It is necessary to remark that testing a data migration must start properly in advance of the actual data being migrated.
It is very typical that one of the essential commodities that a business control, owns, or controls is its data and hence any data migration must be considered high risk and should be implemented to significant verification and validation efforts.
A business may decide to reduce the risk level against the data migration, but it is always reasonable to start off with data migration as a high-priority task to make sure it is successful.
Some important trends and solution patterns that must be analysed while creating efficient data migration testingare agile, big data, DevOps, cloud, service virtualization with TDM, accelerators and domain-specific solutions, and automation to reduce time-to-market and increase efficiency.
This document gives some of the keys consideration points to a test team so that effective test planning and strategizing can be achieved for an ETL project.
