Recovery From A Failed Upgrade

This section details steps to restore an Attunity installation that was part of an ODM install in the event that the upgrade failed to preserve existing configurations.

After upgrading Connect Server to version 5.3 or 5.3.2, testing the data sources may fail or produce unexpected results. Data sources that use advanced features from Attunity Server version 4.8 that are not included in version 5.3 may result in errors or missing metadata. To fix this problem, you can downgrade from Attunity version 5.3 to version 4.8. It is recommended that the following procedure to restore to the previous configuration be used only as a last resort.
  1. Stop the daemon.
    1. Right-click My Computer and select Manage.
    2. Expand the Services and Applications section and select Services.
    3. Right-click Attunity Server, and select Stop
  2. Uninstall the Server that did not upgrade correctly. Ensure that all directories and files have been removed and, if required, delete any remaining directories and files.
  3. Reinstall Attunity Server version 4.8 to the location used prior to the upgrade.
  4. Replace the <NAVROOT>/Def directory with the new directory that was backed up during the upgrade process. This backup file is located in C:\Program Files\Attunity\AIS_BackUp on a Windows machine, and on $PSTHOME/ODM/AIS_BackUp on UNIX.
  5. Start the IRPCD daemon.
    1. Right-click My Computer and select Manage.
    2. Expand the Services and Applications section and select Services.
    3. Right-click Attunity Server, and select Start.
Attunity Server version 4.8 is now installed with the previous configuration. If the previous configuration continues to have problems contact IBM Software Support.
