Migration Assistant is a utility in Mac that allows you to transfer data, apps, settings, user accounts, and documents from Mac to other computer or an external drive connected to the Mac. Currently, the application transfers only limited data; however, the Migration Assistant in the new macOS Mojave will transfer third-party data such as Outlook files. Even though the Migration Assistant is a highly useful application for file-transfer, there are instances of migration errors that result in loss of important data. Later, in this blog, we shall discuss about recovering data lost during file transfer.
