So I am starting the 200 to 400 amp upgrade this week, and as I was strategizing last night, I realized I am not sure how to handle the copper ground.
I have 20' of solid copper line and two grounding rods.
I noticed the 400 amp meter socket has a spot for 3 copper grounding cables.
Do I run a solid copper wire from each 200 amp panel in the house to the Meter socket, and then from the MS to the two grounding rods, ensuring I do not splice it?
I ask because when I did this at my parents house (different county) and only a single 200 amp service, we ran the copper wire from the panel to the grounding rods, the meter socket never came into play.

The grounding electrode conductors, sized per 250.66, should originate at the meter or main breakers.
