Siebel Database Upgrade Guide > Siebel Database Upgrade Planning > About Single-Step Repository UpgradePrior to the release of 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. Going forward from the release of 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. Table 12 describes examples of different methods for upgrades to the current release, including upgrade paths that use the single-step repository upgrade. The repository for the current release is SIA in all cases. For more information, see Supported Upgrade Paths for Siebel CRM Version 16.0. Data Model Changes for Single-Step Repository UpgradeDue to data model changes around Address objects between the SEA and SIA repositories, the migration from the SEA repository to the SIA repository will result in some SEA objects being made obsolete. You must reconfigure all Address-related business components that are in use. In general, the same development upgrade process needs to be applied for the SEA to SIA migration on the same version. Migrating from SEA to SIA on the same version requires less effort then upgrading from one version to a higher version. For more information, see Migrating Address Data After a Direct SEA to SIA Upgrade. |
