Nondisruptive software upgrades or downgrades between NPE images and non-NPE images are not supported.

This section lists the guidelines recommended for upgrading your Cisco MDS NX-OS software image and includes the 
following topics:

Before you begin the upgrade process, review the list of chassis and modules that Cisco MDS NX-OS 
Release 6.2(11) supports. See the 

.

For detailed instructions for performing a software upgrade using Cisco DCNM, see the Cisco DCNM Release Notes, Release 
6.2, which is available from the following website:

Follow these general guidelines before performing a software upgrade:

Review the nondisruptive upgrade path to Release 6.2(11) in 

Install and configure dual supervisor modules before the upgrade. 

Issue the show install all impact upgrade-image CLI command to determine if your upgrade will be nondisruptive.

Be aware that some features impact whether an upgrade is disruptive or nondisruptive:

Fibre Channel Ports: Fibre Channel ports can be nondisruptively upgraded without affecting traffic on the ports. See 

 for the nondisruptive upgrade path for all NX-OS and SAN-OS releases.

Gigabit Ethernet Ports: Traffic on GigabitEthernet/IPStorage ports is disrupted during an upgrade or downgrade. 
This includes the Gigabit Ethernet ports on the MSM-18/4 module, the MDS 9222i switch, the MDS 9000 16-Port 
Storage Services Node (SSN-16), and the IPStorage ports in MDS 9250i. Those nodes that are members of VSANs 
traversing an FCIP ISL are impacted, and a fabric reconfiguration occurs. iSCSI initiators connected to the Gigabit 
Ethernet ports lose connectivity to iSCSI targets while the downgrade is in progress.

FICON: If you have FICON enabled, the upgrade path is different. See the 

.

In addition to these guidelines, you may want to review the information in the 

 section prior to a software upgrade to determine if a feature may possibly behave 

differently following the upgrade.
