Ruby on Rails Upgrade

Upgrade Ruby on Rails without freezing your product roadmap.

Senior Ruby on Rails engineers who own the upgrade from assessment to production. Your team stays on the roadmap. We handle the dependencies, the deprecations, and the rollout.

The problem

Tech debt is blocking what's next.

Ruby on Rails upgrades get harder the longer you wait. Most teams know they need to upgrade. The problem is finding the time, confidence, and senior judgment to do it without slowing the business down.

Unsupported Rails versions

Security and compatibility risk keeps growing with every month on an outdated version.

Fragile dependencies

Gems, packages, and integrations become harder to untangle the longer they sit.

Low test confidence

Every change feels risky when coverage is thin or the test suite is slow and unreliable.

Product teams stuck in maintenance

Your best engineers get pulled away from roadmap work to fight fires that never fully go out.

This isn't just cleanup. It's the foundation for what your product does next, including the AI and LLM integrations your competitors are already building.

Who this is for

Teams running critical Rails apps that can't afford a risky upgrade.

You've got a real product, real users, and real business pressure. The application works, but the stack is starting to slow everything down.

Behind on Rails or Ruby versions

You're on Rails 7, 6, 5, 4, or older and know the next upgrade won't be simple.

Product roadmap pressure

Your internal team needs to keep shipping value, not spend a quarter buried in upgrade work.

Complex codebase

Your app has custom business logic, integrations, background jobs, payments, APIs, or legacy patterns that make a simple upgrade unrealistic.

Need senior judgment

You don't need more hands. You need people who know how to sequence the work, reduce risk, and leave the codebase better than they found it.

What we do

Rails upgrades handled by senior engineers.

We embed with your team, understand your application, and drive the upgrade forward through a structured, battle-tested process.

Ruby and Rails upgrades

We upgrade across Ruby and Rails versions with a practical plan covering dependencies, deprecations, tests, boot strategy, and production rollout.

Legacy Rails modernization

We clean up the areas that slow future development: outdated patterns, fragile services, slow tests, and hard-to-change architecture.

API-driven development

We modernize Rails applications powering internal tools, customer-facing products, mobile apps, AI workflows, and third-party integrations.

Custom web application development

When modernization reveals the need for new capabilities, we extend the app with production-ready features and integrations.

MVP and rapid prototyping

For teams spinning up a new product or internal platform, we build fast on Rails with a senior product and engineering team.

Team augmentation

We work alongside your team as senior Rails capacity, helping you move faster while transferring knowledge as we go.

Our process

A safer path from outdated to upgraded.

We don't disappear into a codebase and come back months later with surprises. We work in visible stages, keep your team involved, and make progress without disrupting the roadmap.

1
Phase 1

Assess

We review your Rails and Ruby versions, gem dependencies, test suite, CI/CD, infrastructure, and risk areas.

Output: Upgrade plan, risk map, sequencing, and recommended path.

2
Phase 2

Stabilize

We identify the blockers that will make the upgrade painful: failing tests, missing coverage, dependency conflicts, deprecated APIs, and fragile deployment paths.

Output: Cleaner baseline, prioritized fixes, and confidence to move forward.

3
Phase 3

Upgrade

We move version by version using the right strategy for your codebase: dual booting, dependency isolation, deprecation cleanup, test hardening, and incremental pull requests.

Output: Upgraded Rails and Ruby versions with visible progress throughout.

4
Phase 4

Launch

We support production rollout, monitor issues, fix post-upgrade problems, and help your team adopt the new version confidently.

Output: Upgraded application, documentation, handoff, and post-launch support.

Capabilities

The hard parts your team doesn't have time to untangle.

Version strategy

Which version to target, whether to upgrade incrementally, and how to sequence Rails, Ruby, gems, and infrastructure changes.

Dependency cleanup

Gems, packages, compatibility issues, deprecated libraries, and upgrade blockers resolved systematically.

Test coverage and CI

Improving the test baseline so the team can move with confidence, not guesswork or crossed fingers.

Dual boot and incremental rollout

When needed, we help your team run old and new Rails versions side by side to reduce deployment risk.

Code modernization

We clean up patterns that slow development, create bugs, or make future upgrades harder.

Production readiness

Release planning, monitoring, issue resolution, and support after the upgrade is live.

The honest case

Why not handle it internally?

Your engineers know the product. That doesn't mean they should lose months to an upgrade that pulls them away from customer-facing work.

A Rails upgrade is full of hidden traps: dependency chains, version-specific behavior changes, test gaps, deployment risk, and old decisions nobody remembers making.

We bring senior Rails experience, a structured process, and focused execution so your team keeps building while the upgrade moves forward.

The teams moving fastest right now aren't patching old dependencies. They're integrating AI.

Every month spent on maintenance debt is a month not spent connecting your product to LLMs, building intelligent workflows, or shipping the features your users are starting to expect. A modernized Rails stack isn't just less painful to maintain. It's what makes those integrations practical.

Clean APIs, current tooling, solid test coverage: that's the foundation you need to move fast with AI.

The honest comparison

Why teams choose Telos for Rails upgrades.

Rails upgrades aren't just extra engineering work. They require sequencing, risk management, and senior judgment so your product team can keep shipping.

Why Telos

Built for teams that need Rails to keep scaling.

Rails-native expertise

Telos has Rails experience across product builds, modernization engagements, and open-source contributions. Not generalist web development.

Senior team, start to finish

The same senior engineers who assess the system help execute the work. No handoffs to junior contractors mid-project.

Product-aware engineering

We don't treat the upgrade as isolated technical cleanup. We connect the work to product velocity, roadmap goals, and business risk.

AI-enabled where it helps

We use modern tooling to accelerate discovery, test analysis, code search, and repetitive upgrade tasks, without replacing senior engineering judgment.

Use cases

What this looks like in practice.

SaaS platform behind on Rails

A growing SaaS company is several major versions behind. The team wants to ship AI features and new customer workflows, but dependency conflicts and outdated patterns are slowing everything down.

We help

Assess risk, upgrade incrementally, clean up dependencies, stabilize tests, and build a safer foundation for new product work.

What's possible

Roadmap work continues while the platform gets modernized.

Internal platform with fragile tests

An internal Rails app runs critical workflows, but every release feels risky. The team knows the app needs to be upgraded, but low test coverage and old gems make the work hard to estimate.

We help

Improve test confidence, identify risky areas, sequence the upgrade, and support rollout.

What's possible

The team moves faster without treating every change like a fire drill.

Legacy app becoming a blocker

A business depends on a Rails application that still works, but the stack is making hiring, security, integrations, and new feature development harder every quarter.

We help

Modernize the app, upgrade Rails and Ruby, improve architecture where needed, and support the team through adoption.

What's possible

The app becomes a foundation again, not a constraint.
