7N Advisory’s view on the practical implications of legacy code conversion

CAST software recently conducted an independent assessment of an Asysco mainframe migration for the Ingenium Policy Admin System for an insurance company in the US. In this assessment, ISO metrics were compared for the entire mainframe system, using technologies such as COBOL, CICS, Easytrieve, JCL, DB2, FTP running under IBM z/OS, with the migrated environment, using only native Microsoft technologies such as .NET, C#, SQL Server, Azure DevOps, IIS running on x86 under Microsoft Windows.
In all key areas, such as Security, Reliability, Performance Efficiency, Maintainability, Robustness, Security, and Changeability, metrics improved significantly.
