Mainframe Modernization
Mainframe systems still hold strategic importance for many organizations, particularly in the financial, industrial, and public administration sectors. Since they have supported business operations for many years, modernization activities are required to make them more manageable and aligned with the operational paradigms of modern IT departments.
In this context, Hogwart supports clients in the modernization and integration of processes and systems involving the mainframe.
Services:
- Projects to adapt application Change Management (ALM) processes and systems, redesigning them as needed and replacing tools (from mainframe to mainframe, or mainframe to open environments);
- Application portfolio analysis with the aim of decommissioning outdated tools and languages in favor of more modern and high-performing solutions;
- Migrations of core areas of the application portfolio (languages and databases), supported by proprietary automatic conversion engines;
- Replacement and modernization of mainframe management systems, maintaining mainframe-based tools or transitioning to distributed products.
Examples of system change and application migration:
Changing the Change Management tool, either staying within the mainframe environment or moving to an open system:
- Endevor → ChangeMan
- Custom mainframe-based tool → ChangeMan
- ChangeMan → open system (including rehosting projects)
Migrations of application objects between systems are performed using proprietary automated tools developed and refined over the years.
Examples of migrations between programming languages or databases using proprietary conversion engines:
- Easytrieve → Cobol
- Cobol → PL-SQL
- DB2 → Oracle (in rehosting projects)
- JCL → Shell
- Bull Cobol → Micro Focus Cobol (in rehosting projects)
- Bull TP → Tuxedo (in rehosting projects)
- DMIV → DB2 and TPFORM → IBM Forms (in Bull mainframe to IBM AIX migrations)
Products:
- Mainframe ALM (ChangeMan)
- Mainframe ALM (AMI DevX Code Pipeline)
- Open and Mainframe ALM (IBM IDz EE – DBB)
- Open and Mainframe ALM (IKAN ALM)
