Many thanks! Since I didn’t manage to get it done, I repurposed the DNAC as a firewall — a second life.

Hi,
Within the following document, section "Update the Cisco IMC firmware" gives you all requirements you need to go through.
Som good details on the actual CC upgrade process can be found within this Cisco Live presentation:

Thanks,
Cristian.
