Gremlin API (Azure Cosmos DB) to Azure Managed Instance for Apache Cassandra using JanusGraph - 8 Weeks Implementation

MAQ Software delivers a secure, end‑to‑end migration of Azure Cosmos DB for Apache Gremlin graph data to Azure Managed Instance for Apache Cassandra using JanusGraph, ensuring preserved vertices, edges, and relationships—optimized for performance, reliability, and reduced migration risk.

Objective

Migrate Gremlin graph workloads from Azure Cosmos DB Gremlin API to Azure Managed Instance for Apache Cassandra, ensuring data integrity, validated outcomes, and minimal disruption.

Target Audience

• Database Administrators (DBAs)
• Cloud & Infrastructure Architects
• Application Owners
• IT Operations & Platform Teams
• Enterprise Migration & Modernization Teams

Agenda & Deliverables

Week 1–2: Migration Strategy & Readiness Assessment

• Analyze current Gremlin graph environment
• Identify graph‑level and database‑level migration scope
• Define success criteria, downtime expectations, and migration goals

Week 3: Environment & Connectivity Validation

• Deploy migration environment with ARM templates
• Provision Azure VM and install JanusGraph
• Validate source Gremlin connectivity and Cassandra MI target
• Perform automated SSL, credential, and network diagnostics

Week 4: Migration Planning & Configuration

• Select migration mode and execution strategy
• Configure JanusGraph for source and target environments
• Set up parallel execution and automated batching for vertices & edges

Week 5–6: Migration Execution & Monitoring

• Execute migration using JanusGraph
• Real‑time monitoring of progress, performance, and batch operations
• Capture migration logs, history, and error handling

Week 7–8: Pre‑ & Post‑Migration Validation & Optimization

• Validate schema compatibility
• Verify data mappings for vertex/edge properties
• Perform vertex/edge count integrity checks
• Review performance metrics and optimize post‑migration

Deliverables

• Fully migrated graph databases and graph subsets
• End‑to‑end migration strategy (graph‑level + database‑level)
• Migration history, logs, and performance reports
• Pre‑ and post‑migration functional validation

Benefits

• Seamless migration with preserved vertices, edges & relationships
• Built‑in validation, troubleshooting, and dependency checks
