Known Affected Releases

DNAC1.2.12 DNAC1.3.1.6

Description (partial)

Symptom:
An upgrade to Cisco DNA Center from 1.2.12.1 to 1.3.1.6 may hang at 75%, because updating the underlying MongoDB service failed.  While this is going on, the kube-dns service will not be stable, the dnsmasq container will restart continuously, and MongoDB name resolution will fail at 75%.

Conditions:
This was observed during an upgrade from Cisco DNA Center 1.2.12.2 to 1.3.1.6.  Previously, more than 2 DNS servers were configured across 3 interfaces in the cluster.
