2. Agenda
• Pain-points and what choices you have
• Why migrate to EDB Postgres?
• Assessment and Migration Strategy
• Migration and next steps
• How we can help you

3. The BIG Pain-Point

4. What choice do I have?
4
PostgreSQL

5. What EDB Postgres offers

6. Process Architecture – Much like Oracle!
• Reliable without
compromising on
performance
• Scalable
• Ensures
performance (data
read-write caching)
• Conforms with ACID
transaction model

7. • Run applications written for Oracle
virtually unchanged
• No need to re-train Oracle DBAs and
developers
• Support for PL/SQL language and OCI
interoperability
• Replication for easy sharing of data
• Dramatic Cost Savings
• No Vendor Lock-in
Oracle Compatibility

13. Step-2: What are the risks?
Assessment and Feasibility

14. Good to Start with
• 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
Don’t choose
• Uses proprietary connection
method e.g. tnsnames
• Heavily dependent on stored
procedure
• Multiple dblink dependencies or
dependents
• Has dependencies on other
applications/databases
What applications to start with?

15. • 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?
