Section 2203. Cases carried over

All  actions  and  proceedings  pending in any court to which this act
  applies, at the time this act takes effect, shall remain  in  the  court
  and shall be governed by the following subdivisions of this section.
    (a) No such action or proceeding, or appeal taken therein, shall abate
  by virtue of the application of this act to the court.
    (b)  For  the  purpose  of  the  disposition of such pending action or
  proceeding only, the jurisdiction of the court shall be deemed  expanded
  to  that of the court under provisions applicable prior to the effective
  date of this act whenever necessary to sustain the jurisdiction  of  the
  court  over  such  action or proceeding if the court had jurisdiction of
  the same under such provisions.
    (c) Except as provided for in the foregoing, practice and procedure in
  such actions and proceedings shall be as if  the  same  were  instituted
  after the effective date of this act. But if the court shall find that a
  practice or procedure available prior to the effective date of this act,
  but   unavailable  after  such  effective  date,  is  necessary  to  the
  disposition of such action or proceeding, the court may permit  recourse
  to or completion of the same.
