- 12. What are the risks? Assessment and Feasibility
- 13. What applications to start with? Good to Start with Avoid • Developed using open standards • Open standard connections • Not much dependent on server side code – stored procedures etc • Vendor already supports Postgres or EDB Postgres • No RAC scalability requirement • No need of flashback • Uses proprietary connection method e.g. tnsnames • Multiple DBlink dependencies or dependents • Has dependencies on other applications/databases

- 15. Migration Assessment using Migration Portal • How easy will it be to perform the migration? • What are the risks? • Will all my server side code (Stored procedures) work fine? • Is my application compatible? • How much testing effort will be needed?
- 19. Customer Use Cases Challenges and success stories
- 20. Telecom case study : Schema migration • Application Platform and drivers : Java (JDBC) • Reason for Migration : 1. Operational cost reduction 2. Oracle License Cost • Challenges : 1. Interval Partitions 2. Views 3. DB links 85% Compatibility with EDB Postgres advance Server Oracle Compatibility features of EDB Postgres Advance Server 60% schema Compatible with PostgreSQL
- 21. Government Use Case : Schema Migration • Application Platform and drivers : application on Java (JDBC) • Reason for Migration : 1. Oracle License Cost 2. Microservices • Challenges : 1. Oracle RAC 2. Schema with more than 700 objects and Approx. 3TB size schema for migration 3. Oracle security features 4. Oracle unlogged tables
