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

Assessment and Effort estimation

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?
