Question - Configuring two DHCP server

Hello all,

I've been using a DHCP server for long time, and configuration is in place and working (This is an SRX in Chassis cluster). Now I want to use a new DHCP server but only for 2 interfaces as a test before full rollout, and want to see if the following configuration looks accurate:

Current config:

set forwarding-options dhcp-relay server-group DHCP_SERVER 10.172.26.17
set forwarding-options dhcp-relay active-server-group DHCP_SERVER
set forwarding-options dhcp-relay group CORPORATE_V1001_DHCP_RELAY interface reth1.1001
set forwarding-options dhcp-relay group CORPORATE_V1002_DHCP_RELAY interface reth1.1002
set forwarding-options dhcp-relay group CORPORATE_V1003_DHCP_RELAY interface reth1.1003
set forwarding-options dhcp-relay group CORPORATE_V1004_DHCP_RELAY interface reth1.1004
set forwarding-options dhcp-relay group VOICE_V1101_DHCP_RELAY interface reth1.1101
set forwarding-options dhcp-relay group VOICE_V1102_DHCP_RELAY interface reth1.1102
set forwarding-options dhcp-relay group VOICE_V1103_DHCP_RELAY interface reth1.1103
set forwarding-options dhcp-relay group VOICE_V1104_DHCP_RELAY interface reth1.1104

New config:

set forwarding-options dhcp-relay server-group DHCP_SERVER 10.172.26.17
set forwarding-options dhcp-relay server-group BLUECAT_SERVER 8.8.8.8
set forwarding-options dhcp-relay active-server-group BLUECAT_SERVER
set forwarding-options dhcp-relay group CORPORATE_V1001_DHCP_RELAY active-server-group BLUECAT_SERVER
set forwarding-options dhcp-relay group CORPORATE_V1001_DHCP_RELAY interface reth1.1001
set forwarding-options dhcp-relay group CORPORATE_V1002_DHCP_RELAY interface reth1.1002
set forwarding-options dhcp-relay group CORPORATE_V1003_DHCP_RELAY interface reth1.1003
set forwarding-options dhcp-relay group CORPORATE_V1004_DHCP_RELAY interface reth1.1004
set forwarding-options dhcp-relay group VOICE_V1101_DHCP_RELAY interface reth1.1101
set forwarding-options dhcp-relay group VOICE_V1102_DHCP_RELAY interface reth1.1102
set forwarding-options dhcp-relay group VOICE_V1103_DHCP_RELAY active-server-group BLUECAT_SERVER
set forwarding-options dhcp-relay group VOICE_V1103_DHCP_RELAY interface reth1.1103
set forwarding-options dhcp-relay group VOICE_V1104_DHCP_RELAY interface reth1.1104

I'm just not sure what exactly the "active-server-group" option does, and what is the correct way to specify different DHCP servers for each interface.

Thanks!
