Why Source Code Dependency is a Challenge for Mainframe Workload Re-hosting

Reducing reliance on source code enables migration to Linux, x86 and the cloud

Mark Cresswell, CEO of LzLabs, discusses how the traditional approach to mainframe re-hosting - involving recompilation of source code - is fraught with issues that often render projects costly and unsuccessful. He  summarises the benefits of an alternative, software-defined approach that enables migration of mainframe workload and data to open systems, without recompilation.

The key topics covered include: 

  • Unravelling the 'Gordian Knot' of application interdependencies 
  • Encoding issues faced when moving from mainframe to x86
  • Overcoming the challenge of data processing when migrating from mainframe database to PostgreSQL
