Reassigning Cases to Territories

You can reassign existing cases to your case territories, which is useful when you're restructuring your case territories.

Go to Setup > Support > Territory Reassignment.
On the Criteria subtab, select criteria that will return a list of the cases you want to reassign.

The reassignment is determined using your current set of assignment rules and territories.
On the Results subtab, you can customize what information displays in the list of found cases.
To use the Audience subtab, click the Public box above the subtabs. Select who should be able to use this update again with your criteria. You must save the update for it to be available to this audience.

If you check the Public box but don't select audience members, the update is available to all users in your account by default.
Click Preview.
In the Apply column, clear the box next to any cases you don't want to reassign.
Click Perform Update to reassign the cases, or click Save to reassign the cases and save the update for later use.

Now, these cases are reassigned according to your case territories in priority order.

To access a saved reassignment update, go to Lists > Mass Update > Saved Mass Updates.
