• Do not:
– insert or remove any transceivers from any modules while the migration is in progress.
– alter any connections while the migration is in progress.
– remove any power supply modules or fan modules during the migration process.
– attempt any configuration changes or network changes while the migration is in progress.
– copy any configurations using the copy running-config startup-config command while the migration is
in progress.
– trigger any EPLD or BIOS upgrades during the migration.
– trigger any ISSU during the migration.
– perform migration from Crossbar Fabric-1 Switching Modules to Crossbar Fabric-3 Switching Modules
during the Supervisor-1 Module to Supervisor-4 Module migration.
Prerequisites
• 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
