Rather than letting the View Composer installer upgrade the database when a schema update is required, you can manually upgrade the database. You can use the SviConfig utility when you must observe the upgrade process more closely or when upgrade tasks must be distributed to IT administrators with different responsibilities.

When you upgrade View Composer to a version with an updated database schema, an installer prompt asks if you want the wizard to upgrade the database. If you choose not to use the installer wizard, you must use the SviConfig utility to upgrade the database and migrate the existing data.

Using the SviConfig command-line utility has the following advantages:

This utility returns result codes and creates a log of the database upgrade to simplify troubleshooting if the upgrade fails.

You can separate the upgrade tasks. A vSphere or View administrator can run the View Composer installer to upgrade the software. A database administrator (DBA) can use SviConfig to upgrade the View Composer database.

The software upgrade and the database upgrade can occur during different maintenance windows. For example, your site might run database-maintenance operations on weekends only, whereas software-maintenance tasks can occur during the week.
