# Spring Boot 3 migration: I built a local CLI that generates risk estimates in minutes

Spring Boot 3 is not just another dependency bump.

For many teams, the upgrade from Spring Boot 2.x to 3.x bundles several migrations at once:

- Java 17+ baseline
- `javax.*` → `jakarta.*` namespace migration
- Spring Security 5 → 6 configuration changes
- Hibernate 5 → 6 compatibility risks
- dependency coordinate updates
- CI/runtime surprises

The hard question usually comes before implementation:

> **What will break, how risky is it, and how many sprints should we reserve?**

I built **Spring Upgrade Radar** as a local-first CLI to answer that planning question.

## What it does

It scans a Spring Boot Maven/Gradle project and generates:

- Executive summary (1-page overview for CTOs, EMs, tech leads)
- Risk score and readiness grade (e.g. 75/100, Grade B)
- Top migration risks (ranked by impact)
- Estimated roadmap (sprint-by-sprint)
- Recommended sprint backlog (prioritized)
- Migration tickets in multiple formats: JSON, Jira CSV, GitHub Issues Markdown

## Why local-first matters

Your source code does not need to leave your machine.

Many teams cannot upload production code to a hosted service. This tool runs locally, in your own CI, or on a private runner. The default workflow generates a full migration report without uploading source code.

## Quick start

```bash
git clone https://github.com/purewater02/spring-upgrade-radar.git
cd spring-upgrade-radar
python3 -m venv .venv
. .venv/bin/activate
pip install -e .

spring-upgrade-radar scan /path/to/your/spring-project \
  --target 3.5 \
  --output out/report.md \
  --html-output out/report.html \
  --tickets-json out/tickets.json \
  --jira-csv out/jira.csv \
  --github-issues-md out/github-issues.md
```

## Example output

Here's what the Executive Summary looks like for a typical Spring Boot 2.7 → 3.5 project:

```markdown
# Executive Summary

- Spring Boot: 2.6.2 → 3.5
- Java: 8
- Risk score: 100/100 | Grade: C (Critical)

## ⚠️ Top 3 Risks
1. Spring Boot 2.x → 3.x major migration
2. Java 17 baseline gap
3. JPA javax.persistence imports

## 🗺️ Estimated Roadmap
- Sprint 1: Java 17+ build/runtime baseline — Estimated Time: 2 weeks
- Sprint 2: javax → jakarta namespace migration — Estimated Time: 2 weeks
- Sprint 3: dependency major upgrades — Estimated Time: 2 weeks
- Sprint 4: Spring Boot 3.x migration validation — Estimated Time: 1 week
```

A full report includes evidence for each finding and actionable ticket exports for Jira and GitHub Issues.

## Current check scope

v0.1.1 covers intentionally narrow checks:

- Spring Boot 2.x → 3.x migration risk
- Java baseline compatibility
- Jakarta Persistence import migration (`javax.persistence` → `jakarta.persistence`)
- Spring Security legacy configuration patterns
- JSP/JSTL Jakarta compatibility risks
- MySQL Connector/J coordinate migration
- Wrapper/CI execution readiness

More rules will be added in subsequent releases.

## Feedback wanted

This is an early v0.1.1 release. I am especially interested in:

- Real-world Spring Boot 2.x projects where this tool could have saved time
- Edge cases and checks that are missing from v0.1.1
- Feedback on the report format — is it useful for your team?

