Microsoft has released an early access version of Database Hub.

According to Techzine on March 19, Database Hub is an integrated hub that lets users manage databases across edge, platform-as-a-service (PaaS) and Fabric from a single screen. It supports Azure SQL, Azure Cosmos DB, Azure Database for PostgreSQL, Azure Arc-enabled SQL Server and Azure Database for MySQL.

Microsoft previously introduced Fabric IQ as an intelligent layer that turns data into autonomous decision-making. Database Hub includes native visibility, delegated governance and Copilot insights, enabling database teams to manage the entire environment in one place.

Microsoft added a preview migration assistant feature to SQL databases in Fabric. It supports users in assessing migration readiness, identifying compatibility issues and carrying out schema migration from SQL Server to Fabric. Microsoft also introduced support for all Azure SQL data collations, per-database compute limit settings and backup retention period adjustments from 1 to 35 days.

For Cosmos DB, a feature supporting private networks when mirroring to Fabric has been officially released. It enables secure mirroring of data to OneLake from Cosmos DB accounts protected by private endpoints or VNETs, without changing network security settings.

Microsoft is also releasing an open-source Azure Cosmos DB Agent Kit. It is a collection of agent technologies that add Cosmos DB data modeling and partitioning specialist capabilities to AI coding assistants such as GitHub Copilot CLI and Claude Code.

Microsoft said it acquired Osmos in January 2026 to strengthen AI-based data ingestion capabilities within Fabric.
