Determining Your Repository Version

Use the following procedure to determine your repository version.

To determine your repository version

Connect to your development database using an appropriate database-specific tool, such as Oracle's SQL*Plus.
Run the following query command to determine the repository version:
```
SELECT APP_VER FROM <tableowner>.S_APP_VER
```
Note: Your repository version may not match your binary version. For example, customers on Siebel CRM 15.5 who have not run an Incremental Repository Merge from Siebel CRM 15.0 will still be on repository version 15.0.

After you determine your repository version, then decide which ancestor repository to use based on that version using the information in the following table. The ancestor repository relevant to your upgrade is the Siebel repository that was shipped with the Siebel CRM release that you are upgrading from. It contains none of your customizations.

Note: Neither an Incremental Repository Merge nor a Database Upgrade is required for Siebel CRM 17.0 or later. For more information on installing Siebel CRM monthly updates, see the roadmap for installing Siebel CRM 22.x Update for an existing installation of Siebel CRM 17.x or later in Siebel Installation Guide.
