Version and dependency inventory
Map Ruby, Rails, gems and services, identify unsupported components and compatibility constraints, and prioritize exposure alongside business-critical workflows.
Services for existing applications
Legacy Ruby on Rails maintenance without losing the working product
An older Rails application can still serve your business well. We assess outdated dependencies, unsupported versions and gaps in tests, then plan incremental modernization while maintaining the features your customers depend on.
Understand the inherited system first
Tests where they reduce risk
Identify important flows with weak coverage. Add regression checks around the parts being changed, including payments, jobs and integrations.
Operational knowledge
Review deployments, backups, access and recovery procedures. Document assumptions and gaps before committing to an upgrade path.
Modernize through planned, reviewable stages
Incremental upgrades
Separate Ruby and Rails changes where practical, resolve deprecations and incompatible dependencies, and validate each stage before the next release.
Safe data and storage migrations
Plan compatibility periods, backfills, validation and rollback. Preserve existing URLs, uploads and integrations while old and new implementations coexist.
Maintenance alongside delivery
Continue fixing defects and shipping needed features. Prioritize modernization against the available budget instead of allowing an open-ended rewrite to absorb it.
