Installing z/Server as an Upgrade

Enterprise Developer 2.3 requires an installation of z/Server version 2.3 (V2R3) or higher.

Before upgrading an existing installation of z/Server of a version earlier than version 2.3, Micro Focus recommends that you install z/Server 2.3 on separate ports, and test this with AWM in Enterprise Developer 2.3:

  1. Install z/Server 2.3 on ports separate from your current installation of z/Server. Keep the existing z/Server as the productive server installation.
  2. Install Enterprise Developer 2.3 and ensure that all server connections point to the z/Server 2.3 installation.
  3. Test your remote AWM models against the server. For example:
    • Test whether you expanding your defined data set filters works in MVS Explorer.
    • Try to duplicate and delete a member in a PO data set.
    • Edit and save a sequential MVS file or a member of a PO data set from the MVS Explorer.
  4. After all tests have successfully passed, roll out Enterprise Developer 2.3 across your organization.

    AWM in all installations should point to the z/Server 2.3 installation.

  5. When all Enterprise Developer installations have been upgraded successfully, the tasks started by the earlier version of z/Server can be deactivated or uninstalled.
