Prerequisites

Ensure that you have completed all of the prerequisite preparation before migrating.

  • Ensure that you have network-admin role privileges to migrate the supervisor modules. 
switch# show user-account admin
user:admin
this user account has no expiry date
roles:network-admin
  • The minimum supported release for this procedure is NX-OS Release 8.4(1). If you are using an image older than NX-OS Release 8.4(1), upgrade to NX-OS Release 8.4(1), and then perform the nondisruptive migration from a Supervisor-1 Module to aSupervisor-4 Module. To upgrade an image version on the switch, refer the 9000 NX-OS Software Upgrade and Downgrade Guide, Release 8.x guide.
  • We recommend that you use a console connection to perform the migration procedure. In case you do not have a console connection and are using an SSH/Telnet connection, use the terminal monitor command to display all the syslogs mentioned in the below procedures.
  • Back up the running configuration from the current active supervisor module to the FTP/SFTP/TFTP server, or a USB flash drive.
switch(config)# copy running-config
ftp:[//[username[:password]@]server][/path]

Or, 

copy running-config usb1:runningconfiguration.txt
Copy complete, now saving to disk (please wait)...
Note: runningconfiguration.txt is a filename variable.
  • Back up the required files from the bootflash of the current active supervisor module to the FTP/SFTP/TFTP/SCP server, or a USB flash drive. 
switch(config)# copy bootflash:userfile.txt scp://root@x.x.x.x/root/userfile.txt
Note: userfile.txt is a filename variable.
  • Back up 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# show license
license.lic:

switch()# copy licenses usb1:licenses_archive_file_name.tar
Note: You must use the tar extension for the archive file. This file contains all the license files that are installed on the Supervisor-1 Module.
  • Back up the outputs of the show tech-support details command, and redirect the file to a remote server using an FTP, TFTP, SFTP, SCP, or a USB flash drive.
switch# show tech-support details> scp://root@x.x.x.x/root/showtechsupport.txt

Or

switch# show tech-support details> usb1:showtechsupport.txt
  • Replacement supervisor modules
  • Supervisor-4 Module. Two Supervisor-4 Modules for the dual supervisor migration.
  • Ensure that there is enough memory on the boot flash of Supervisor-1 Modules to copy the new software image. To check the boot flash memory, use the dir bootflash: command.
