Which migration strategy involves moving an entire dataset in one operation?

1. Incremental Migration

2. Block Migration

3. Big Bang Migration

4. Phased Migration

The correct answer is: Big Bang Migration

The migration strategy that involves moving an entire dataset in one operation is known as Big Bang Migration. This approach entails transferring all data and components from the source system to the target system at once, usually within a defined short timeframe. This method is typically chosen when the entire dataset needs to be synchronized simultaneously, making it necessary to ensure that all parts function cohesively after the migration. The Big Bang Migration is often favored due to its straightforward approach, which can simplify the process and reduce the time to completion. However, it does require careful planning and risk management to address potential issues that might arise during the transition, as any problems encountered can affect the entire dataset being migrated at once. In contrast, other migration strategies like incremental, block, and phased migrations involve different approaches that do not consolidate the entire dataset in one go, which makes them distinct from the Big Bang method.
