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. For Cisco MDS 9513 Directors, both supervisor modules must
be Supervisor-2 modules.

Migration Guidelines
Before performing the migration procedure, consider the following guidelines:
•
Both Supervisor-1 and Supervisor-2 modules must be running the same SAN-OS release during
migration.

•
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.

•
To ensure high availability, you must connect the Ethernet port for both active and standby
supervisors to the same network or virtual LAN. The active supervisor owns the IP address used by
these Ethernet connections. On a switchover, the newly activated supervisor takes over this IP
address.

Migrating from Supervisor-2 modules to Supervisor-1 modules is not supported.

The procedure described in this section ensures that your configuration is correctly synchronized
after completing the migration.
after completing the migration.
Caution
Migrating your supervisor modules is a disruptive operation. The disruption occurs at the time of the
switchover. When the Supervisor-2 module is plugged into the chassis and it comes up as the standby, it
is in a warm standby mode (only the ASCII configuration is synchronized; global synchronization is not
performed). When the switchover is initiated from the active Supervisor-1 module, the Supervisor-2
module takes over as the active supervisor and applies the ASCII configuration on the switch. At this
time, all modules in the chassis are powered down and brought back up as if a fresh boot occurred. The
Supervisor-1 module gets powered down.
