Migrate Your Liberty Java Apps to Paketo Buildpack for Liberty

Posted by Marbenz Antonio on January 13, 2023

A guide has been created to assist in moving your application from Cloud Foundry to the Liberty Buildpack by Paketo.

IBM has announced the end-of-life for the liberty-for-java buildpack in Cloud Foundry, and users are in need of a migration option. The recommended solution is to use the Paketo Buildpack,, a cloud-native alternative. The key benefit of using Paketo Buildpack is the capability to convert application source code into consistent container images, which can be used across various platforms, providing greater flexibility and ease of updates.

Additional benefits of using the Paketo Buildpack for Liberty include the capability to construct your application image without the need for a Dockerfile, efficient rebuilds due to built-in caching, and simple modification and updating options.

What’s in the migration guide?

To simplify the migration process, we have created a guide that is divided into two primary parts: creating application using the Paketo Buildpack for Liberty, and advanced capabilities for applications. The guide contains a feature-by-feature comparison of Cloud Foundry and Paketo Buildpack commands in each section. These sections are intended to assist you in moving your application from Cloud Foundry to the Paketo Buildpack for Liberty.

The section of the guide on constructing application with the Paketo Buildpack includes the following steps:

• Building a container image from application source code
• Building an application with a simple war file
• Building an application from a Liberty server
• Building an application from a Liberty-packaged server
• Building an application by using UBI images

The section of the guide on advanced capabilities for Liberty applications that utilize the Paketo Buildpack for Liberty includes the following areas:

• Providing server configuration at build time
• Using Liberty profiles to build applications
• Installing custom features
• Installing interim fixes
