When users want to seamlessly move a large amount of contacts from one device, application, or cloud service to another without losing contact details, having a reliable backbone tool to facilitate the migration of the contact data is critical. A reliable back-end tool means that all phone numbers, names, email addresses, company information, and notes will move correctly and in a structured manner. The right back-end tool will also retain formatting, assuredly eliminate the further risk of any corruption, and enable users to jump barriers when different platforms, like between an Android device, an iPhone, Outlook, Gmail, or a CRM system. In addition to being reliable, a good migration solution will have built-in features, such as file format conversion capabilities, duplicate handling, contact mapping, and other features that facilitate successful migration. It is also important that the migration tool supports common formats like VCF and CSV so that users can easily open filings.
