Apache Camel 4.x Upgrade Guide

If you are migrating from Camel 3.x then use the Camel 3.x to 4.0 Migration Guide first.

This document is for helping you upgrade your Apache Camel application from Camel 4.x to 4.y. For example, if you are upgrading Camel 4.0 to 4.2, then you should follow the guides from both 4.0 to 4.1 and 4.1 to 4.2.

You can find the upgrade guide for each release in the following pages:

Upgrade guide 4.0 → 4.1
Upgrade guide 4.1 → 4.2
Upgrade guide 4.2 → 4.3
Upgrade guide 4.3 → 4.4
Upgrade guide 4.4 → 4.5
Upgrade guide 4.5 → 4.6
Upgrade guide 4.6 → 4.7
Upgrade guide 4.7 → 4.8
Upgrade guide 4.8 → 4.9
Upgrade guide 4.9 → 4.10
Upgrade guide 4.10 → 4.11
Upgrade guide 4.11 → 4.12
Upgrade guide 4.12 → 4.13
Upgrade guide 4.13 → 4.14
Upgrade guide 4.14 → 4.15

The Camel Upgrade Recipes project provides automated assistance for some common migration tasks. Note that manual migration is still required. See the documentation page for details.
