Step 1 Copy the Cisco NX-OS Release 8.4(1) kickstart and system images to the active supervisor module bootflash, using an
FTP or TFTP server.
switch# copy tftp://tftpserver.cisco.com/n7700/n7700-s3-kickstart.8.4.1.bin bootflash:n7700-s3-kickstart.8.4.1.bin
switch# copy tftp://tftpserver.cisco.com/n7700/n7700-s3-dk9.8.4.1.bin bootflash:system n7700-s3-dk9.8.4.1.bin
Step 2 Use the migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image> command in config mode to
initiate the migration process. This command triggers image version compatibility checks before initiating the migration
process to ensure that the image being used is compatible with the supervisor 3E module.
• A message then appears on the console asking for confirmation to continue the migration procedure. Type Yes on
the console prompt to continue with the migration procedure.
• Configuration commands are now blocked. The migrate sup kickstart <sup3-kickstart-image> system
<sup3-system-image> command will then check if it has to initiate a single supervisor or dual supervisor migration
process by checking if there is a standby supervisor 2E module installed in the switch.
• The migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image>command will power down the
standby supervisor 2E module installed in the switch.
• You can use the show modulecommand to display the modules installed in the switch.

This will start the Supervisor-2 to Supervisor-3 migration. Configuration will be locked until
migration is complete.

<Thu May 16 01:10:11 2019> Starting migration, Please do not remove any linecards or fabric
cards until migration is complete
<Thu May 16 01:10:11 2019> Standby supervisor in slot 3 has been powered down
Step 3 After the standby supervisor 2E module is powered down, remove the standby supervisor 2E module from the slot and
replace it with the supervisor 3E module, as explained in the Installing or Replacing a Supervisor Module section. When
the supervisor 3E module is detected in the standby supervisor slot, a netboot is initiated with the image that is provided
by using the migrate sup kickstart <sup3-kickstart-image> system <sup3-system-image> command.
