Choosing an older SQL Server target is a technical and business decision. The right target balances client infrastructure, feature support, licensing, and long-term maintainability.
Match the client environment
Start with the destination instance and operating constraints. If a client is validated on SQL Server 2014, use that engine as the target instead of selecting an even older version without a clear requirement.
Compare features, licensing, and cost
Review collations, T-SQL features, ERP requirements, cloud capacity, and edition licensing. A newer supported target may reduce conversion work, while a legacy target may be mandatory for a validated deployment.
Run a read-only decision audit
Before committing, scan the source for blocking features and unsupported definitions. Use the findings to approve the target version and document exceptions before conversion begins.
Choose the right target with evidence
Check compatibility before committing your team to a target SQL Server version.
