Cisco Firepower FPR1120 Upgrade Issue - DNS

Smitster1 — Sun, 23 Jun 2024 14:07:24 GMT

Hi,

I am currently trying to upgrade the system of a Cisco Firepower FPR1120 from version 7.0.4-55 to the latest stable release 7.2.5-208. Precheck passess successfully however when implementing the upgrade I get the following upgrade error "Fatal error: A maximum of two IPv4 and two IPv6 DNS servers is allowed."

I understand this is currently covered under the Cisco bug here

https://bst.cisco.com/quickview/bug/CSCwf68616

However, i've reviewed the dns settings on the FDM and I can only see two addresses configured unuder System Settings -> DNS Server (the default CiscoUmbrellaDNSServerGroup)

I'm unsure what other config settings need updating to allow this upgrade to proceed. What am I missing?

Thanks,
