Product Overview

MigDB Product Introduction

Introducing Skylift AI's MigDB: Revolutionize Your Database Migrations. Experience the future of enterprise data management with MigDB, the AI-powered solution ensuring zero data loss and seamless transitions from legacy DB2 for i and DB2 for z/OS systems to modern cloud platforms.

MigDB Product Introduction

What Makes MigDB Different

Proprietary in-house solution with built-in optimization and advanced CDC — purpose-built for DB2 for i and DB2 for z/OS 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 DB2 for i and DB2 for z/OS systems without installing anything on-site.

Enterprise Security

AES 128/192/256-bit encryption of data at rest and in transit. Secured credential store 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 table and LOB data to complete within hours, not days.

Robust CDC

Highly accurate and stable Change Data Capture process built on DB2 journal receivers (DB2 for i) and recovery log reads (DB2 for z/OS). 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 DB2 migrations without deep CDC expertise.

Migration Topologies

Deployment Architectures

Three flexible deployment models engineered for DB2 — from same-region migrations to global cross-continent workloads

Architecture 01

Unidirectional Replication

MigDB migrates DB2 data securely one-way from a legacy IBM i or z/OS environment to AWS (DB2 LUW on EC2, or DB2 z/OS via DB2 Connect). 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 journal receivers (Db2 for i) or the recovery log (Db2 for z/OS)
  • 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 the target DB2 environment
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 DB2 Unidirectional Architecture

Unidirectional — On-Premise DB2 (i / z/OS) → AWS (Same Region)

MigDB DB2 Bidirectional Architecture

Bidirectional — On-Premise DB2 (i / z/OS) ⇄ AWS (Same Region)

Architecture 02

Bidirectional Replication

Secure, continuous two-way data synchronization — both on-premise (IBM i / z/OS) 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 journal receivers / recovery log, initial load via encrypted dumps
  • Applier applies changes in source transaction order to the target DB2 environment
  • Near real-time synchronization maintained throughout
Reverse Replication (AWS → On-Prem)
  • MigDB Agent also captures changes on the target DB2 environment
  • CDC files securely transmitted back to the source environment
  • Enables active-active, rollback, and warranty-period support
Architecture 03

Relay Deployment

Purpose-built for cross-region and cross-continent DB2 migrations from IBM i and mainframe environments. The SkyliftAI Relay Architecture reduces replication latency by placing the MigDB relay near the target AWS environment — proven in a large-scale intercontinental migration spanning over 6,000 miles.

How the Relay Works
  • Source MigDB Agent deployed at the customer's IBM i or z/OS data center
  • CDC files sent securely to the target-side remote MigDB deployment
  • Relay Engine on EC2 (private subnet) applies data to the target DB2 environment
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 DB2 Relay Architecture

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

Database Assessment

The first and most critical step — analyze your source DB2 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)
  • To estimate infrastructure sizing and cost​
  • To identify risks, blockers, and required changes
Key Features
  • Analyzes database size, schemas, libraries, and object distribution
  • Provides feature compatibility analysis (journaling, partitioning, encryption, etc.)
  • Identifies 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 sizing (e.g., AWS EC2 instance types like m5.xlarge, r5.2xlarge for DB2 LUW)
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​
