This article outlines strategies for migrating Oracle Database from on-premises vSphere environments to AWS using VMware Cloud on AWS.

• Four migration paths: Relocate (move VMs to VMware Cloud), Rehost (convert to EC2), Replatform (migrate to RDS), Refactor (change database engine)
• VMware Cloud on AWS provides high-bandwidth, low-latency connectivity to native AWS services without egress costs within same AZ
• Performance sizing requires analyzing AWR reports for DB time, vCPU usage, memory, and I/O bandwidth
• Availability considerations: RTO varies by migration path; RAC environments need RTO/RPO assessment
• Migration phases: Discovery, Design, Convert, Migration, Operation, Optimization
• Amazon RDS Custom for Oracle overcomes some unsupported features; EC2 option for knockout conditions
• AWS DMS or native Oracle Data Pump tools available for data migration
• Database Freedom program offers technical advice, migration support, and financial assistance

VMware Cloud on AWS enables seamless Oracle Database migration with multiple pathways to reduce costs and operational complexity while maintaining performance and availability.
