jQuery Migrate is a feature available for Java users. It is available with the jQuery library, which is in-built. As the jQuery library is well known to be large in size, it requires the use of jQuery Migrate for more ease. It provides ease by reducing the time and effort involved in upgrading the jQuery versions. It helps by adding the eliminated APIs. It makes the user aware of the various faults in the browser and ensures that the code remains unaffected. Thus, it helps users bring in new features without compromising the old features that have been added or used. Hence, jQuery Migrate is recognized for its efficiency in code compatibility. It is optimal for use with versions older than 1.9.
