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 Fabric Manager 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:
Module
------
At a minimum, you need to disable the default device alias distribution feature using the no device-alias
distribute command in global configuration mode. The show incompatibility system
bootflash:1.3(x)_filename command determines which additional features need to be disabled.
