I have a new vary larg adittion to my house .I put a 200 amp sub in the addition and i wanted to turn the exsisting 100 amp in the house in to a sub.

If the meter and main distribution panel is not at the house then you cannot feed the house with 2 feeders. (art. 225.30) If the 2 main panels are attached to the house then you run more than one feeder to the sub panels.

sounds like the new meter can gets 2 - 200a disconnects to it. one 200 will be an 8/16 with a 100a breaker and ser to the house panel. the other 200a feeds the addition. neutrals bonded at service and seperated from grounds at all other panels.
