IBM COBOL Elevate for z/OS is designed to bring together three complementary capabilities to help organizations optimize, upgrade and streamline performance of COBOL applications.
1. Accelerate
IBM COBOL Elevate for z/OS does upfront performance analysis to determine what COBOL programs require optimization. It is built to identify COBOL programs that require optimization through a simple, one-time setup and assist with the optimization process. The identified COBOL applications are optimized without source code changes, need for recompilation or extensive performance analysis activities.
IBM COBOL Elevate is built to reduce pre-deployment testing effort for optimized COBOL modules enabling organizations to unlock additional value from existing COBOL applications.
2. Upgrade
The Simplify Compiler Upgrades capability is designed to help organizations speed-up upgrade to supported Enterprise COBOL compiler levels.
Through automated inventory analysis, readiness assessments, AI-assisted remediation, and guided workflows, teams can better understand application dependencies, identify upgrade requirements and predict project risk. This helps organizations maintain currency while taking advantage of the latest Enterprise COBOL and IBM Z innovations.
3. Performance insights
Performance Insights helps organizations identify and prioritize potential performance issues directly within COBOL source code. Using static and dynamic analysis together with real execution data, IBM COBOL Elevate delivers actionable recommendations that help developers focus on the identified issues with the greatest impact. By connecting analysis directly to source code, organizations can move quickly from identification to remediation.
Organizations are looking for practical ways to modernize existing applications while maintaining the reliability and resilience that their businesses depend on.
IBM COBOL Elevate for z/OS is built to help address key COBOL application modernization challenges by:
- Optimizing COBOL application performance by fully leveraging Z platform capabilities, maximizing ROI
- Supporting proactive performance management
- Accelerating COBOL application modernization and compiler upgrade initiatives
- Reducing dependency on scarce COBOL skills and development resources
Together, these capabilities are designed to help organizations modernize with greater speed while continuing to leverage the business logic and operational stability embedded within their COBOL applications.
IBM COBOL Elevate for z/OS 1.1 is planned for availability beginning 18 September 2026. For additional information about IBM COBOL Elevate for z/OS, contact your IBM representative or IBM Business Partner.
