Migration and refactoring

Modernize legacy platforms and monolithic systems

Migrate complete platforms to new technologies or refactor existing systems. DevSense analyzes the code, organizes the work and supervises development and testing through to a verifiable delivery.

Software modernization

From the current system to the target architecture

DevSense inspects the source system to define which behavior must be preserved and what will change in the target technology. The proposal organizes components, integrations and data transformations into verifiable deliveries.

The target can be a modernized monolith, a modular application or services, according to the architecture agreed for the project.

Modernization scope

Full migration, modularization or refactoring

Technology migration

Move a platform to new languages, frameworks or versions while retaining the behavior defined in the scope.

Monolith transformation

Reorganize the system into modules or services, with dependencies and integrations included in the migration plan.

Software refactoring

Restructure code and reduce technical debt while preserving the behavior the product needs to retain.

Migration process

What must be defined and verified in a migration

  1. 01

    Source behavior

    System functions, rules and interfaces that must keep working.

  2. 02

    Target architecture

    Technologies and structural changes included in approved scope.

  3. 03

    Integrations and data

    Dependencies, contracts and data transformations needed by each delivery.

  4. 04

    Functional equivalence

    Tests of required behavior in the new implementation, alongside code review.

  5. 05

    Incremental acceptance

    Sandbox and evidence to assess changes and plan their release.

Detected defects return to development and go through review and testing again.

Migration validation

Verify behavior on the new technology

Business rules, interfaces and integrations that must be preserved become acceptance criteria. DevSense reviews and tests the new implementation against those outcomes; changing technology does not authorize a reduction in scope.

Schema changes and data transformations are included in the scope and tests when required by the migration. Production rollout follows the policies agreed for the project.

  • Web, API, database and CLI tests according to product interfaces.
  • Authentication and permissions included in validation scenarios.
  • Evidence linked to the version reviewed and prepared for delivery.

Modernization questions

Can DevSense migrate an entire platform?

DevSense can undertake platform-wide migrations through scoped requirements and verifiable milestones. Before execution, the target architecture, preserved behavior and validation of in-scope integrations and data are defined. Your team approves the plan and reviews each delivery.

Does everything need to migrate at once?

The scope can be organized by component, feature or milestone. This allows successive deliveries to be reviewed and integrations between migrated components and the remaining system to be checked.

Does refactoring require a change of technology?

No. You can reorganize code, separate responsibilities and address technical debt on the current stack. Changes to language, framework or architecture are included when they are part of the project objectives.
