Preparing to Migrate the Repository

This task is a step in Process of Migrating a Repository.

In this topic, you prepare to migrate the repository.

To prepare to migrate the repository

1. Make sure you complete testing.

   You must verify that any customizations you make work correctly and that they meet your business requirements.

2. Make sure the target database configuration meets the database requirements described in the Siebel Installation Guide for the operating system you are using and in Siebel System Requirements and Supported Platforms on Oracle Technology Network.
3. Check in all projects in the source database and the target database.

   If a project is checked out, and if you migrate a database, then the migration works but Siebel CRM does not lock the project in the target database. For more information, see Checking Out and Checking In Projects and Objects.

4. If your environment includes Remote users, then make sure all these users do a full synchronization.
5. Do a full backup of the target database.
6. Delete old repositories from the target database.

   For more information, see Deleting a Repository.

7. Update database statistics, if necessary.
8. Export the source repository to a file.

   It is recommended that you use the Database Configuration Wizard to export the source repository to a file. You will use this file later during a migration. For more information, see Exporting a Repository.

   You can also migrate directly from the source database. If you do this, then you do not need to export the source repository to a file.

9. If you do not need to minimize downtime during a migration, then you must stop all Siebel Server tasks and disconnect all database access until the migration finishes. This downtime occurs in the Siebel Enterprise where the target repository resides.
