Prerequisites and Guidelines
![]() Note |
If you are already running Nexus Dashboard with Fabric Controller service, skip this section and upgrade as described in Upgrading Existing ND Cluster to This Release instead. |
Upgrading from DCNM 11.5(4) consists of the following workflow:
-
Ensure you complete the prerequisites and guidelines described in this section.
-
Back up your existing configuration using a migration tool specific to the target NDFC release.
-
Deploy a brand new Nexus Dashboard cluster with Fabric Controller (NDFC) service.
Note that unlike in previous releases where you had to install the service and enable it after the cluster was already deployed, in this release you enable the service during initial cluster deployment due to the introduction of the unified installation.
-
Restore the configuration backup you created in step 1.
