What is Rehosting?
Rehosting lets you take your existing mainframe assets and move them to the cloud or on premise quickly and with minimal risk. Rehosting is a cost effective method of addressing the challenges of maintaining a decades-old mainframe and its applications.

Three mainframe rehosting paths exist with OpenFrame, depending on the maturity level an enterprise plans to reach.
Reducing MIPS:
Enterprises can reduce MIPS consumption by identifying high-consumption or data archiving workloads in their existing environments and offloading these workloads onto less costly open systems or the cloud.
Re-platforming Legacy Apps:
Outdated components can challenge the cost effectiveness of your mainframe and affect the ROI of any major IT upgrade. Rehosting enables you to migrate legacy apps to a new open platform simply and cost effectively.
Replacing the Mainframe:
Sometimes a mainframe has been around for so long that its apps and systems are draining your budget and slowing innovation. In these cases, the mainframe is moved as-is to an open system where it provides services equivalent to those on the mainframe. There are no changes to the underlying business logic of the user interface.
