DNAC Offline Upgrade

[aliamiri53]

Hi folks,

I'm wondering is there a method to upgrade DNAC software offline?

If no, what will be the solution for fully isolated and private networks?

Now DNAC software releases are accessible for download in Cisco accounts with appropriate support contract activated, so what's the usage of that big iso images? Are they useful for upgrading or only fresh installation?

Thanks for your help.

For Offline (Airgap) Installs & Upgrades, you will need to open a Cisco TAC Case and request the ISO & Binary files for the Airgap process. After you open the Cisco TAC case, a request needs to be submitted to the Engineering Team for your Aigap Request. Once it is approved, the TAC engineer will post the images for you to download.

The ISO files on software.cisco.com are mainly used for Disaster Recovery where you need to rebuild the Cisco DNA Center Appliance. This are not used to Upgrade. Outside the Airgap Upgrade process, the only supported upgrade for an existing Cluster is from the Cisco DNA Center AWS Repository.
