Illustrative Example
The zero-downtime 500GB migration that took 3 months to plan
A DBA with Conscientiousness at 90 and Emotional Stability at 82 was tasked with migrating the main 500GB database from PostgreSQL 11 to PostgreSQL 15 with zero downtime. His high Conscientiousness led him to build a detailed rollback plan before presenting the migration plan. His four dry runs in staging revealed three edge cases that would have caused data loss. The final migration took a 47-minute maintenance window, with no data loss and a rollback plan ready the entire time.