Please file an issue on GitHub or open a discussion.
```

### Publishing checklist

- [ ] Upload `docs/social-preview.png` as featured image
- [ ] Verify all links render correctly on dev.to
- [ ] Add the post to a relevant collection (e.g. "Open Source Tools")
- [ ] Pin a comment with the GitHub link for visibility
- [ ] Share the dev.to URL on LinkedIn, Twitter/X, and Reddit after publishing

## LinkedIn post

Spring Boot 2.x → 3.x migrations are hard to estimate because multiple changes land together:

- Java 17+ baseline
- `javax` → `jakarta`
- Spring Security 6
- Hibernate 6
- dependency and CI compatibility issues

I built **Spring Upgrade Radar**, a local-first CLI that scans a Spring Boot project and generates a migration planning report:

- risk score
- executive summary
- top risks
- estimated roadmap
- sprint backlog
- Jira/GitHub-ready migration tickets

It is open source and runs locally, so source code does not need to leave your machine.

Landing page: https://purewater02.github.io/spring-upgrade-radar/  
GitHub: https://github.com/purewater02/spring-upgrade-radar/

If your team is still planning a Boot 3 migration, I would appreciate feedback from real projects.

## Reddit r/java draft

### Title

I built a local-first CLI that estimates Spring Boot 2.x → 3.x migration risk

### Body

Hey r/java,

I built an early open-source tool called **Spring Upgrade Radar** for teams planning Spring Boot 2.x → 3.x upgrades.

The goal is not automatic rewriting. It is migration estimation:

- scan a Maven/Gradle Spring Boot project locally
- detect Java 17 baseline gaps, `javax` → `jakarta` imports, legacy Spring Security config, JSP/JSTL risks, dependency coordinate issues, etc.
- generate a risk score and executive summary
- create an estimated roadmap and sprint backlog
- export migration tickets as JSON, Jira CSV, and GitHub Issues Markdown

Landing page: https://purewater02.github.io/spring-upgrade-radar/  
Repo: https://github.com/purewater02/spring-upgrade-radar/

It is v0.1.1, so the rule coverage is intentionally narrow. I would love feedback from people who have done real Spring Boot 3 migrations: what checks would have saved you the most time before starting?

## Reddit r/SpringBoot draft

### Title

Local-first Spring Boot 3 migration radar: risk score, roadmap, and ticket exports

### Body

I put together a small open-source CLI for Spring Boot 2.x → 3.x migration planning.

**Spring Upgrade Radar** scans your project locally and generates:

- executive summary
- risk score / readiness grade
- top migration risks
- estimated roadmap
- recommended sprint backlog
- migration tickets
- JSON, Jira CSV, and GitHub Issues Markdown exports

Current checks include Java 17 baseline, Spring Boot 2 → 3 risk, `javax.persistence` / servlet validation imports, Spring Security legacy config, JSP/JSTL Jakarta compatibility, MySQL Connector/J coordinates, and wrapper/CI readiness.

Docs: https://purewater02.github.io/spring-upgrade-radar/  
Repo: https://github.com/purewater02/spring-upgrade-radar/

It is local-first by default; no hosted upload is required.

If you have a real-world Boot 2.7 app, I would be interested in hearing which migration risks this misses.

Show HN: Spring Upgrade Radar – local CLI for Spring Boot 3 migration estimates

### Body

I built Spring Upgrade Radar, a local-first CLI for planning Spring Boot 2.x → 3.x migrations.

It scans a Maven/Gradle Spring Boot project and generates a migration planning report: risk score, executive summary, top risks, estimated roadmap, sprint backlog, and ticket exports for JSON/Jira/GitHub Issues.

The goal is not automatic code rewriting. It is answering the planning question teams usually ask first: “what will break, and how many sprints should we reserve?”

## X / Twitter thread

### Post 1

Spring Boot 2.x → 3.x migration planning just got easier.

I built Spring Upgrade Radar: a local-first CLI that scans your project and generates a migration risk report, estimated roadmap, and Jira/GitHub-ready tickets.

https://github.com/purewater02/spring-upgrade-radar/

### Post 2

Why it exists:

Spring Boot 3 upgrades often combine several migrations:

- Java 17+
- javax → jakarta
- Spring Security 6
- Hibernate 6
- dependency compatibility
- CI/runtime surprises

The hard part is estimating risk before starting.

### Post 3

What it generates:

- executive summary
- risk score + readiness grade
- top risks
- estimated roadmap
- sprint backlog
- Markdown/HTML report
- JSON, Jira CSV, GitHub Issues exports

Runs locally by default.

### Post 4

Quick start:

```bash
git clone https://github.com/purewater02/spring-upgrade-radar.git
cd spring-upgrade-radar
pip install -e .
spring-upgrade-radar scan /path/to/project --target 3.5 --output out/report.md
```

## Short cold outreach draft

Hi — I’m building Spring Upgrade Radar, a local-first tool that estimates Spring Boot 2.x → 3.x migration risk and generates a roadmap/ticket backlog.

If your team still has Boot 2.x services, I’d be happy to generate a free sample migration report and hear whether the findings match your real upgrade concerns.
