This is the 2nd blog post in a series of migration blogs to provide details and help for users to Camel 4. The first blog post that focus on general migration principles can be found here.

This blog post introduces a Camel Upgrade Recipes project and shows an example of its usage. Introduction Migrating Apache Camel code can often be a tedious and error-prone process, especially when it involves repetitive tasks like renaming classes, updating method signatures, or adapting to new Camel API changes. To address this need, Camel Upgrade Recipes project based on OpenRewrite was developed. The project is not designed to provide fully automated migration but rather to assist with manual migrations, making them more efficient and less error-prone.
