Exclude a table from cloning

Exclude a table to create an empty but usable table on the target instance.

About this task

The System Clone > Exclude Tables module lists the tables that are not copied during a system clone. By default, the system excludes tables for logging, auditing, notifications, workflow contexts, and license usage.

Note: Excluded workflow context data includes records stored in the wf_context table, and in related tables with names starting with a prefix of wf_. This also includes the workflow scheduler table. This prevents occurrence of workflow timer syncing issues that might take place due to the length of the cloning process if workflow contexts were included.

The system cannot exclude tables that extend the Task table and are also flattened into it as part of the table per hierarchy extension model. Since these extended tables are actually part of the same physical database table, the system clones the data when it clones the Task table. You can exclude tables that extend the Task table under two conditions. Either the system stores the tables in their own physical tables as part of the table per class extension model, or you exclude the Task table itself.

To preserve the existing data on the target instance, see Create a data preserver. Data on tables that reference the table, such as business rules, is not excluded.


  1. Navigate to System Clone > Exclude Tables.
  2. Click New.
  3. Enter the table Name.
    Entering a parent table results in the clone process also excluding its child tables. For example, excluding the Task table would also exclude the Change, Incident, and Problem tables.
  4. Click Submit.
