End-of-Life Tracking · Step-by-Step Upgrades · Tested Before Release · Rollback Ready
Upgrade Your Framework and Runtime Before Support Ends
Your app runs on runtimes, frameworks or databases that are out of support or close to it. We plan and deliver step-by-step upgrades to supported versions, tested so nothing breaks for your users.
What Are Version Upgrade Services?
Version upgrade services move a live application onto newer, supported versions of the software it is built on, such as the runtime, framework, language, database and key libraries, without breaking features or losing data. The work covers assessing what must change, updating code for breaking changes, testing, releasing in safe steps and leaving the application on versions that receive security fixes.
Codersarts provides framework and version upgrade services for web applications, APIs and SaaS products. We upgrade Node.js, PHP, Python, React, Next.js, Angular, Vue, Laravel, Django, Express, NestJS, PostgreSQL, MySQL and more, planning each upgrade step by step so your users see no disruption and your team gets a codebase that is easier and safer to maintain.
Every framework and runtime has an end-of-life date. We move your application to supported versions before that date turns into a security risk.

Why Version Upgrades Cannot Wait
Software versions do not last forever. Each runtime, framework and database publishes a support schedule, and once a version reaches end of life it stops receiving security fixes.
Security. Vulnerabilities found after end of life stay unpatched, and scanners and auditors flag them
Hosting platforms drop old versions. Cloud and serverless platforms remove support for old runtimes, which can block deployments
Libraries move on. New versions of packages require newer runtimes and frameworks, so outdated apps cannot install security fixes
Compliance and customers. Security questionnaires and audits ask whether software is supported
Hiring and handover. Developers are harder to find for outdated stacks, and older codebases take longer to understand
Cost of delay. Each skipped version adds to the next upgrade, turning a short task into a large project
Recent examples show how quickly this happens. Node.js 20, MySQL 8.0 and Django 4.2 all reached the end of their support in April 2026, and Laravel 11 reached end of life in March 2026. Applications still running on those versions now need a planned upgrade.
Common Upgrade Paths We Handle
Technology | Typical upgrade | What usually changes |
|---|---|---|
Node.js | Older LTS line to the current LTS line | Native modules, deprecated APIs, package compatibility, ES module changes |
PHP | PHP 7.x to 8.x | Stricter typing, removed functions, changed error handling |
Python | Older 3.x release to a supported release | Library compatibility, removed modules, typing changes |
React | Class components and old lifecycles to modern React | Deprecated APIs, rendering changes, testing library updates |
Next.js | Pages Router to newer releases or the App Router | Routing, data fetching, middleware and build configuration |
Angular | Several major versions forward | Stepwise updates through each major version, dependency upgrades |
Vue | Vue 2 to Vue 3 | Composition API, removed features, ecosystem library replacements |
Laravel | Older major release to a supported release | Configuration structure, package updates, PHP version requirement |
Django | Older LTS to the current LTS | Deprecated features, database backends, third-party apps |
PostgreSQL and MySQL | Older major version to a supported version | Query behaviour, configuration, replication and backups |
Our Version Upgrade Process
Inventory. We list every runtime, framework, database and library version in use, with its support end date.
Assessment. We read the official upgrade guides and changelogs, scan the code for deprecated features and estimate the effort for each step.
Upgrade plan. You receive a plan showing the order of upgrades, the risks, the testing approach and the estimate. Nothing starts without your approval.
Safety net. Before changing anything, we make sure there are tests or scripted checks for the most important user flows, such as sign-up, login, payments and key reports.
Step-by-step upgrades. We move one major version at a time on a separate branch, fixing breaking changes and keeping the app working at each step.
Testing. Automated tests, manual checks of key flows and a comparison of behaviour before and after.
Staged release. The upgraded app runs on staging first, then production, through your normal deployment process, with the previous version ready for rollback.
Monitoring and clean-up. We watch errors and performance after release, then remove temporary compatibility code.
Step-by-Step Upgrades vs Big-Bang Upgrades
Approach | How it works | Risk |
|---|---|---|
Big-bang | Jump straight to the latest version of everything in one release | High: many changes at once make problems hard to trace and roll back |
Step-by-step | Move one major version or one component at a time, releasing in between where practical | Lower: each change is small, tested and reversible |
Parallel run | Run old and new versions side by side and switch traffic gradually | Lowest for critical systems, with extra infrastructure for a short time |
For most applications, we recommend step-by-step upgrades, released in small batches.
Upgrading Without Tests
Many older applications have few or no automated tests, which makes upgrades feel dangerous. We handle this in three ways:
Characterisation tests. We record how key features behave today, then check the upgraded app behaves the same way
End-to-end checks for the user flows that matter most to your business
Error monitoring with tools such as Sentry, so any new error after release is seen and fixed quickly
These tests stay in your repository afterwards, which makes every future upgrade faster.
