Recommended migration steps for a System z10 server

This topic suggests the steps for migrating your same z/OS® release level from your current server to a System z10™ 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.

If your current z/OS release is V1R12, follow these steps:

  1. Install the service in the following PSP buckets:
    • The z10 PSP bucket:
      • For the z10 EC: upgrade 2097DEVICE, subset 2097/ZOS
      • For the z10 BC: upgrade 2098DEVICE, subset 2098/ZOS
    • The z9® EC PSP bucket: upgrade 2094DEVICE, subset 2094/ZOS (if not already on a z9 EC or z9 BC)

If your current z/OS release is V1R13, follow these steps:

  1. Install the service in the following PSP buckets:
    • The z10 PSP bucket:
      • For the z10 EC: upgrade 2097DEVICE, subset 2097/ZOS
      • For the z10 BC: upgrade 2098DEVICE, subset 2098/ZOS
    • The z9 EC PSP bucket: upgrade 2094DEVICE, subset 2094/ZOS (if not already on a z9 EC or z9 BC)

If your current z/OS release is V2R1, follow these steps:

  1. Install the service in the following PSP buckets:
    • The z10 PSP bucket:
      • For the z10 EC: upgrade 2097DEVICE, subset 2097/ZOS
      • For the z10 BC: upgrade 2098DEVICE, subset 2098/ZOS
    • The z9 EC PSP bucket: upgrade 2094DEVICE, subset 2094/ZOS (if not already on a z9 EC or z9 BC)

Tip for locating the correct service: To simplify finding the appropriate PSP bucket and identifying which PTFs listed in the PSP bucket need to be installed on your system, use the SMP/E REPORT MISSINGFIX command in conjunction with the FIXCAT type of HOLDDATA, as follows:

  1. Acquire and RECEIVE the latest HOLDDATA onto your pre-z/OS V2R1 systems. Use your normal service acquisition portals or download the HOLDDATA directly from http://service.software.ibm.com/holdata/390holddata.html. Ensure you use the FULL file (last 730 days) to receive the FIXCAT HOLDDATA, as the other files do not contain FIXCAT HOLDDATA.
  2. Run the SMP/E REPORT MISSINGFIX command on your pre-z/OS V21R1 systems and specify a Fix Category (FIXCAT) value of "IBM®.Device.Server.z10-BC-2098" or "IBM.Device.Server.z10-EC-2097". The report will identify any missing coexistence and fallback PTFs for that system. For complete information about the REPORT MISSINGFIX command, see SMP/E for z/OS Commands.
  3. Periodically, you might want to acquire the latest HOLDDATA and rerun the REPORT MISSINGFIX command to find out if there are any new coexistence and fallback PTFs.
