Legacy and application modernization

Modernize established systems incrementally without placing ongoing operations at unnecessary risk. General Informatics covers analysis, target architecture, implementation, integration, quality assurance and production-oriented operations from one accountable partner.

Migration and operations

Introduction without unnecessary risk

Production systems are not replaced through an uncontrolled big bang. GI plans reversible steps, measurable gates and a traceable transition.

Baseline

Capture the current state, revision, data quality, performance, security status and operational dependencies.

Staging

Create an isolated environment, realistic test data, migration rehearsals and integration smoke tests.

Cutover

Prepare synchronization, freeze window, health checks, approval and an immediately usable rollback.

Long-term operation

Monitor metrics, logs, alerts, backups, restore tests, security updates and capacity limits.

Quality gates

  • Backend, frontend and integration tests
  • Security, dependency and secret checks
  • Data migration and repeatability
  • Performance and Lighthouse budgets
  • HTTP, API and critical user-flow smoke tests
  • Backup, restore and rollback evidence

Operational handover

GI provides technical documentation, environment and secret inventory, runbooks, monitoring rules, escalation routes and a maintenance plan. GI can remain involved as the technical partner for operations and further development.
