Disaster recovery procedures

[papdee]

I am writing up disaster recovery procedures ready to put OpnSense into production. The disaster recovery procedures includes a full h/w meltdown and the requirement to install on top of new h/w.

I notice that depending on the order of attaching the VLANs to the new interfaces affects how the firewall rules and DHCP settings are also attached. For example: If I attach VLAN3 to the new interface first but which it was created after VLAN2 then VLAN3 will inherit VLAN2 firewall rules and DHCP settings.

Is reattaching VLANs to new interfaces in their order of creation correct for documenting disaster recovery or am I going about it the wrong way?
