Zero-downtime Azure migration for a US logistics company
The Challenge
A 120-person US logistics company was running critical dispatch and operations software on ageing on-premises servers approaching end of vendor support. Hardware refresh costs were significant, redundancy was poor, and a single server failure would halt operations. The business needed cloud migration without impacting daily dispatch runs — any weekday outage would have direct financial and client consequences. Previous internal attempts to plan the migration had stalled over risk concerns.
Our Approach
BPro IT ran a four-week discovery and architecture phase to map all workloads, assess cloud readiness, and define migration sequencing. We designed an Azure landing zone with appropriate network segmentation, backup policies, and disaster recovery configuration. The migration was executed across three scheduled weekends — Friday evening to Sunday evening — with each weekend covering a defined workload scope, documented rollback criteria, and a go/no-go checkpoint before each phase began. On-call support was available throughout each window.
The Outcome
All workloads migrated to Azure with zero unplanned downtime across the three weekends. Weekday operations ran without interruption throughout the project. Full runbooks, architecture documentation, and Azure configuration records were handed over at project close. The client now operates on infrastructure with documented RTO and RPO targets and automated backup testing.
- Zero unplanned downtime across the entire migration
- All workloads live in Azure within 3 scheduled weekends
- Full runbooks and architecture docs delivered at handover
- Automated backup and DR configuration in place
- Weekday operations unaffected throughout
