D3Clarity Oracle-to-AWS Migration RDS Aurora with Postgres Compatibility

D3Clarity implements an end-to-end Oracle migration to **Amazon RDS Aurora with Postgres Compatibility **, enabling OS/database-level customization with managed automation for patching, backups, and operations. Our 4-phase methodology reduces cutover risk using AWS Database Migration Service (AWS DMS) change data capture (CDC) for near-zero downtime patterns and high-availability options. As a trusted AWS Advanced Tier Consulting Partner with the Migration and Modernization Service Delivery specialization, we plan, build, and operate your migration in your AWS account and measure success with clear, evidence-aligned KPIs.

• Discovery & Design: Current-state inventory, dependency mapping, migration factory plan, risk register, and rollback strategy
• Pilot Build (MVP): Target Aurora with Postgres Compatibility environment, networking/IAM/KMS guardrails, observability, and data validation harness
• Migration Runbook: Tooling selection (AWS DMS, Oracle Data Pump/Transportable Tablespaces (TTS), AWS Schema Conversion Tool (AWS SCT)) with step-by-step cutover plan
• Near-Zero Downtime Pattern: DMS Change Data Capture (CDC) replication, switchover rehearsal, and failback plan
• Performance & HA Configuration: Instance class/right-sizing, Multi-AZ recommendations, parameter tuning, and backup/restore tests
• Security & Compliance: KMS encryption, IAM least privilege, audit logging, and runbooks aligned to regulated environments

D3Clarity helps you maximize your results with AWS Partner Funding programs. If you are eligible, these programs can reduce or eliminate costs:

• Proof-of-Concept (POC): Funding of pilots for small-scale or initial deployments
• Migration Acceleration Program (MAP): Funding for enterprise-scale migrations
• Well-Architected Partner Program Funding: Funding for new AWS infrastructure in existing accounts Talk to our team for more information about these programs.

• Reduced Business Disruption: Many clients achieve minutes-to-low-hours planned cutovers using CDC—critical when downtime can cost up to $300K+ per hour.
• Faster Time-to-Value: Pilot-first approach validates performance and compatibility before full cutover, accelerating stakeholder confidence.
• Better Run-State Economics: Right-sizing and automation reduce toil and spend.
