The zEC12 and zBC12 are the newest IBM System z servers and distinct from the earlier zEnterprise and other servers. In this publication the IBM zEnterprise EC12 server is referred to as the model zEC12 server and the IBM zEnterprise BC12 server is referred to as the model zBC12 server.
The specific zEC12 and zBC12 functions including base support that are exploited by z/OS depend on the z/OS release. Availability and other restrictions are noted in the Notes column. PTFs might be required for many of these functions. See Actions you can take before you order a zEC12 or zBC12 server for information about finding the appropriate PTFs.

| Element or feature: | Multiple. |
| When change was introduced: |
|
| Applies to migration from: | z/OS V2R1, z/OS V1R13 and z/OS V1R12. |
| Timing: | Anytime before you introduce a zEC12 or zBC12 server into your environment. |
| Is the migration action required? | Yes, if you want to run z/OS V2R1, z/OS V1R13 and V1R12 on a zEC12 or zBC12 server, or if you want to run a Coupling Facility on a zEC12 or zBC12 server. If you will run only a Coupling Facility on a zEC12 or zBC12 system, then only the sysplex-related actions are relevant. |

| Restrictions: | See Restrictions for a zEC12 or zBC12 server. |
| System impacts: | None. |
| Related IBM Health Checker for z/OS check: | IBM Health Checker for z/OS check, SUP_HiperDispatchCPUConfig, is added to z/OS V1R12 with APAR OA30476. This check will verify that HiperDispatch is enabled on a z196 or later system. |
Steps to take: Follow the General recommendations and considerations for a zEC12 and zBC12 server, adhere to the Restrictions for a zEC12 or zBC12 server, and perform the tasks described in the following topics.
