I've identified the issues with the upgrade (by going back to the old version and seeing what was not carried over transferrred).

• Condiional forwarding is not copied.
• Never forward non-FQDN A and AAAA queries**
• Upstream DNS Server
• lighttpd was not stopped and removed
• local DNS records not copied
• dns_masq.d not copied (which can be corrected by a setting)

Once I corrected these 4 issues I was able to return to operating as normal
