Programme context
The Washington State Department of Ecology migrated mission-critical GIS applications, infrastructure and approximately 60 TB of environmental data from traditional infrastructure in a state data centre to Microsoft Azure, supporting more than 700 daily users and public map access.
Why this matters: This record identifies a named organisation, source and destination platforms, an affected workload and an evidence-bounded operational stage.
Migration timeline
| Date or stage | Milestone | What changed | Evidence status |
|---|---|---|---|
| Migration programme | Preparation | The department prepared its mission-critical GIS estate and environmental datasets for Azure. | Source-stated programme context |
| Core transition | Migration milestone | The source says the core migration was completed within a few days. | Source-stated duration; calendar date not stated |
| 4 May 2026 | Dated source | Microsoft published the customer account. | Dated primary evidence |
Workload migration matrix
| Workload | Predecessor | Destination | Status by 25 Jul 2026 |
|---|---|---|---|
| mission-critical GIS applications, infrastructure and approximately 60 TB of environmental datasets supporting more than 700 daily users and public map access | traditional GIS infrastructure in a Washington state data centre | Microsoft Azure with Esri configuration support | Core migration completed and operational |
Implementation and architecture
- Azure hosts the mission-critical GIS applications and infrastructure.
- Approximately 60 TB of environmental datasets support internal and public mapping workloads.
- Esri supported configuration and migration of the GIS environment.
Known unknowns and contradictions
- The exact calendar cutover date.
- The complete inventory of residual state-data-centre dependencies.
- Whether unrelated agency workloads remained in the same physical environment.
No missing fact is inferred to broaden the source-supported migration claim.
PlatformTrace analysis
The source supports the bounded GIS-platform migration and current operational state. It does not prove that every Department of Ecology workload or every state-data-centre dependency was retired.
Performance, cost, uptime and operational outcomes remain attributed source claims unless independently stated otherwise.
