Migration Execution

• Execute middleware migrations from Heritage → NGDC using approved approaches
• Monitor migration jobs, remediate failures, and validate configuration/object synchronization
• Ensure service continuity, message/data integrity, and minimal downtime

Cutover & Validation

• Support production and pre‑production cutover activities and HA/DR failover drills
• Validate application connectivity and obtain functional sign‑off from stakeholders
• Update CMDB, compliance, and operational documentation
• Deliver build scripts, migration reports, and execution metrics
• Close Jira stories and Service Now change/incidents
• Support legacy middleware decommissioning and handover to steady‑state teams
