Step 5
After the supervisor 3E module is online, the configurations are copied to the supervisor 3E module.
Sup2E syslogs
<Thu May 16 01:36:43 2019> Standby Supervisor-3 (N77-SUP3E) has come online, configs
will be copied

Step 6
System switchover is then initiated. This process moves the supervisor 3E module from the HA-standby mode to Active
mode. The SSH/telnet session is disconnected during the switchover. You have to then reconnect to the SSH/telnet session.
Also, ensure that the console link and the management link is connected to the newly inserted supervisor-3E module.

Step 7
After the switchover to the supervisor 3E module is completed, the boot parameters are set for the supervisor migration
process. Do not set any configuration parameters until the boot parameters are set. After the boot parameters are set, the
migration process is complete. Use the show boot command to display the current boot variables and the show module
command to display the modules installed in the switch.
