Rolling back a failed upgrade

If your upgrade fails or the product does not work after the upgrade is completed, you can rollback the failed upgrade to an earlier version of the product. An upgrade failure might occur in one of the following scenarios:

• If you made any changes to the Configuration Database.
• If the ports used for the upgrade are unavailable.
• If you do not have sufficient permissions to perform the installation. For more information, see Preparing for installation.

When you perform an upgrade, the following files are automatically backed up at %BMC_ITDA_HOME%\Upgrade_Backup_version:

For more information, see Modifying the configuration files.

Note: The product does not automatically back up the indexed data, therefore you need to manually create a back up.

To rollback a failed upgrade to an earlier version

1. Create a back up of the indexed data at an appropriate location.
2. Uninstall the product to which you upgraded. For more information, see Uninstalling.
3. Install the previous version of the product.
   Note: During installation, ensure that the product services are not started immediately after the installation is complete.

4. After the installation is complete, copy the backed up files to the appropriate locations:

   From	To
   %BMC_ITDA_HOME%\Upgrade_Backup_version\conf	%BMC_ITDA_HOME%\conf
   %BMC_ITDA_HOME%\Upgrade_Backup_version\custom	%BMC_ITDA_HOME%\custom
   %BMC_ITDA_HOME%\Upgrade_Backup_version\station\collection	%BMC_ITDA_HOME%\station\collection
   %BMC_ITDA_HOME%\Upgrade_Backup_version\data\configdb	%BMC_ITDA_HOME%\data\configdb
   %BMC_ITDA_HOME%\Upgrade_Backup_version\data\indexer	%BMC_ITDA_HOME%\tomcat\webapps

5. Start the product services. For more information, see Starting or stopping product services.
6. Start the product. For more information, see Accessing the console.
   The product is restored to the earlier version along with the indexed data, configuration data, and any customizations you must have made.
