# Default Device Drivers

It is possible to customize device drivers in IONE 6.0.1PME 7.2.2, for example, by adding software logging. This is typically done through the Modbus Device Type Editor (MDI). The customizations are stored in the ION and XML translator files under `...\config\translators`.

To recreate default device driver customizations:

1. Navigate to `...\Power Monitoring Expert\CM Migration Files`.
2. In the MDI, determine whether the files copied to the CM Migration Files folder were customized.
3. Manually recreate any desired customizations on the target system by customizing the PME 8.2 version of the driver.

Note: Since this process may need to be followed for any future PME upgrades, note the customizations for future upgrades.
