Lift-and-Shift of Legacy JBoss Applications May Not Be Achievable on Tanzu Platform 10.3.5

Products

• VMware Tanzu Platform Core

Issue/Introduction

Lift-and-shift of legacy JBoss applications to Tanzu Platform 10.3.5 may not be achievable.

Customers attempting this migration may encounter issues both with JBoss-oriented buildpack-based approaches and with deployments repackaged to run with the standard Java Buildpack.

Environment

• Tanzu Platform 10.3.5
• Legacy JBoss-based applications
• Lift-and-shift or containerization migration scenarios
• Deployments using either:
• a JBoss-oriented custom/community buildpack approach
• the standard Java Buildpack-based deployment approach

Cause

 This limitation can be associated with multiple factors, including:

• supportability constraints for JBoss-oriented buildpack-based deployment approaches
• incompatibility issues encountered for some configurations when attempting to run legacy JBoss applications using the standard Java Buildpack

Resolution

Broadcom recommends the following:

1. Do not position lift-and-shift of legacy JBoss applications on Tanzu Platform 10.3.5 as a generally reliable migration approach.
2. Use the java buildpack and manually configure the Maven/Gradle wildfly plugin to run the application as a standalone Java application
3. Re-evaluate the scenario on a later release if this use case is expected to improve.
