Fujitsu Mainframe Withdrawal Accelerates Migration; Are You Considering Post-Migration Maintenance and Operations? With Fujitsu's withdrawal from the mainframe business, many companies are seriously considering migrating their core systems. However, the COBOL and JCL assets that have been operated for many years are increasingly becoming black boxes, and it's not uncommon for design documents to be insufficient. As a result, migration plans themselves are increasingly stalled due to reasons such as: - Inability to grasp the overall picture of current assets - Inability to estimate migration costs and duration - Inability to explain to management, hindering budget allocation Furthermore, in recent years, even after migration is completed, companies find that modifications and operations require more effort than anticipated, leading to the feeling that "maintenance has become more difficult than before." What is needed now is not just system migration, but the realization of an environment that allows for continued maintenance and operation after migration.

Migrations Without Design Documents Make Post-Migration Maintenance Difficult Traditional migrations have often employed "straight conversion," which converts existing programs to new ones. However, while the code may be migrated, the design philosophy and business specifications are not adequately documented before moving to operation, leading to a decline in maintainability. As a result, issues arise such as: - Difficulty in understanding the scope of impact during failures or modifications - Difficulty in handover to maintenance personnel - Increasing effort for investigation and modification year by year This creates a situation where "successful migration" does not automatically translate to "ability to maintain." In other words, the crucial point is not just which migration method to choose, but how to achieve a system that can be continuously maintained after migration.

How to Achieve Migration to a Maintainable System Through AI-Generated Design Documents This seminar will explain how to achieve migration with maintainability in mind. We will introduce an approach that uses AI to reverse-engineer design documents from existing source code, and then build a new system based on those documents. This method allows for a migration process that considers everything from visualizing current assets to migration decisions and post-migration maintainability. We will also cover specific concepts useful for both "companies planning to migrate" and "companies that have already migrated but face maintenance challenges," including partial support for design document creation and test efficiency improvements. We will also introduce the "Simple Migration Diagnosis" service, which is available free of charge.

- Recommended for individuals in the following positions / facing these challenges: - Information Systems and IT Planning departments considering migration of Fujitsu mainframes (GS21 series, etc.) - Those struggling with migration planning and budget allocation due to the black-boxing of COBOL/JCL assets - Those who want to organize decision-making criteria for choosing between rehost, rewrite, or rebuild migration methods - Those who are experiencing challenges with increased modification and operational costs due to deteriorating maintainability after migration - Those who want to consider a migration approach that includes maintenance for their own or their clients' environments

- What you can take away from this seminar: Migration is not just about moving systems. The ability to maintain and operate the system continuously after migration significantly impacts subsequent operational costs and system value. This seminar will explain a new migration approach that incorporates AI-driven design document generation, covering concepts from visualizing current assets to migration decisions and maintainability. It will provide concrete hints for future decision-making and improvements for both companies considering migration and those already facing post-migration maintenance challenges.
