Upgrading 1,000+ Spring and Java applications in a single 24-hour window for a global financial institution

Global Financial Institution

A global financial institution upgraded over 1,000 Spring and Java applications in a single 24-hour window using AceMQ's deterministic Spring upgrade process, achieving significant CPU and memory reductions through Broadcom's commercial Spring support.

Overview

Broadcom's commercial Spring support enables a deterministic upgrade methodology that compresses what would normally be a multi-quarter Java and Spring upgrade project into a single execution window. AceMQ facilitates access to this methodology through its Broadcom partnership, having supported financial institutions completing enterprise-scale Spring upgrades in compressed timeframes.

Challenge

Large financial institutions running hundreds or thousands of Spring applications face a continuous challenge keeping up with Java LTS releases and Spring version upgrades. The typical approach — upgrading applications team by team — creates a years-long tail of legacy versions and security exposure.

Environment

Enterprise financial services; 1,000+ Spring / Java applications; cloud deployment; migrating from legacy Java 8/11 to Java 17/21 with Spring Framework version upgrades.

Approach

Broadcom's Spring App Advisor tool analyzes application codebases to identify compatibility issues before upgrade execution, enabling a high-confidence batch upgrade process. AceMQ connects customers to this methodology through its Broadcom partnership, providing the commercial Spring support access required to leverage the deterministic upgrade tooling.

Solution

  1. Spring App Advisor analysis across all application codebases
  2. Compatibility issue identification and pre-upgrade remediation
  3. Deterministic batch upgrade execution plan
  4. Java LTS migration (Java 8/11 → Java 17/21) alongside Spring version upgrades
  5. Post-upgrade validation and regression testing framework
  6. CPU and memory optimization measurement and reporting

Outcome

Financial institutions leveraging Broadcom's deterministic Spring upgrade methodology through AceMQ have completed enterprise-scale application portfolio upgrades in dramatically compressed timeframes, reducing technical debt, improving security posture, and achieving measurable infrastructure cost reductions.
