  • Necessary migration to a new infrastructure put the company at risk ​
  • Possible negative consequences included: loss of vital information, financial losses caused by unavailability of systems, security non-compliance


  • Systems remain active during migration, there is no downtime​
  • There are no application errors caused by incompatibility with the new environment, and data consistency is confirmed after migration ​
  • The migration does not disrupt business at any time throughout the process​


Implementing real-time data replication can solve current business continuity and data access problems, and be a starting point in a journey to an entirely data-driven enterprise.
