PHP2Shell (CVE-2026-109618 and CVE-2026-109619) went public on 21 October 2026 and is the most serious PHP flaw in years, scored 9.2 out of 10. It lets an attacker run code on a server without logging in, and PHP 8.1 or older will never get a fix. Don't worry: we put your core PHP features on Spring Boot and get them live in 7 days, with bigger systems moved in phases. Read the PHP2Shell breakdown.
Our PHP to Spring Boot migration services in USA and UK markets are for companies whose PHP back end has outgrown the people and tools around it. Your IT department already runs Java, your auditors ask for typed, tested code, or your app now talks to an ERP, a message queue and three partner APIs. Spring Boot was made for that kind of work.
We rebuild the business rules you have in PHP as a Spring Boot 3 service on Java 21. Database access goes through Spring Data JPA with Hibernate, schema changes are tracked with Flyway, logins and roles move to Spring Security, and health checks and metrics come from Spring Boot Actuator. The result is one deployable jar that your ops team can run on a VM, in Docker or on Kubernetes.
Techno Mantraa has more than a decade of web development behind it. Our developers sit in Gujarat, India and keep a working overlap with the US East Coast and the UK, so a Java rewrite does not mean waiting a day for every answer.
Why companies move PHP code to Spring Boot
Spring Boot is not the quickest way to build a small website. It earns its place when the code carries money, compliance or many integrations and needs to stay maintainable for the next ten years.
Type checking before release
The Java compiler catches wrong types, missing fields and renamed methods at build time, long before a customer hits a blank page in production.
Fits enterprise systems
Spring has mature clients for Kafka, RabbitMQ, LDAP, SOAP, JDBC databases and every major cloud, so links to the systems around you are standard work, not custom glue.
Easy to run and watch
Actuator endpoints, structured logs and Micrometer metrics plug into Prometheus, Grafana or Datadog, so your ops team sees what the app is doing.
What moves from PHP to Spring Boot
- PHP controllers and scripts rebuilt as Spring MVC REST controllers
- SQL queries turned into JPA entities and Spring Data repositories
- Database schema versioned with Flyway, existing data kept as it is
- PHP sessions and logins replaced by Spring Security, old password hashes still accepted
- Cron jobs moved to Spring scheduled tasks or a job runner
- Payment, email and partner API calls rewritten with Spring clients
- Unit and integration tests written with JUnit 5 and Testcontainers
- Docker image, CI pipeline and deployment to your cloud or servers
How the first 7 days of your Spring Boot move work
Day 1: Code map and scope
We trace every PHP entry point, table and outside call, decide what goes into the first release and fix the price in writing.
Days 2-4: Build the service
We create the Spring Boot project, map tables to JPA entities, then port each module's rules into services with tests beside them.
Days 5-6: Compare old and new
The same requests go to the PHP app and the Java service, and we check that the answers and the stored data match before you sign off on staging.
Day 7: Switch over
Traffic for the migrated part moves to Spring Boot behind your load balancer, with the PHP version on standby until you are happy.
PHP back end vs Spring Boot
A side by side view of what your team works with before and after the move.
| Legacy PHP back end | Spring Boot service | |
|---|---|---|
| Language | Loosely typed PHP, errors found at runtime | Java 21 with compile-time checks |
| Data access | Hand-written SQL strings | JPA entities, repositories and Flyway scripts |
| Security | Home-made login and role checks | Spring Security with OAuth2 and method-level rules |
| Monitoring | Log files on the server | Actuator health, metrics and tracing |
| Integrations | cURL calls copied between files | Typed HTTP clients, Kafka and RabbitMQ support |
| Support window | Old PHP releases with no fixes | Long-term support Java releases and regular Spring updates |
Why our team for a Spring Boot rewrite
A move from PHP to Java changes the language, the runtime and often the hosting. We keep the business behaviour fixed while everything under it changes.
Behaviour checked against the old app
We record real requests and responses from your PHP system and replay them against Spring Boot, so a rule hidden in an old file does not get lost.
Fixed quote per phase after a free audit, never an open-ended hourly bill.
Mutual NDA in place before you share the repository.
Spring Boot migration for USA and UK companies
This service is built for mid-sized firms in the United States and the United Kingdom whose PHP platform now has to sit next to Java systems, banks or larger partners. Our hours cover the US Eastern morning and the full UK afternoon, and messages get a reply the same working day.
Hiring a Java team locally in New York or London is expensive and slow. An offshore Spring Boot team from India costs far less, works to a fixed price and an NDA, and hands over clean code your own staff can take on.

Frequently asked questions
Straight answers about our PHP to Spring Boot Migration service.
A small or medium PHP back end can move to Spring Boot in 7 days. A Java rewrite of a large system is honest work that takes longer, so big apps get a phased plan: the first module goes live within those 7 days and the rest follows in agreed stages.
Yes, and for larger systems we recommend it. Both share the same database while routes move across one module at a time, so users never face a big-bang switch.
It can be. For a brochure site or a simple shop, a PHP 8.4 upgrade or Laravel is cheaper. Spring Boot pays off when you have heavy integrations, strict audit needs or an in-house Java team.
For every part that has moved, yes, because PHP is no longer running it. Anything still on PHP during a phased move gets upgraded to a patched PHP 8.4 release so nothing is left exposed.
The price depends on the number of modules, tables and integrations. After a free audit you get a fixed quote for each phase, so the budget is clear before work begins.
Yes. We plan calls inside US Eastern and UK business hours, reply the same day, sign your NDA and give you one project lead who knows your Spring Boot project.
