# Validation / Workflow Rules ### Validation Rules: Overview Validation rules ensure that data entered into a Salesforce record meets specific criteria before saving. These rules are composed of a formula or expression that evaluates one or more fields and returns **True** (invalid) or **False** (valid). When a rule returns True, a specified error message is shown to the user. *** #### Disable Validation Rules When the **Disable validation rules** checkbox is selected during a DataLoader job, all validation rules associated with the relevant Salesforce objects are temporarily deactivated. Data is then migrated to the destination sandbox. Once migration is complete, the validation rules are reactivated automatically.

Starting with ARM version 20.1, all validation rules are listed in the ARM UI. Users may review and manually re-enable rules as needed.

*** ### Workflow Rules: Overview Workflow rules automate standard processes and procedures. They typically follow an **if/then** logic model—triggering actions when specified conditions are met. *** #### Disable Workflow Rules Selecting the **Disable workflow rules** checkbox during the DataLoader job will deactivate all applicable Salesforce workflow rules during data migration. After the migration is complete, ARM reactivates the workflows.
