MF COBOL to IBM COBOL Migration
Modernize COBOL Applications with Mainframe-Grade Performance and Reliability
A Scalable Migration Strategy to Shift from Distributed to Enterprise COBOL Workloads
Introducing MF COBOL to IBM COBOL migration, a strategic offering that moves your COBOL applications from distributed environments to mainframe-optimized platforms. The migration boosts performance, contains costs, and positions your legacy applications for enterprise-wide modernization, taking advantage of the strength of IBM COBOL for z/OS.
What is MF COBOL?
MF COBOL (Micro Focus COBOL), now Rocket Visual COBOL, is a modern COBOL implementation for developing business applications for multiple platforms including Windows, Unix, and Linux. It provides basic-level interactions with Visual Studio and supports native and .NET managed code, enabling integration of legacy systems with modern codebases. MF COBOL offers features like XML support, enhanced UI handling, powerful sorting, and developer tools.
What is IBM COBOL?
IBM COBOL for z/OS, especially the Enterprise edition, is a premier compiler for IBM Z mainframes. It allows enhanced performance, reduced CPU usage, and the ability to modernize COBOL applications through support for web, cloud, and mobile access. It includes native UTF-8 support, JSON/XML interoperability, and integration with transactional systems such as CICS, IMS, and Db2—ideal for mainframe COBOL migration projects.
Business Challenges with MF COBOL
- High Maintenance Costs: Implementation of MF COBOL on distributed platforms can result in increased running costs owing to infrastructure and maintenance requirements.
- Inflexibility: Legacy applications developed using MF COBOL can find it difficult to accommodate changing industry needs and technological changes.
- Upgrade and Compatibility Issues: Upgrades and compatibility with new platforms or technologies may be difficult to handle.
- Shortage of MF COBOL Skills: The limited availability of proficient MF COBOL programmers can make maintenance and modernization processes challenging.
- Complexity in Integration: Integrate MF COBOL with new technologies may be complicated, involving more setup and resources for compatibility.
- Modernization Challenges: Enterprises aiming to modernize COBOL applications often find MF COBOL environments lacking in agility.
