(a) Effective Date. The Probate Code shall take effect on July 1, 1949, except that, when its application, or parts thereof, would not be feasible or would work injustice in particular proceedings then pending, the former procedure shall apply.
(b) Rights Not Affected. Acts done and rights accrued prior to July 1, 1949, shall not be affected or impaired by its provisions. When a right is acquired, extinguished, or barred upon the expiration of a prescribed period of time which has commenced to run by the provision of any statute in force before the Probate Code takes effect, the provision shall remain in force and be deemed a part of the Probate Code with respect to such a right.
