The following procedure outlines the main steps of migrating from a SLES 10 TASM-licensed system to a SLES 11 system licensed for TASM or IWM. Before performing this task, be sure to review General Upgrade Considerations and License- and Platform-Dependent Upgrade Considerations.

  1. Ensure that the version of Teradata Database on the source system meets the requirements for migration based on the database to be installed on the destination system and whether you plan to use the Pre-Migration Tool.
  2. If the source system includes rule sets that you have not used and do not intend to use in the future, delete them to speed the process of workload migration.
  3. [Optional] To refine the otherwise automatic results of converting workloads for use in SLES 11, use the Pre-Migration Tool on the source system well in advance of the operating system upgrade.
    If you do not use the tool, or if you accept all default settings when using the tool, workloads as automatically migrated may not meet your priority-scheduling goals in SLES 11.
  4. Back up the source system data, including the TDWM database. This database encompasses the tdwm.premigrate table, which contains any adjustments to workloads that resulted from use of the Pre-Migration Tool.
  5. On the destination system, install SLES 11.
  6. On the destination system, install a version of Teradata Database that is supported on SLES 11 and meets or exceeds the minimum requirements of the hardware.
  7. On the destination system, restore the TDWM database.
  8. On the destination system, run the post_data_restore script. The post_data_restore script executes the TDWMDIP program, which converts SLES 10 performance groups or workloads, as applicable, to SLES 11-compatible workloads based on a default processing scheme or the directives in the tdwm.premigrate table within the TDWM database, if such directives exist.
  9. Bring the destination system to the Logons Enabled state.
  10. Use the Workload Designer portlet in Teradata Viewpoint to refine workload settings as necessary.
