Migration –RDS Planning •Which Oracle edition should I choose? •Enterprise Edition, Standard Edition or SE1 (BYOL) •Optimize cost with Oracle SE1 with license included •Review RDS Oracle documentation •User Guide http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Welcome.html •Common tasks DBA tasks for the Oracle http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/Appendix.Oracle.CommonDBATasks.html
Instance Selection •RDS offers a wide range of instance classes •Instance types differ on CPU, RAM, network performance, EBS Optimized •Base selection on •Performance •Cost (will differ based on type and region) •Region (not all instance types available in all regions) •Elastically scale instance size up/down

Recommendations •Take advantage of Data Pump options •Choose the largest RDS instance. Once the import is done change the RDS instance to your preferred type •For the import, only choose single AZ. Once the import is done you can enable multi-AZ •P-IOPS will improve import performance
