Migrating data

When you upgrade from Tivoli Netcool/OMNIbus V7.4 (and earlier) to V8.1, you can migrate your existing data manually or use IBM® Installation Manager to automatically migrate your data.

To upgrade your previous version to run in FIPS 140–2 mode, you might need to configure some of your data before or after you upgrade.

When you choose to automatically migrate your data during the upgrade process, migration information is written to the following log file:

NCHOME/omnibus/log/migrate.log

For Linux operating systemFor UNIX operating system

Migrating data on UNIX and Linux

IBM Installation Manager offers the option of automatically migrating data from an existing installation to the upgraded installation. On the data migration panel, you must specify the location of your existing installation, or a backup of that installation, where Installation Manager can find the files to be migrated.

You can also migrate your data manually after upgrading. This requires a backup of your old installation for use with the upgrade script.

To manually migrate data:
  1. Change to the $NCHOME/omnibus/upgrade directory.
  2. Run the following command:

    UPGRADE.SH -old OLD_PATH -new NEW_PATH [-log LOG_FILE_PATH]

    Where OLD_PATH is the location to which you backed up your old installation and NEW_PATH is the new $NCHOME/omnibus location.

    Use the -log option to save the migration information to a log file, where LOG_FILE_PATH is the directory where you want to store the log file. If you do not use the -log option, the details are written to standard output.

For Windows operating system

Migrating data on Windows

On Windows operating systems, only one installation of Tivoli Netcool/OMNIbus is allowed per computer. When Installation Manager starts, it checks for an existing installation. If an existing installation is found, you must remove it before continuing the upgrade.

To remove the existing installation:
  1. Stop all running Tivoli Netcool/OMNIbus processes.
  2. Remove any Tivoli Netcool/OMNIbus services that were manually installed.
  3. Optional: Use one of the following methods to back up your existing data and configuration files:
    1. Run nco_config_save.bat, which is in the ESD .zip file distribution, to back up a predefined set of files.
    2. Manually copy the contents of the existing %NCHOME% directory to a backup location.
  4. Remove all installed probes and gateways.
  5. Run %NCHOME%\_uninst\OMNIbus\uninstall.exe -i console.

After the old installation of Tivoli Netcool/OMNIbus is removed, you can continue with the upgrade.

If you backed up your old installation, you can migrate your existing data and configuration. In the Installation Manager data migration panel, enter the location of your backup. Alternatively, you can manually copy your data and configuration files to the new installation.
