Why Was a 40-GB EVS Disk Added to the Target Server During the Migration?

SMS creates and attaches a 40-GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use basis. After the migration is complete, these EVS disks will be released. Do not delete these EVS disks or change their billing mode to yearly/monthly before the migration is complete, or the migration will fail.
