Recommended migration steps for a z196 and z114 server

This topic suggests the steps for migrating your same z/OS® release level from your current server to a zEnterprise server. The steps are based on the assumption that you want to minimize the amount of change (and therefore risk) and the amount of work required to perform the migration.

The migration steps follow:
  1. If necessary, migrate to an STP-only or Mixed-CTN timing network.
  2. Ensure that you have installed the z196, z114, z10™ EC (or z10 BC), and z9® EC (or z9 BC) required service, as indicated in the respective PSP buckets. See "Install the necessary z/OS service, as indicated in PSP buckets" in Actions you can take before you order a z196 and z114 server for information about how to identify, acquire, and install any missing required service.
  3. Ensure you have the required service, and any required ICSF web deliverable installed for the cryptographic functions that you have decided to use.
  4. Upgrade your hardware to zEnterprise system. If necessary convert to InfiniBand Coupling Links from ICB-4 links.
  5. Update configuration setting to exploit zEnterprise functions.
