Pick and choose which mainframe applications to migrate to new environments of your choice with no need to recompile, transcode, or rewrite. By thinking big and starting small you can unlock the value in your applications and lay the foundations for future transformation.

Other applications can continue running on the mainframe, minimizing business disruption and reducing the moving parts. This approach delivers the lowest-risk migration option on the market.

  • Speed up your migration from mainframe to modern systems, in the cloud or on-premises.
  • Reduce migration risk through binary rehosting and incremental migration.
  • Enact meaningful change with zero disruption from day one.

You need to have the courage, and you have to face a change project, but it works. Go for it”
