 Import-based assessments are assessments created with machines that are imported into Azure Migrate using a CSV file. Only four fields are mandatory to import: Server name, cores, memory, and operating system. Here are some things to note: 
  - The readiness criteria is less stringent in import-based assessments on the boot type parameter. If the boot type isn't provided, it is assumed the machine has BIOS boot type and the machine is not marked as **Conditionally Ready**. In assessments with discovery source as appliance, the readiness is marked as **Conditionally Ready** if the boot type is missing. This difference in readiness calculation is because users may not have all information on the machines in the early stages of migration planning when import-based assessments are done. 
- - Performance-based import assessments use the utilization value provided by the user for right-sizing calculations. In assessments with discovery source as appliance, the chosen percentile value is picked from the performance data collected by the appliance.
+ - Performance-based import assessments use the utilization value provided by the user for right-sizing calculations. Since the utilization value is provided by the user, the **Performance history** and **Percentile utilization** options are disabled in the assessment properties. In assessments with discovery source as appliance, the chosen percentile value is picked from the performance data collected by the appliance.
