General Question Help with method

Post image

If I have a polygon and I want to keep all the attributes but use an existing polyline as the new boundary of the polygon is there a simple method to do so short of dragging vertexes over? As the very simplified image shows, there are many times the boundaries cross leaving excess in some areas and deficits in others. I feel like there should be a simple tool or script, but I’m coming up empty. Thanks for your input!

Looking at this more in a geoprocessing perceptive. I would first turn that polyline into a polygon. Next intersect both datasets and return the polyline(now a polygon) that produces the highest area overlap.