Database Version Upgrades
Database upgrades need extra care because they involve your data. We take a full backup and test the restore, rehearse the upgrade on a copy, check query behaviour and performance on the new version, and plan the production upgrade for a low-traffic window. Where downtime must be minimal, we use replication-based upgrades. Larger database work, such as changing database engines, follows our Database Migration process.
Example Upgrade Plan
This illustrative plan is for a Node.js and React application several versions behind.
Step | Work | Release |
|---|---|---|
1 | Add end-to-end checks for sign-up, login, checkout and reports | No user-facing change |
2 | Update minor versions of all libraries and fix deprecation warnings | Released on its own |
3 | Move Node.js to the current LTS line and fix native module issues | Released on its own |
4 | Upgrade React and its testing libraries, updating deprecated patterns | Released on its own |
5 | Upgrade the build tool and remaining major libraries | Released on its own |
6 | Remove compatibility code and update documentation | Final clean-up release |
Each step is small enough to test fully and roll back on its own, so a problem never blocks the whole upgrade.
Upgrading Mobile and Cloud Platforms
Upgrades are not limited to application code. Mobile apps must meet yearly Apple and Google build requirements, and cloud platforms retire old runtimes for serverless functions and managed services. We include these platform upgrades in the same plan where they apply. For mobile apps, see Mobile App Maintenance.
Upgrade, Refactor or Rewrite?
Option | What it means | When it fits |
|---|---|---|
Upgrade | Move to supported versions, changing code only where needed | The app works well and its design is sound |
Refactor | Improve the structure of specific parts during or after the upgrade | Some areas are hard to change or cause repeated bugs |
Rewrite | Rebuild the application on a new stack | The current stack is abandoned or the design blocks the business |
Rewrites are expensive and risky, so we recommend them only when an upgrade is genuinely not possible. In most cases, a planned upgrade plus targeted refactoring delivers the benefits at a fraction of the cost.
Signs Your Application Needs an Upgrade
Security scanners report vulnerabilities that can only be fixed by upgrading the framework or runtime
Your hosting provider has sent end-of-support notices for your runtime or database version
New packages refuse to install because they require newer versions
Developers avoid touching the code because changes break things in unexpected ways
The app runs on versions released many years ago, and nobody knows the support dates
Keeping Upgrades Small in Future
After the upgrade, we recommend regular maintenance so you never face a large upgrade again: monthly dependency updates, planned runtime upgrades each year, and end-of-life tracking in a simple calendar. This ongoing work is part of Security Patching and Updates within our monthly Managed Run service.

Upgrade Assessment and Plan
We review your application, list every version and its support status, and estimate each step of the upgrade. The assessment is charged at $50 per hour, usually a few hours for a typical application, and you approve the estimate before any work starts.
Upgrade Work
Charged at $50 per hour against the approved estimate. If the estimate needs to change, we explain why and ask for approval before continuing.
Ongoing Updates
Regular dependency and runtime updates are included in Managed Run, starting at $1,000 per month.
If your app was handed over by a previous developer, the upgrade can begin with a Take Over Existing App review.
What Is Not Included
New features added during the upgrade, which are quoted separately
Full redesigns or rewrites onto a different stack
Third-party licence or platform costs
Upgrades of software you do not control, such as a vendor's hosted platform
Frequently Asked Questions
What are version upgrade services?
They move a live application onto newer, supported versions of its runtime, framework, language, database and libraries, with testing and a safe release so nothing breaks for users.
Why should I upgrade if my app works fine?
Unsupported versions stop receiving security fixes, hosting platforms drop them, and new libraries stop working with them. Waiting makes the eventual upgrade larger and riskier.
How long does a framework upgrade take?
Minor upgrades can take a few days. Jumps across several major versions, or apps with few tests, can take several weeks. We estimate each step after review.
Will the upgrade cause downtime?
Usually not. Upgrades are tested on staging and released through your normal deployment process, with rollback ready. Database upgrades may need a short planned window.
Can you upgrade PHP 7 to PHP 8 or Vue 2 to Vue 3?
Yes. We handle PHP, Node.js, Python, React, Next.js, Angular, Vue, Laravel, Django and database upgrades, including major version jumps.
What if my app has no tests?
We add characterisation and end-to-end checks for key user flows before upgrading, so we can confirm the app behaves the same afterwards.
How much do version upgrades cost?
Assessment and upgrade work are charged at $50 per hour against an estimate you approve in advance.
Should we upgrade or rewrite?
In most cases a planned upgrade with targeted refactoring is faster and cheaper. We recommend a rewrite only when the current stack is abandoned or the design blocks the business.
