4. Create CDS User (Application user) for testing
5. OGG Configuration on Source Oracle 10gR2
a) Set the environment
b) Login to Database
c) Configure Manager
d) Create Extract Group
e) Create Pump Group
f) Add supplemental logging
6. OGG Configuration on Target Oracle 11gR2
a) Set the environment
b) Login to Database
c) Configure Manager

8. On Source Start Manager, Extract and Pump
9. On Target start the Manager only
10. Export data from source Oracle 10gR2
11. Transfer the dumpfile to 11g DATA_PUMP_DIR
12. Generate data on source Oracle 10gR2 (After Export)
13. Import Data and Start Replicat on Target 11gR2
14. Test and Verify the Results
a1) Execute INSERT again on the Source Oracle Database 10gR2
a2) Verify Insert Changes on Target Oracle Database 11gR2
b1) Execute update on the Source Oracle Database 10gR2
b2) Verify Update Changes on Target Oracle Database 11gR2
c1) Execute Delete on the Source Oracle Database 10gR2
c2) Verify Delete Changes on Target Oracle Database 11gR2
