NewDay rearchitects Azure Cosmos DB containers and migrates under full production load

Microsoft's dated customer story says NewDay rearchitected Azure Cosmos DB containers and used Azure Databricks to migrate a container while at full production load with zero downtime.

Organisation
NewDay, United Kingdom
Predecessor
the pre-rearchitecture Azure Cosmos DB container design within NewDay's existing cloud-native platform
Destination
rearchitected Azure Cosmos DB containers migrated with Azure Databricks while the source-described platform remained under full production load
Workload
Azure Cosmos DB
Stage
operational
Evidence boundary: The dated Microsoft source proves the bounded Cosmos DB container rearchitecture and migration under production load. Azure Cosmos DB was already part of NewDay's platform, so this is not represented as a vendor-to-vendor database replacement; the source does not prove retirement of every prior dependency or disclose a private cutover day.
