Yes, Cisco DNA Center (DNAC) aka Catalyst Centre does support a two-step process for updating IOS images on network devices.
Two-Step Process:
Step 1: Push and Validate the Image
Step 2: Activate and Reload

Hello,
I'm just wondering as we have a constant need to upgrade our Cisco switch estate IOS versions due to CareCerts, vulnerabilities, compliance etc. Is there any sort of plan to within the SWIM feature on Catalyst Centre to alert the user that there is a new Cisco recommended gold star image to download for that series of switch model in future releases?

Hey everyone,
quick question: Does SWIM have a timeout? I would be attempting to upgrade images over WAN.

Yes, the SWIM distribution task has a timeout of 600 minutes. If the file is not copied to the device within this period, the distribution task will fail.
When upgrading over WAN, please ensure that network latency is low enough to support a smooth upgrade process.

Are there any pre requisite we need to take care of before we upgrade via SWIM?
06-27-2024 05:05 AM
Before performing an image upgrade, the following pre-requisites should be reviewed.
1. Check the Minimum Software Releases Requirements on Devices
Cisco DNA Center requires the software releases on devices to meet the ones listed in Minimum Supported Software Version column of supported devices spreadsheet below: https://www.cisco.com/c/en/us/support/cloud-systems-management/dna-center/products-device-support-tables-list.html
2. Devices have CLI /SNMP or HTTPS/SCP credentials.
Network devices should be in managed state or the administrators have CLI/SNMP or HTTPS/SCP credentials for Cisco DNA Center to discover them and bring them in managed state before performing a Software Image upgrade. This requirement is only for Day N scenario.
3. CCO Credentials
Though this is not a mandatory requirement for SWIM but its strongly recommended to add CCO credentials. Otherwise, certain features like ROMMON upgrade or suggested and latest image display list of images will not function. CCO Credentials is also required to download the KGV file for Integrity Verification of Software Images.
4. Integrity Verification of Software Images
The Integrity Verification application monitors software images that are stored in Cisco DNA Center for unexpected changes or invalid values that could indicate your devices are compromised. During the import process, the system determines image integrity by comparing the software and hardware platform checksum value of the image that you are importing to the checksum value identified for the platform in the Known Good Values (KVG) file to ensure that the two values match.
