Case Study 12: Legacy System Automated Modernization – Data Migration
Challenge:
A top-tire bank required the migration of legacy databases into PostgreSQL, all without allowing for any physical distortion of operations on going. The challenge was to achieve zero downtime for the transformation, including consistency and improved performance with respect to the management of large financial volumes of data.
Solution:
OKRUTI provided for the phased workings of
– Custom ETL Scripts – Created advanced processes to extract, transform, and load (ETL) data seamlessly to aid in migration.
– Incremental Data Sync – Setting up real-time replication to sync the legacy and new databases until final cutover.
– Data Integrity Testing – Validating record accuracy, validation of schema, and referential integrity post- migration.
– Performance Optimization – Optimizing PostgreSQL indexing and queries to speed up transactions.
With zero downtime migration, OKRUTI made certain that the new database would have an undisturbed shift.
Results achieved:
✔ 100 percent correct data migration safeguarded financial record integrity.
✔ Minimal downtime that avoided any disruption to banking operations.
✔ Optimized database performance, which accelerated query execution.
Feedback from a customer:
“OKRUTI transacted a practically supremely smooth migration of DATA and no DATA WAS LOST.”
