Select the critical files from the old computer and migrate the same to new computer system and check the result.
The entire data was identified by its File Number, format, and Volume. The critical text and values were underlined.
After migration, all documents were checked for correctness by designated persons. There were no change in formatting and Volume. The critical values, graphs were not affected by any means. The transfer was complete in respect of raw data, meta data, and processed data. The data can be accurately archived and processed on new system and the results are within the limits as specified during the original computation.
