The cloud offers companies many key advantages: easier scalability, greater flexibility and storage space, lower costs and better performance. Those who want to make things easy for themselves migrate all their available company data. This is not always the wisest thing to do, however, especially since storage and data capacity play a decisive role in the composition of migration costs. Therefore, the first step in data migration should be to know your data inside out. Storage vendors and migration service providers may have the tools to move data, but companies themselves need to know what data should go where, and what doesn’t need to be kept at all.
