If the migration mode is activated, the changes shown in the tables in the pylon Programmer's Guide are automatically mapped, if a mapping exists.
The migration mode supports writing code when working with multiple camera device types that are compatible with different SFNC versions. However, it is strongly recommended to adapt existing code to be SFNC 2.0 compatible, if you are only working with SFNC 2.0 compatible cameras instead of using the migration mode.
// Access the camera's exposure time with both the old and new name:
GenApi::CFloatPtr exposureTime(
camera.GetNodeMap().GetNode( "ExposureTimeAbs"));
GenApi::CFloatPtr exposureTime2(
camera.GetNodeMap().GetNode( "ExposureTime"));
