Case Study: Leading Online Education Service Provider achieves zero-downtime Postgres upgrade and performance gains with EnterpriseDB

Leading Online Education Platform Accomplishes a Vital Upgrade with Support from EDB

Headquartered in Amsterdam, this leading online education platform provides digital learning assets and high-stakes exams for medical and nursing students worldwide, so its Postgres databases must be highly available. When Postgres 9.6.13 neared end-of-life, the company prioritized an upgrade to avoid unsupported systems and potential downtime, beginning with lower environments for testing; during preparation they hit significant roadblocks—most notably an incompatibility with their Linux AMI 1.0—that threatened the timeline and reliability of the upgrade.

EDB’s Remote DBA and Professional Services led a careful PoC, identified the OS limitation, and helped the team upgrade to AMI 2.0 and migrate straight to Postgres 14.1 with BARMAN-backed backup/recovery. Coordinating international teams, they executed overnight upgrades with near-zero downtime, immediate performance gains, continued 24/7 support, and no student-impacting incidents—ensuring the platform’s high availability and supported Postgres environments.
