moved states, how do I file state taxes?

I moved from CA to OR in august, but continued to work for the same company.

 

I recieved 3 w-2s

 

The first one has the same the amount I earned while working in CA

 

the next ones seem to be copies of the same one of the income I earned while in OR

the only difference is 

 

1:

15:

STATE ID:TOTAL STATE

16:

17: $xxx.xx (state income tax I paid while working in oregon)

 

w2 #2

15 CA (california state ID)

16 xxxx.xx (ammount I made while workin in OR)

17 blank

 

So how do I file that all the income under california since it doesn't mention OR or?
