Preparing for Microsoft SQL Server 2025: A Strategic Outlook for Tech Decision-Makers

The imminent arrival of Microsoft SQL Server 2025 is set to be a pivotal moment for data management professionals and technology leaders. With Release Candidate Zero (RC0) having been made public in August, industry anticipation is high for the formal announcement expected at the upcoming PASS and Ignite conferences in November, aligning with Microsoft’s traditional release cadence.

This new version is poised to bring significant advancements, though, as is often the case with major platform releases, not all promised features – including the touted AI capabilities – may be fully production-ready initially. However, tech decision-makers must turn their attention to the substantial security enhancements that SQL Server 2025 will introduce.

Navigating Security and Adoption Headwinds

A major, security-enhancing change in SQL Server 2025 is the likely assumption that encrypted connections are automatically enabled by default. While this significantly hardens the platform, it represents a potentially breaking change that could impact existing infrastructure, including configured linked servers and SQL Server Replication. Organisations must factor this configuration shift into their upgrade and testing strategies.

Beyond these challenging, yet critical, security mandates, the release offers pragmatic improvements, such as making the Developer Edition available in both Standard and Enterprise compatible versions.

The timing of this release is especially pertinent. With SQL Server 2016 exiting extended support next year, many organisations face an urgent end-of-life decision. While Xynomix’s data shows a strong drive to remain current, with nearly 30% of its customers’ SQL instances already on 2022, approximately 15% of customer systems are on the older 2016 version. This substantial segment will be driven to upgrade, making the new version a critical consideration.

Industry experts anticipate a phased rollout, with development versions and greenfield deployments appearing shortly after the official announcement. However, widespread adoption is expected to gain momentum starting in Spring next year, once the platform has had approximately six months in the general release environment and software vendors have had time to certify their products.

The Convergence of Cloud, Security and Compliance

The growing intensity of database security concerns has escalated the need for businesses to meet increasingly stringent audit and legal security requirements. This trend strongly favours a migration to more secure versions of the SQL Server platform.

This security imperative runs parallel to the steady growth of cloud-based solutions, particularly Azure, though deployments in AWS and Google Cloud are also prominent. Microsoft’s strategy of developing new features within its Platform as a Service (PaaS) offerings – specifically Azure SQL Database and Managed Instance – before cross-pollinating them to the on-premises version means that many of SQL 2025’s key innovations have already been field-tested in the cloud environment. Businesses utilising these Azure PaaS offerings will already have seen precursors to the features deployed in the new on-premises SQL Server 2025.

As a leading UK-based database services provider, Xynomix will be closely following the development and deployment lifecycle of Microsoft SQL Server 2025. The firm is committed to assisting organisations in strategically planning and executing the secure transition to this next-generation database platform. Technical decision-makers are encouraged to engage with the specialists at Xynomix to ensure a smooth, compliant, and security-focused migration.
