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.

in the Cisco MDS 9000 NX-OS Release 4.1(x) and SAN-OS 3(x) Software Upgrade and Downgrade
