The "coordinate transformation between the ellipsoids" before the upgrade corresponds to the escalation of the "boolsa model", and the "multi common point similarity transformation" before the upgrade corresponds to the "two-dimensional four parameter model" after the upgrade. The conversion parameters before the two models can be used for the upgraded software. Only the "scale ratio" is converted into a "scale change", and the conversion formula is that the scale change D= scale is compared with K-1.
