 # Symphony BDK Reference Documentation
 
+> [!NOTE]
+> BDK version 3.0: Major change !
+> 
+> The newly introduced BDK version 3.0 relies on Java 17 and SpringBoot 3. This is a major change that allows Symphony to continue to propose the latest security fixes following the end of support of Spring Boot 2 and also to keep up with the latest evolutions of Java.
+> 
+> For the next 6 months Symphony will provide critical security fixes for BDK 2.0 where possible (since Spring gives no guarantees for their packages).
+> 
+> Please consider migrating your Bots in the coming months to benefit from the latest features and support. 
+
+> [!IMPORTANT]
+> As detailed above, the BDK version 2.0 will stop being supported by Symphony on August 15.
+
 This reference guide provides detailed information about the Symphony BDK. It provides a comprehensive documentation
 for all features and abstractions made on top of the [Symphony REST API](https://developers.symphony.com/restapi/reference/introduction).

+# Migration guide to Symphony BDK 3.0 from 2.0
+
+This guide provides information about how to migrate from Symphony BDK 2.0 to BDK 3.0. Migration for the following topics will be detailed here:
+- JDK17
+- Dependencies
+
+## JDK17
+The major change in BDK 3.0 is the migration from JDK8 to JDK17, this migration requires 
+- IDE update
+- Package naming change
+- New compiler argument in build tool
+
+### IDE update
+BDK Bot developers needs install JDK17 in their development environment, and configure IDE to used JDK17 instead of JDK8.
+
+
+### Package naming change
+Replace all `javax.xxx` package imports to `jakarta.xxx`.
+
+Java BDK 2.0
+
+```java
+    import javax.ws.rs.ProcessingException;
+```
+Java BDK 3.0
+
+```java
+    import jakarta.ws.rs.ProcessingException;
+```
+
+### New compiler argument in build tool
+
+A new `-parameters` argument must be passed to the compiler, so that `@Slash` commands and/or other java annotations continue to work
+with JDK17.
+
+#### Maven
+
+```xml
+    <plugin>
+        <groupId>org.apache.maven.plugins</groupId>
+        <artifactId>maven-compiler-plugin</artifactId>
+        <version>${maven.compiler.version}</version>
+        <configuration>
+            <compilerArgs>
+                <arg>-parameters</arg>
+            </compilerArgs>
+        </configuration>
+    </plugin>
+```
+
+#### Gradle
+```groovy
+    tasks.withType(JavaCompile) {
+        options.encoding = 'UTF-8'
+        options.compilerArgs << '-parameters'
+    }
+```
+
