If you're a Ruby on Rails developer or a business owner relying on a Rails application, you’re probably aware of the importance of staying up to date with the latest version of Ruby on Rails.
With Rails 8’s release in 2024, it’s time to start planning your Rails application upgrade strategy.
But the fact is, upgrading Rails isn’t always as simple as running a few commands. It involves assessing gem compatibility, addressing potential vulnerabilities, and ensuring a smooth transition without breaking your app.
You might be wondering if there is any tool that can help simplify your Rails upgrade process.
The answer is YES.
Here’s a game-changing tool in the market that makes this process significantly easier: RailsUp. RailsUp is created by RailsFactory, a top Clutch-rated Ruby on Rails development company in 2024.
In this blog, we’ll walk you through how to plan your Rails 8 upgrade using RailsUp, while also highlighting its features and benefits.
By the end of this Rails upgrade guide, you’ll have a clear roadmap for upgrading your project with minimal stress and maximum efficiency.
RailsUp: The Ultimate Rails Compatibility Checker Tool
RailsUp is a free tool developed by Rails Factory, designed to simplify one of the most daunting aspects of a Rails upgrade: assessing gem compatibility.

Here’s what makes RailsUp stand out:
Simplifies Complexity: Instead of manually checking each gem for compatibility, RailsUp automates the process.
Smarter Upgrades: By identifying and addressing compatibility issues early, it ensures a smoother upgradation process.
Risk Reduction: Post-upgrade surprises? Not with RailsUp. It highlights potential vulnerabilities so you can fix them beforehand.
Valuable Insights: Beyond compatibility, RailsUp provides actionable recommendations for keeping your gem dependencies up to date.
Best of all? It’s completely free to use. Yes, you read that right—no hidden costs, no premium tiers. Just a powerful tool at your fingertips.
Step-by-Step Guide to Planning Your Rails 8 Upgrade with RailsUp
Planning a Rails upgrade might sound overwhelming, but with RailsUp, it becomes a structured and manageable process. Let’s break it down step by step.
Step 1: Assess Your Current Application
The first step is understanding where you currently stand. Are you running Rails 7? Or are you still on an older version like Rails 6? Knowing your starting point is crucial because it determines the scope of the upgrade.
To get started:
- Navigate to RailsUp (or wherever the tool is hosted).
- Select the desired upgrade version.
- Upload your Gemfile.lock.
- Select the project size or the lines of code that your project currently has.
- Enter the number of custom gems and test coverage in percentage.
- If required you can toggle on the following buttons:
- Manual Testing Efforts (Toggle this on if you want to allocate time for manual testing)
- Parallel Development (Toggle this on if you want to continue of the same version while upgradation is in progress)
- Server Side Changes (Toggle this on if you want to account for efforts related to server-side changes)
- Code Refactoring (Toggle this on if you are planning to refactor the code during upgradation)
- Do you plan to replace any gems during upgradation?
- Do you need to perform any data conversion?
- Hit “Generate Report”
Within moments, RailsUp generates a detailed report covering three key areas:
- Gem Compatibility: Which gems are compatible with Rails 8, which need updates, and which are incompatible.
- Vulnerabilities: Any security risks associated with outdated gems.
- Complexity Level: An estimate of how challenging the upgrade will be based on the number of changes required.
This initial assessment gives you a bird’s-eye view of the work ahead. You can also download and save the detailed report.
Step 2: Review the Report and Prioritize Tasks
Once you have the report, take some time to review it thoroughly. Look for the following:
1. Incompatible Gems
These are the biggest roadblocks. If critical gems in your stack aren’t compatible with Rails 8, you’ll need to either find alternatives or wait for updates from the maintainers. RailsUp flags these clearly, saving you hours of detective work.
2. Outdated Gems
Outdated gems not only cause compatibility issues but may also expose your app to security vulnerabilities. RailsUp provides recommendations for updating these gems, helping you stay secure and compliant.
3. Vulnerability Report
Some issues are minor inconveniences, while others could derail your entire upgrade. RailsUp categorizes problems by severity, allowing you to prioritize high-risk items first.
Step 3: Estimate Time and Resources
One of RailsUp’s standout features is its ability to provide an estimated time frame for the upgrade. This is incredibly valuable when planning resources and setting expectations with stakeholders.
For example, if RailsUp estimates the upgrade will take 4 weeks, you can allocate team members accordingly or get Rails upgrade services from experts. You might decide to spread the work over a month or dedicate a sprint exclusively to the upgrade. Either way, having a realistic timeline helps prevent last-minute scrambles.
Step 4: Address Vulnerabilities and Update Dependencies
With RailsUp’s insights, you can systematically address vulnerabilities and update dependencies. Start with the highest-priority items marked as “critical” in the report. For instance:
- Replace deprecated methods with their newer counterparts.
- Update gems to their latest stable versions.
- Test thoroughly after each change to catch regressions early.
RailsUp doesn’t just tell you the criticality, but it also gives you the reason for it, making the process even smoother.
Step 5: Test it Thoroughly
Testing is non-negotiable during any Rails upgrade. Use automated tests to verify that everything works as expected post-upgrade. Pay special attention to:
- Integration points between different parts of your app.
- Third-party APIs and services.
- User-facing functionality to ensure no regressions slipped through.
If your test suite is robust, you’ll catch most issues before they hit production.
Step 6: Deploy Gradually
When you’re confident that your app is ready, consider deploying the upgraded version gradually. Use techniques like feature flags or rolling deployments to monitor performance and fix issues without affecting all users simultaneously.
Why Choose RailsUp Over Manual Methods?
You might wonder, “Can’t I just check Ruby gems compatibility myself?”
Technically, yes. But manual checks are time-consuming and prone to human error.
Here’s why RailsUp is a better choice:
- Speed: What would take days manually takes minutes with RailsUp.
- Accuracy: Automated tools reduce the risk of oversight.
- Comprehensive Insights: RailsUp goes beyond basic compatibility checks to include vulnerability assessments and complexity ratings.
- Cost-Effectiveness: As mentioned earlier, RailsUp is free. For small teams or startups, this is a huge advantage.
