Database migration has become a routine operation in most IT organizations for modernization, consolidation and platform migration. Migration delivers improved computing power, faster performance, new functions, features, and lowered cost of ownership. But this essential operation invites a lot of risks as well as long operational outages. Migrating Oracle database presents many unique challenges for IT administrators; such as the complexity, data integrity requirements, and 24x7 availability requirements of critical database applications. To address these challenges, Dell offers a near zero downtime migration strategy to move Oracle databases into a new infrastructure with near zero downtime impact. This methodology has been proven to be reliable and repeatable with the adoption by Dell IT for a large scale Oracle database migration project. This methodology brings out the best of Dell Compellent storage features like thin provisioning and a well tested reference architecture using the latest generation Dell PowerEdge servers.
