Why do we need data migration software?

Generally speaking, data migration is a process of selecting, preparing and transferring data from one storage location to another, from one computer storage system to another. It is a great way to make a data backup.

When it comes to moving data, the most common method is “Copy & Paste”, which works fine for a small amount of data. But if the data takes up too much space, like system files or big programs, things will become very tough since you need to individually install them again. It would be a long and tedious process. So a professional data migration software is quite necessary. That can simplify the process and make it more efficient and convenient.
