A major concern that businesses have is if the data was migrated
completely and accurately. If any data is left behind, it may result
in potential loss of revenues. It may also break some regulatory
compliance such as Sarbanes-Oxley Act (SOX) of 2002 and Health
Insurance Portability and Accountability Act (HIPAA) of 1996. These
acts require that an audit trail be maintained (and accurately
migrated) for certain types of data such as employee work history
with the company.
To measure the accuracy of data migration, it is important to
define business rules for post-migration quality checks. For
example, you may wish to compare the outstanding balance in the new
system with the outstanding balance in the legacy system. xFusion Studio
makes it easier to define such business rules where a comparison has
to be made between the new system and the legacy system.
