Data migration is the process of migrating data from one location to another. It is not something new to the storage industry. Almost every IT organization has had to move data at some point or the other. There are different reasons for doing so: hardware gets obsolete and has to be upgraded, data gets bigger and cannot be handled by the array, the environment is being relocated, etc. As data becomes more complex and difficult to manage, the process of migrating data has taken on a life of its own. Consulting services organizations have made a business out of it. Data migration is no longer about knowing the technology, but about managing the process properly, in a manner that meets the requirements of your internal and external customers. Typical requirements include minimum downtime, (who likes downtime these days, anyway?) reconfiguration of any affected component, and the availability of resources and skills to adequately perform the migration. Whatever the reason may be, there are specific aspects of a data center move that need to be addressed to ensure success.
