Migrating from Supervisor-1 Modules to Supervisor-2 Modules Send documentation comments to [email protected] Migrating from Supervisor-1 Modules to Supervisor-2 Modules As of Cisco MDS SAN-OS Release 3.0(1), the Cisco MDS 9509 and 9506 Directors support both Supervisor-1 and Supervisor-2 modules. Supervisor-1 and Supervisor-2 modules cannot be installed in the same switch, except during migration. Both the active and standby supervisor modules must be of the same type, either Supervisor-1 or Supervisor-2 modules. For Cisco MDS 9513 Directors, both supervisor modules must be Supervisor-2 modules. Caution Migrating your supervisor modules is a disruptive operation. Note Migrating from Supervisor-2 modules to Supervisor-1 modules is not supported. To migrate from a Supervisor-1 module to a Supervisor-2 module, refer to the step-by-step instructions in the Cisco MDS 9000 NX-OS Release 4.1(x) and SAN-OS 3(x) Software Upgrade and Downgrade Guide.
