About Siebel Repositories
Prior to the Siebel CRM version 8.1.1, two Siebel repositories supported Siebel applications: Siebel Business Applications (SEA) repository and Siebel Industry Applications (SIA) repository. Deploying applications from outside either group was not possible through a direct, single-step upgrade process.
Since Siebel CRM version 8.1.1, a single repository is supported (SIA) and an upgrade process is available that enables a direct, single-step upgrade from SEA to SIA repositories. After running database configuration utilities, you can perform direct upgrades from an SEA deployment to a higher version SIA repository through a single-step process, for certain supported upgrade paths. For example, you can directly upgrade to the current release from Siebel CRM version 7.8 SEA or SIA, or from version 8.0 SEA or SIA, using a single-step upgrade method.
