Restore Licenses
Issue the license import command in the command-line interface or click Import Database in the
Configuration > Network > Controller > License Management page of the WebUI to import licenses
from the license database to the new controller.
(host) #license import <filename>
Do not save the configuration or write to memory at the end of this step.
Reboot the Controller
Once all the licenses have been restored, issue the reload command in the command-line interface or navigate
to Maintenance>Reboot Controller in the WebUI to reboot the new controller. After rebooting, the
controller should not be on the network (or a reachable subnet) with the controller it will replace. This is to
prevent a possible IP address conflict.
Do not save the configuration or write to memory at the end of this step.
(host) #reload
Do you want to save the configuration(y/n): n
Do you really want to restart the system(y/n): y
System will now restart!
Modify the Host Name
Issue the hostname command in the command-line interface to give the new controller a unique hostname.
(The flash restoration process gave the new controller the same name as the existing controller.)
Do not save the configuration or write to memory at the end of this step.
(host)(config) #hostname <hostname>
Modify Topology Settings
This is required when migrating to a newer controller model. New controller models such as the W-7000 Series
and W-7200 Series controllers use a different port numbering scheme than other Dell controllers. Ports on the
newer controller models are numbered slot/module/port. Older controller ports are numbered slot/port. As
a result, flash backup files restored from older controllers onto a newer model controllers can cause the newer
controller lose network connectivity, as the imported port settings don't match up with the controller
hardware. Additionally, all ports will become untrusted when you import a configuration from an older model
controller to a newer model controller.
Use the interface range and switchport commands to reconfigure the VLANs and IP interfaces to match the
port scheme of that hardware model. To avoid network conflicts, this process must be completed before the
controller is connected to the management network.
If you are replacing a controller with the same controller model, you can skip this step and continue to Save your
Configuration on page 49
The following commands adjust the port configuration on the new controller .
(host) (config) #interface range gigabitethernet <slot>/<module-start>/<port-start>-<module-
end>/<port-end>
(host) (config-range) #switchport access vlan <id>
