Why leave Oracle database?
Oracle’s high licensing costs
• Many features now commoditized
• Painful contract terms
70% of new apps on open source
DBs
• Take control
• Increase innovation
• Reduce lock-in risks
Cloud/containers increasingly important
• Cloud provides new alternatives
• Often coupled with open source

What obstacles exist?
Migrations are hard Oracle skills
Troublesome contracts Apps designed for
Oracle
• Much assessment and effort required
• Across schema, data, and application
• Businesses have invested Oracle
training
• Concern of losing those skills/expertise
• Oracle licenses are complicated
• And audits are disruptive
• Oracle-specifics ingrained in the app
• Difficult to migrate one without the other

The considerations of a migration
• Objects and code
• Mapping data types
• Handling syntax differences
• Raising incompatibilities
Schemas
• Methodology: Bulk, ongoing, fallback
• Tools: ETL, validation
Data
• Hosting environment
• Deployment type
• DBMS optimization
• Proprietary utilization

• Code
• Languages
• Connectors
• Syntax
Application
• Performance
• Optimization
