2.2.2 Overwriting or upgrading an existing instance

To upgrade an existing instance of CPA:

1. As a member of the Administrators group, log in to the host on which you want to install CPA.

2. Exit all programs.

   Stop the running services and close the Job Design View, if any.

3. Insert the CPA media and start the installation.

   Follow the instructions from the Hitachi integrated installer to upgrade or overwrite the existing instance.

Important

• If an unexpected error occurs while you overwrite or upgrade an existing instance, the data of the instance might be lost and no longer be restored. Make a backup copy of the data folder before you can start overwriting or upgrading.

• If you overwrite or upgrade the existing instance, the properties for the job execution service and message communication service are reset to the default values. If you have customized the properties for these services, customize them again.

  For details on the service properties, see Table 2-1 Default values for installation settings.
