Technical Report DTA Migrations Using NetApp DTA2800 Methodology Patricia Tarro, Chip Ray, Pradeep Palukuri, NetApp June 2013 | TR-4061 Abstract This guide is intended to assist SEs/CSEs and PSEs/PSCs in migrating data using a five- phase data migration process designed to handle the most complex migration scenarios while heeding specific customer needs and making sure the right migration strategy is executed for each specific environment. The document describes the steps necessary for a successful SAN data migration from EMC CX700 storage on Windows®, Linux®, and Solaris hosts to NetApp® storage.
