What Makes MigDB Different

Proprietary in-house solution with built-in optimization and advanced CDC — purpose-built for Oracle at enterprise scale

Automated Deployment

Fully automated, one-click software deployment with complete solution packaging — no manual setup complexity, error-free installation.

Agentless & Remote Architecture

MigDB agentic process beats network latency. Remote deployment accesses on-premise Oracle databases without installing anything on-site.

Enterprise Security

AES 128/192/256-bit encryption of data at rest and in transit. Secured wallet for database connectivity. SSL/TLS for all cross-region transfers.

50% Faster Initial Load

Optimized initial load with data partitioning and simulated parallelism — enabling terabyte-scale LOB data to complete within hours, not days.

Robust CDC

Highly accurate and stable Change Data Capture process. Captures real-time inserts, updates, and deletes with no impact on source database performance.

Intuitive GUI

World-class, user-friendly interface enabling mid-level engineers to manage complex Oracle migrations without deep CDC expertise.

Migration Topologies

Deployment Architectures

Three flexible deployment models engineered for Oracle — from same-region migrations to global cross-continent workloads

Architecture 01

Unidirectional Replication

MigDB migrates Oracle data securely one-way from a legacy on-premise environment to AWS RDS. An initial bulk data load creates the baseline, then ongoing CDC maintains continuous synchronization — with zero source downtime throughout.

Phase 1 — CDC Capture
  • MigDB Agent initiates CDC from source Oracle
  • Tracks real-time inserts, updates, deletes into secure CDC files
  • CDC Watchdog monitors capture health, lag, and consistency
Phase 2 — Initial Bulk Load
  • MigDB extracts data using inbuilt bulk load functionality
  • Splits into multiple encrypted dump file chunks, transferred securely
  • MigDB Agent on target decrypts and ingests into Amazon RDS Oracle
Phase 3 — CDC Apply & Monitoring
  • Applier reads CDC files and applies changes to target in source order
  • Ensures transactional consistency throughout migration window
  • MigDB Console + Amazon CloudWatch for real-time observability
MigDB Oracle Unidirectional Architecture

Unidirectional — On-Premise Oracle → AWS RDS Oracle (Same Region)


MigDB Oracle Bidirectional Architecture

Bidirectional — On-Premise Oracle ⇄ AWS RDS Oracle (Same Region)

Architecture 02

Bidirectional Replication

Secure, continuous two-way data synchronization — both on-premise and AWS environments function as source and destination simultaneously. Enables active-active operation, rollback confidence, and warranty-period source continuity before decommission.

Forward Replication (On-Prem → AWS)
  • CDC capture from source Oracle, initial load via encrypted dumps
  • Applier applies changes in source transaction order to RDS
  • Near real-time synchronization maintained throughout
Reverse Replication (AWS → On-Prem)
  • MigDB Agent also captures changes on target RDS Oracle
  • CDC files securely transmitted back to source environment
  • Enables active-active, rollback, and warranty-period support

Architecture 03

Relay Deployment

Purpose-built for cross-region and cross-continent Oracle migrations. The SkyliftAI Relay Architecture reduces replication latency by placing the MigDB relay near the target RDS instance — proven in a large-scale intercontinental migration spanning over 6,000 miles.

How the Relay Works
  • Source MigDB Agent deployed at customer on-premise data center
  • CDC files sent securely to the target-side remote MigDB deployment
  • Relay Engine on EC2 (private subnet) applies data to RDS Oracle
Security & Network Design
  • AES 128/192/256-bit encryption; source encrypted before transit
  • VPC with public/private subnets, NAT Gateway, security groups
  • CloudWatch monitoring for full cross-region visibility
MigDB Oracle Relay Architecture

Relay Deployment — Cross-Region / Cross-Continent (e.g. Amsterdam → Singapore)

Why Enterprises Switched from AWS DMS to MigDB

AWS DMS was the initial tool — MigDB replaced it after critical challenges emerged in the existing environment.

Challenge 01
Cross-Region Latency

DMS: Initial deployment in AWS Ireland caused high replication latency across regions.

MigDB: Architecture enhanced with SkyliftAI Agents in IBM Amsterdam and AWS Singapore — achieving near-zero CDC latency.

Challenge 02
Large LOB Column Performance

DMS: Tables with Basicfile LOB columns (single partition) took days for initial load.

MigDB: SkyliftAI Agent partitioned data by table key columns, simulating parallelism — completing terabyte-scale LOB loads within hours.

Challenge 03
Encryption & Security Compliance

DMS:Could not satisfy enterprise infosec requirements for additional encryption over the AWS VPN tunnel.

MigDB:SkyliftAI Agent encrypts data at the source (IBM Cloud) before transit — approved by enterprise infosec teams..

Database Assessment

The first and most critical step — analyze your source environment and provide a detailed report for a smooth migration.

When to Use
  • Before starting any migration
  • During migration planning and strategy phase
  • To evaluate compatibility with target platforms (e.g., AWS RDS)
  • To estimate infrastructure sizing and cost​
  • To identify risks, blockers, and required changes
Key Features
  • Analyzes database size, schemas, and object distribution
  • Provides feature compatibility analysis (Partitioning, Encryption, etc.)
  • dentifies migration blockers and required actions Captures performance metrics (CPU, IOPS, Memory Usage)
  • Generates detailed assessment reports for planning
  • Maintains assessment job history for tracking and reuse
Advantages
  • Helps in choosing the right target instance and configuration
  • Reduces migration risks by identifying issues early
  • Provides clear visibility into database complexity
  • Enables cost optimization with accurate sizings
  • Improves migration success rate with data-driven insights
Usage & Recommendation
  • Database Assessment is integrated with SkyliftAI MigDB as the initial phase of migration
  • Once the assessment is completed, it suggests the most suitable target instance (e.g., AWS RDS instance types like db.t3.large, db.m5.large)
Recommendations are based on:​
  • CPU usage (peak & average)​
  • Memory requirements​
  • IOPS and storage patterns​
  • Database size and growth factor
  • The generated report should be referred to finalize infrastructure decisions
Report Access & Download
  • Assessment reports are downloadable at any time
  • All assessments are stored under Assessment Jobs History
  • Users can revisit, review, and download any past assessment report whenever required
  • This ensures easy access for audits, planning, and future reference
Final Outcome
  • Using the assessment report,teams can confidently select the right infrastructure, avoid over/under provisioning, and ensure a smooth and optimized migration process​
