Migrate to an IBM zEnterprise z196 or z114 server
Description
An IBM zEnterprise System includes a Central Processing Complex (CPC), either the IBM zEnterprise 196 (z196) server or the IBM zEnterprise 114 (z114) server, or both, the zEnterprise BladeCenter Extension (zBX) with its integrated optimizers or select IBM blades, and the zEnterprise Unified Resource Manager (Unified Resource Manager).
The z114 is an entry-level enterprise server with a smaller mainframe footprint than the IBM zEnterprise 196 (z196).
The specific zEnterprise functions including base support that are exploited by z/OS® depend on the z/OS release, Table 1 lists the z/OS functions that are included in the base support for the release. Table 2 lists new functions that can be exploited by the release. For the PTFs that might be required, see Actions you can take before you order a z196 and z114 server.

Table 3 provides more details about this migration action. Use this information to plan your changes to the system.
| Element or feature: | Multiple. |
|---|---|
| When change was introduced: |
|
| Applies to migration from: | z/OS V2R2, z/OS V2R1, and z/OS V1R13. |
| Timing: | Anytime before you introduce a z114 or z196 server into your environment. |
| Is the migration action required? | Yes, if you want to run z/OS V2R2, V2R1, or V1R13 on a z114 or z196 server, or if you want to run a Coupling Facility on a zEnterprise server. If you will run only a Coupling Facility on a z114 or z196 serversystem, then only the sysplex-related actions are relevant. |

Checker for z/OS check, SUP_HiperDispatchCPUConfig, is added to z/OS
V1R12 and available on z/OS V1R11. This check will verify that HiperDispatch
is enabled on a zEnterprise system. For more information, see "HiperDispatch
cache and affinity node changes" in Migration and exploitation considerations for z196 and z114 server functions. Note: The default
of HIPERDISPATCH option in IEAOPTxx parmlib member was changed in
z/OS V1R13 as follows:
