The Evolution of Data and Database MigrationLarge-scale projects such as multiple site mergers, green IT initiatives, Virtualization projects, database server consolidation, and technology refresh cycle are common in the database world. A common theme across all of these is data migration. From a database management perspective, data migration has traditionally been treated as an exception to normal operations. Data migration also appears to coincide with unforeseen challenges that result in extended downtime and the need to cancel, cancel, and defer activity. In larger environments, data migration is no longer an intermittent distraction but a regular activity that consumes a growing number of organizations. hours.

Choosing the right approach is highly dependent on infrastructure limitations, data types and platforms, as well as time constraints and staff capabilities.
