Migrating change requests to a central server

If you installed IBM® Rational® Change in Central Server mode, you can immediately start submitting new CRs. To see any pre-existing CRs (CRs that were created in a development database before Central Server mode was being used), you must migrate them into your central CR database.

About this task

The migration process can be lengthy. The CR migrate process can take hours, or even days for large databases. Any DCM packages received while CR migrate is in progress can extend the migration time.

Users can continue to use the product during a CR migrate. Both the central CR database and the development database can remain enabled. As CRs are migrated into the central CR database, they are available immediately for users to view and edit. The newest CRs are transferred first.

Procedure

To migrate change requests to a central server:

  1. Start an Admin session on the Rational Change server that has the database that you want to migrate.
  2. On the Action Panel, click System Administration.
  3. On the Server tab, click Properties.
  4. At the bottom of the Properties tab, click CR Migrate.
  5. Select the database containing the CRs you want to migrate.
  6. Specify whether you want to be notified when CR migrate is complete.

    Your central server must be configured to send mail through an SMTP server to use this feature. If you do, verify that your email address is correct.

  7. Click Migrate.

    The CR Migrate window shows the progress of the migration. Closing the window does not stop the migration. You can open and close the window to check on the progress.

    If you decide to stop the migration, click Stop. You can continue the migration later by migrating the same database again. The migration resumes from where it was stopped. If a migration failed because of network problems or other errors, restart and continue it from where the problem occurred.

    After the CR migrate has finished, optimize your central CR database by running the ccmdb update_statistics command. You can also run this command in the middle of the CR migration process when you suspect the migration is getting slower. You might improve performance when you run this command.
