I will write a spring boot upgrade readiness report for your java app
Jeff S
Over deze dienst
Java teams on Spring Boot 2.7 or 3.x: find out what the upgrade to Spring Boot 4.1 takes before you start it.
Free support ended on 30 June 2023 for Spring Boot 2.7 and on 30 June 2026 for 3.5, the last 3.x line.
WHAT YOU GET (a PDF, within 3 days)
The verdict in three lines
Your versions next to what 4.1 manages
The upgrade path in steps
Every blocker, ranked, with where it is and the fix
Behaviour changes to test
An effort estimate, marked as an estimate
What was not checked
See the sample in the gallery: a real five-page report on the public PetClinic app, 2.7.3 to 4.1.
WHAT I NEED
Your build file (Maven or Gradle)
Your dependency tree
The output of one command that counts framework imports. It prints package names and counts, none of your code.
No repo access. No source code. No call.
WHAT THIS IS NOT
I don't do the upgrade or run your app. The report is advice from one engineer's reading of your build against the official Spring Boot migration guides, with no warranty. It is not a security audit.

I'm Jeff, a Java engineer. I've spent decades building the systems big companies run on. Here I do one thing: I read your Spring Boot build and write up what stands between your app and a supported version. You get the blockers ranked, the behaviour changes to test, the order to do it in and a rough size for the work. Fixed price, three text files from you, no repo access and no calls.
Veelgestelde vragen
Do you need access to my repository?
No. I work from three text files: your build file, your dependency tree, and the output of one command that counts framework imports.
Can you report on more than one app?
One app per order. Order again for the next one.
Will you do the upgrade?
No. You get the plan; your team does the work.
