.NET & Java Technology Upgrades

Enterprise Runtime Upgrades for .NET & Java Estates

SanguineIT upgrades legacy .NET and Java applications to supported runtimes — .NET Framework to .NET 8, JDK 8/11 to current LTS releases, Spring Boot modernization, and application server migrations — so enterprises stay secure, supported, and eligible for cloud deployment.

Our upgrade programs include dependency analysis, automated test baseline creation, incremental migration sprints, and parallel run validation — reducing the risk of big-bang cutovers that stall IT roadmaps for years.

See dedicated .NET migration and legacy migration services for broader modernization scope.

Technology upgrade capabilities

• .NET Framework to .NET 8 — WebForms, MVC, WCF, and Web API upgrade paths.
• JDK & Spring upgrades — Java version migrations and Spring Boot dependency updates.
• App server migration — WebLogic, WebSphere to Tomcat, Spring Boot, or cloud containers.
• Library & dependency refresh — CVE remediation through supported package versions.
• Automated test baselines — Regression suites before and after upgrade phases.
• Cloud readiness — Containerization and Azure/AWS deployment after runtime upgrade.

Upgrades sequenced for production safety

Unsupported runtimes are a security and hiring liability. SanguineIT sequences .NET and Java upgrades in phases your operations team can absorb — with rollback points, documented API changes, and stakeholder sign-off gates at each milestone.
