The DA will always see your entire driving history and prior convictions and try to increase the punishment, but if it's been 10 years since your last conviction, the old ones "wash out" and do not increase the punishment under the applicable statutes.
Just how much your past will affect your case - that depends on the particular facts of the case and your blood alcohol level.
Keep in mind that you have the 10 day window to contest your license suspension with the DMV.
