Job Description               :

Mainframe Decommissioning

Project Background

  • The mainframe is an expensive service for OIT, the agencies and workforce to support and maintain. Applications and processes are aging and the state has lost a number of skilled resources to retirement which were unable to be backfilled. Modernizing applications that utilize the mainframe currently so they are no longer dependent on the mainframe  will reduce risk and expenses for the state.
  • The mainframe’s software and hardware environments were frozen after the successful OS upgrade in 2016. The reason for that is because release notes were not successful in preventing application outages post upgrade.  This left some applications as not functional for a week or more while they were updated to function with the new OS.  That incident caused OIT to pause additional upgrades to the environment for application stability. 
  • The mainframe software could be upgraded but the risk to application environments is too great at this point to have that be a valid option.
  • Identification and migration of all mainframe applications, data transfers, processes(batch jobs, user submitted jobs) and data which need to migrate or be rewritten on another platform has begun. Each agency has the freedom of choosing the best platform solution based on their needs.  That freedom makes it difficult to have all of the mainframe applications retired under the umbrella of one project. 

Problem Statement/Summary of Need:

  • Analysis to date has identified 4 applications and 15 file transfer services remaining on the mainframe. The applications all have active projects to migrate their functionality.  Of the 15 services, 8 have active projects, 1 migration is complete and 6 remain to be analyzed and migrated.  In addition there are a number of seemingly independent jobs running that need to be analyzed and migrated or decommissioned.
  • A vendor will be retained to identify the services data flow, identify associated batch processes and what action those batch processes take, then based on that knowledge identify an approach to move those services and associated processes off of the mainframe and into either a cloud or on premise server environment. Lift and shift is not an acceptable solution as it adds more complexity than benefit.
