-2
