# Migration Setup Tab

The Migration Setup tab contains tools which are useful when migrating data to a Salesforce instance unrelated to the Salesforce instance used to create the CopyStorm backup.

This is useful when trying to perform tasks like:

* Mapping Users in a CopyStorm backup to users in the target Salesforce. In this case, Salesforce Ids will not work due to being unique to a Production or Sandbox instance’s setup. The Record Mapping Rule tool on this page supports implementing and establishing rules that CopyStorm/Restore will use to map users from the CopyStorm backup to users in the target Salesforce.
* Maintaining Salesforce Ids in a CopyStorm backup when creating data in the target Salesforce. In this case, Salesforce Ids will be regenerated when data is inserted. The Original Record Id Rule tool on this page supports creating and populating a new custom field to maintain the source CopyStorm database Id values.
