Unplanned Migration Prevention

When you install enterprise to MPP migration firmware COP files, the firmware files are available for use to specify as load name. You can then configure to retain the default Load Information value of the phone. As a result all the phones of the same model do not start migration process unintentionally. It allows you to change the default load manually.
