# Jakarta EE Namespace Migration Skill
## Overview
Spring Boot 3.0 has upgraded from Java EE to Jakarta EE APIs for all dependencies. This is one of the most significant breaking changes and requires updating all `javax.*` package imports to `jakarta.*`.
**Important:** Packages such as `javax.sql.*` and `javax.crypto.*` will NOT change to `jakarta.*` as they are part of the Java 17+ JDK itself, not part of Java EE.
## Required Package Mappings
| Before (Java EE) | After (Jakarta EE) |
|------------------|-------------------|
| `javax.persistence.*` | `jakarta.persistence.*` |
| `javax.validation.*` | `jakarta.validation.*` |
