Migration Topologies

Deployment Architectures

Three flexible deployment models to match your infrastructure and geographic requirements

Architecture 01

Unidirectional Replication

The MigDB unidirectional architecture migrates data securely one-way from a legacy on-premise SQL Server to AWS RDS. An initial data load provides a baseline, and ongoing CDC maintains continuous target synchronization — with zero source downtime.

CDC Capture Phase
  • Monitors SQL Server transaction logs continuously
  • Captures INSERT, UPDATE, DELETE via LSN tracking
  • CDC Watchdog monitors lag and ensures consistency
Initial Load Phase
  • Full/Differential/Transaction log backups generated
  • Compressed, encrypted, uploaded to Amazon S3
  • MigDB Agent restores into Amazon RDS SQL Server
CDC Applier Phase
  • Reads captured changes based on LSN sequence
  • Applies transactions to keep RDS in near real-time sync
  • CloudWatch integration for live monitoring & alerting
MigDB SQL Server Unidirectional Architecture

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


MigDB SQL Server Bidirectional Architecture

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

Architecture 02

Bidirectional Replication

Secure, continuous, two-way data synchronization between on-premise and AWS. Both environments act as source and target simultaneously — enabling active-active operation, rollback capability, and coexistence validation before decommission.

Forward Replication (On-Prem → AWS)
  • CDC capture from source SQL Server transaction logs
  • Initial load via S3 backup/restore to RDS
  • Applier keeps RDS in near real-time sync
Reverse Replication (AWS → On-Prem)
  • CDC capture enabled on target RDS SQL Server
  • Changes securely transmitted back to source
  • Loop prevention via Checkpoint Table & Replication Marker

Architecture 03

Relay Deployment

The SkyliftAI Relay Architecture delivers a secure, scalable solution for cross-region migrations. By abstracting infrastructure complexity and embedding security and observability into every component, the platform enables seamless data movement across geographies.

VPC Network Design
  • Public subnet with controlled Internet Gateway routing
  • Private subnet hosts MigDB EC2 + Amazon RDS
  • NAT Gateway for secure outbound connectivity
Relay Engine Responsibilities
  • Secure connection to on-prem SQL Server via firewall
  • Extracts and processes data, manages CDC workflows
  • CloudWatch monitoring — performance, latency, alerts

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​

MigDB ComparePad

Ensure that data has been accurately transferred from source to target systems with complete integrity before go-live.

When to Use
  • Immediately after migration completion
  • Before go-live or production cutover
  • During testing and validation phases
  • After incremental or phased migrations
  • Whenever data consistency needs to be verified between systems
Advantages
  • Ensures complete data integrity and reliability
  • Reduces manual validation effort significantly
  • During testing and validation phases
  • Non-intrusive (no impact on live systems)
  • Scalable for enterprise-level databases​
  • Supports cross-platform comparisons
Usage & Integration
  • ComparePad is already integrated with SkyliftAI MigDB as part of the migration ecosystem
  • It is used after migration completion to compare source and target data
  • Helps identify and resolve discrepancies before final go-live
  • Requires separate licensing to enable and use ComparePad features
