Cisco DNA Center provides many of its functions as individual applications, packaged separately from the core infrastructure. This lets you install and run the applications that you want and uninstall those you are not using, depending on your preferences.
However, be aware that application packages are not backward compatible. For example, if you are running base system version 1.2.0, you cannot install the Cisco SD-Access application version 1.2.1. You must first upgrade the base system version to 1.2.1 and then install or upgrade the Cisco SD-Access application to 1.2.1.
The number and type of application packages shown in the Software Updates window will vary, depending on your Cisco DNA Center version and your Cisco DNA Center licensing level. All application packages available to you are shown, whether or not they are currently installed.
Some applications are so basic, they are required on nearly every Cisco DNA Center deployment. For a description of any package and whether it is required, hover over that package's name in the Updates tab.
Each Cisco DNA Center application package consists of service bundles, metadata files, and scripts.
Perform all application management procedures from the Cisco DNA Center GUI. Although you are able to perform many of these same procedures using the CLI (after logging into the shell), this is not recommended. In particular, if you use the CLI to deploy or upgrade packages, you must ensure that no deploy or upgrade command is entered unless the results of the maglev package status command show all packages as NOT_DEPLOYED, DEPLOYED, or DEPLOYMENT_ERROR. Any other state indicates activity in progress, and parallel deployments or upgrades are not supported.
