z/OS Upgrade and Installation
Plan your upgrade to IBM z/OS V2R5
IBM® z/OS® V2R5 is designed to enable and drive innovative development to support new hybrid cloud and AI business applications. This new release offers easier access and a simplified experience to next-generation systems operators and developers, while providing optimal usage of IBM Z computing power and resources for scale, security, and business continuity.
For more information, see IBM United States Software Announcement 221-057.
A better z/OS upgrade experience with z/OSMF workflows
Using a z/OSMF workflow, you can perform a z/OS upgrade as an interactive, step-by-step process. The z/OS Upgrade Workflow uses the latest functions in z/OSMF to provide a smooth upgrade experience.
As of z/OS V2R4, IBM® no longer provides a z/OS Migration publication. Since z/OS V2R2, the preferred method for learning about upgrade actions has been the z/OS Upgrade Workflow. Discovering, performing, and verifying many upgrade actions through the z/OSMF Workflows task instead of a more traditional book format allows for a tailored and specific upgrade path that is associated with a particular system. Beginning with z/OS V2R4, IBM provides upgrade tasks in a z/OSMF workflow.
z/OS V2R5 Upgrade Workflow
The z/OS V2R5 Upgrade Workflow provides the steps for upgrading your system to z/OS V2R5. Two workflows are provided. Depending on whether you are upgrading from z/OS V2R4 or z/OS V2R3, select the workflow that applies to your upgrade path and open it in z/OSMF to begin the upgrade process. In the workflow, discovery functions run automatically to further streamline your upgrade experience. Only the upgrade actions that apply to your particular system are identified in the z/OSMF user interface (UI).
The z/OS V2R5 Upgrade Workflow can be run on z/OS releases V2R3, V2R4, and V2R5.
IBM provides the upgrade workflows as part of the z/OS product. Updates and fixes for the upgrade workflows are delivered through the standard z/OS service process. To obtain the latest PTFs for the z/OS V2R5 Upgrade Workflow, run the SMP/E REPORT MISSINGFIX command on your z/OS systems and specify a FIXCAT value of "IBM.Coexistence.z/OS.V2R5".
After the PTFs are installed, you can create the workflow on your z/OS system.
For more information, see z/OS V2R5 Upgrade Workflow.
IBM z16 Upgrade Workflow
The IBM z16™ Upgrade Workflow contains the upgrade steps for the IBM z16™ server. These steps include considerations, restrictions, and actions to take before and after you receive your server, and a checklist of items that are planned to be discontinued on future servers.
The IBM z16 Upgrade Workflow can be run on z/OS releases V2R3, V2R4, and V2R5.
The z/OS z16 Upgrade Workflow is provided and maintained with z/OS PTFs that are assigned the following SMP/E fix category (FIXCAT): "IBM.Device.Server.z16-3931.RequiredService."
After the PTFs are installed, you can create the workflow on your z/OS system.
For more information, see IBM z16 Upgrade Workflow.
