• Ensure that the Supervisor-3E module has not been inserted in the standby slot before using the migrate
sup kickstart <sup3-kickstart-image> system <sup3-system-image> command. If the supervisor-3E
module has already been inserted in the standby slot, the migration process will be aborted and the
supervisor-3E module will be powered down.
• Do not reload or manually insert or remove any I/O or fabric module after using the migrate sup kickstart
<sup3-kickstart-image> system <sup3-system-image> command. Any removal or insertion of I/O or
fabric modules has to be done before initiating the migration process or after the migration is completed.
• Do not remove or insert any Fabric Extender (FEX) modules during migration.
• Insert the standby Supervisor-3E module into the chassis only when you are prompted to insert the
Supervisor-3E module during migration by a message on the system console.
• After the Supervisor-3E module has been inserted during the migration process, do not remove or manually
reload the standby Supervisor-3E module.
• Do not insert or remove any transceivers from any modules while the migration is in progress.
• Do not remove any power supply modules or fan modules during the migration process.
• Do not copy any configurations using the copy running-config startup-config command or the copy
running-config startup-config vdc-all from any other management session while migration is in progress.
• Do not trigger any EPLD or BIOS upgrades during migration.
• Do not trigger any ISSU during migration.
• Do not perform migration from fabric module-2 to fabric module-3 during the supervisor-2E to
supervisor-3E migration.
• Take a backup of the licenses and configuration before starting the migration procedure. In case of any
failure or loss of licenses and configuration in Supervisor-2E, disruptive migration has to be done to
upgrade to Supervisor- 3E. In such a scenario, all configurations and licenses have to be applied or
installed again. Backup the installed licenses from the switch to a USB drive by using the copy licenses
command. To view the current licenses installed on the switch, use the show license command.
switch# copy licenses usb1:<licenses_archive_file_name>.tar
• Ensure that there is sufficient power in the chassis before starting the migration process. In case of a
power failure, redundant power supplies can then take over and migration will not be disrupted.
• Downgrade to supervisor-2E modules from supervisor-3E modules is a disruptive procedure.
Case 1: Dual Supervisor Migration
To perform non-disruptive migration from Supervisor 2E modules to Supervisor 3E modules in a switch that
has both active and standby supervisor modules installed, follow these steps:
Before you begin
The minimum supported release for this procedure is Cisco NX-OS Release 8.4(1). If you are using an image
older than Cisco NX-OS Release 8.4(1), upgrade to Cisco NX-OS Release 8.4(1), and then perform
nondisruptive migration from Supervisor 2E modules to Supervisor 3E modules.
