In a Cu and Fe electroplaying process, why does the positively charged ions move from Cu to Fe instead of the other way round?

I think the basic answer though is that copper dissolves more easily than iron and so it becomes a positively charged ion in solution and migrates toward the iron electrode.
Electroplating is a process in which a metal object is coated with a thin layer of another metal using electricity. This is achieved by immersing the object in a solution containing ions of the desired coating metal, and then passing an electric current through the solution.
The purpose of electroplating is to improve the surface properties of an object, such as its appearance, corrosion resistance, and durability. It is also used to create a desired aesthetic, such as a shiny or reflective finish, or to increase the conductivity of a material.
The steps involved in electroplating include cleaning and preparing the object to be plated, creating a solution of the desired coating metal, immersing the object in the solution, and passing an electric current through the solution. This causes the metal ions to deposit onto the object, forming a thin, even layer.
Any metal that can conduct electricity can be used for electroplating, but the most common metals used as coatings are gold, silver, nickel, copper, and chrome. Other metals, such as zinc, tin, and platinum, can also be used for specific applications.
The advantages of electroplating include improved surface properties, increased durability and corrosion resistance, and the ability to create a desired aesthetic. However, the process can be expensive and time-consuming, and can also have negative environmental impacts if not properly managed.
