Hello Rene,
First, i want to thank you once again for explaining technologies in plain english. This is so much fun reading your posts after all the articles in the internet which poses more confusion.
However i have a question. According to Cisco APIC-EM is end of life (https://www.cisco.com/c/en/us/products/collateral/cloud-systems-management/application-policy-infrastructure-controller-enterprise-module/eos-eol-notice-c51-741252.html) and the replacement product is DNA Center Appliance.

Could you please confirm or correct me if i am wrong ?
Thanks again for your great posts.
Oliver
