Determining the Software Version
To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS
9000 Family switch using the CLI, log in to the switch and enter the show version EXEC command.
To determine the version of Cisco MDS NX-OS or SAN-OS software currently running on a Cisco MDS
9000 Family switch using Cisco DCNM for SAN, view the Switches tab in the Information pane, locate
the switch using the IP address, logical name, or WWN, and check its version in the Release column.
Determining Software Version Compatibility
Table 10 lists the software versions that are compatible in a mixed SAN environment, the minimum
software versions that are supported, and the versions that have been tested. We recommend that you use
the latest software release supported by your vendor for all Cisco MDS 9000 Family products.
Downloading Software
The Cisco MDS NX-OS software is designed for mission-critical high availability environments. To
realize the benefits of nondisruptive upgrades on the Cisco MDS 9500 Directors, we highly recommend
that you install dual supervisor modules.

See the following sections in this release note for details on how you can nondisruptively upgrade your
Cisco MDS 9000 switch. Issuing the install all command from the CLI, or using Cisco DCNM for SAN
to perform the downgrade, enables the compatibility check. The check indicates if the upgrade can
happen nondisruptively or disruptively depending on the current configuration of your switch and the
reason.
Compatibility check is done:
