Overview
An enterprise IT team managed two hundred VMs across three data centers nearing end of lease. Manual lift-and-shift attempts had stalled after a failed pilot that caused weekend downtime for an internal ERP system.
Mobintix built a migration control plane that inventories servers, maps dependencies from network flows and configuration agents, generates Terraform modules, and orchestrates waves with rollback checkpoints. Containerized workloads deploy to EKS; stateful systems use managed RDS with rehearsed cutover runbooks.
Executives view migration burndown charts; engineers approve each wave through gated pipelines.
Challenge
Dependency maps were outdated. Teams feared data loss during database cutovers. Compliance required encryption in transit and at rest with customer-managed keys before production traffic could move.
Approach
Lightweight agents and network discovery rebuilt dependency graphs validated by application owners. Database migration used dual-write windows with checksum verification before DNS flips. KMS-backed encryption applied by default in generated Terraform. Each wave includes automated smoke tests and one-click rollback to on-prem snapshots if error budgets breach.
Outcomes
- Migration waves completed fifty percent faster than the prior manual program.
- Post-migration infrastructure costs decreased through right-sizing recommendations applied automatically.
- No production wave exceeded the agreed downtime window after wave three.
- The IT team retained Terraform modules and runbooks to continue internal waves after Mobintix handoff.
Lessons learned
Never migrate without owner-signed dependency graphs — assumptions cause outages. Rehearse database cutovers in staging with production-scale data. Automate rollback before automating forward migration.
Celebrate small waves publicly — migration programs lose political support when only engineering sees progress burndown charts.
