A multi-phase migration of hundreds of workloads, led from roadmap through final cutover. On-prem retired on schedule. Zero unplanned downtime.
A national retailer needed to move hundreds of workloads out of its on-prem environment against a fixed retirement date. The estate had grown over years: interdependent applications, shared infrastructure, and an IT organization whose day jobs didn't stop for the migration.
The risk wasn't any single workload. It was sequencing: move things in the wrong order, or without the people who run them ready, and a retail business takes customer-facing downtime.
Full workload inventory and dependency mapping, then wave sequencing driven by business risk. The order of operations was agreed with stakeholders before anything moved.
Account structure, identity, networking, and guardrails established before the first workload migrated, so every wave landed in an environment that was already governed.
Migrate in phases, validate against acceptance criteria, then cut over with rollback plans in place. Each wave informed the next.
Over 300 IT stakeholders trained on cloud adoption practices, so operations scaled with the migration instead of bottlenecking on the migration team.
Hundreds of workloads migrated. The on-prem environment retired on schedule. Zero unplanned downtime across the program. And an IT organization that came out the other side able to operate the new environment, because enablement was part of the engagement, not an afterthought.
