This will work. What you're doing though, is "play-testing"
the boot order once and relying on it not to change, and

A more solid way to do this, may be to assign ip address
using dhcp based on the mac address (fixed dynamic). This
gives you a slot to ip address fixed ordering and in a way
takes eth0/eth1 out of the picture. As long as you know
that bottom nic is ip address x, and top nic is ip address
y, then you can plan the switchover procedure.
At this point I think it shouldn't really matter which is
eth0, which is eth1.
