Migrating SteelHead settings with the SCC
You generally use the migrate operation to move the state of an existing appliance to the replacement appliance. The migrate operation moves the state statistics, SCC configuration, and snapshots from one SteelHead (referenced by serial number) to another. After you’ve a successful migrate operation, the new SteelHead is managed by the SCC and the source settings are deleted.
You can’t perform a migrate operation between SteelHead and SteelHead EX.
For complete migration procedures, see the SteelCentral Controller for SteelHead User Guide.
