Just ran a quick debug again so I get my story straight
The key in dhcp_sqlippool is
pool_key = "%{%{DHCP-Client-Identifier}:-%{DHCP-Client-Hardware-Address}}"
Debug is as follows
Tue Oct 28 16:32:24 2025 : Debug: (1121) DHCP-Gateway-IP-Address = 10.180.144.2
Tue Oct 28 16:32:24 2025 : Debug: (1122) DHCP-Gateway-IP-Address = 10.180.144.3
Tue Oct 28 16:32:24 2025 : Debug: DHCP: Existing IP: %{reply:DHCP-Your-IP-Address} (cid %{DHCP-Client-Identifier} chaddr %{DHCP-Client-Hardware-Address} giaddr %{DHCP-Gateway-IP-Address})
Tue Oct 28 16:32:24 2025 : Debug: attribute --> DHCP-Gateway-IP-Address
Tue Oct 28 16:32:24 2025 : Debug: (1121) dhcp_sqlippool: EXPAND DHCP: Existing IP: %{reply:DHCP-Your-IP-Address} (cid %{DHCP-Client-Identifier} chaddr %{DHCP-Client-Hardware-Address} giaddr %{DHCP-Gateway-IP-Address})

Tue Oct 28 16:32:25 2025 : Debug: DHCP: No Pool-Name defined (cid %{DHCP-Client-Identifier} chaddr %{DHCP-Client-Hardware-Address} giaddr %{DHCP-Gateway-IP-Address})
Tue Oct 28 16:32:25 2025 : Debug: attribute --> DHCP-Gateway-IP-Address
Tue Oct 28 16:32:25 2025 : Debug: (1123) dhcp_sqlippool: EXPAND DHCP: No Pool-Name defined (cid %{DHCP-Client-Identifier} chaddr %{DHCP-Client-Hardware-Address} giaddr %{DHCP-Gateway-IP-Address})

These are the same request being relayed from the two different routers. One matches the existing ip the other does not as the query is using the giaddr. Unless I am misunderstanding the debug.

You can upgrade on a test machine. And see if the queries have been updated.

And.... what does the debug output say?
