This guidance for those involved in Drug application (INDs, ANDAs) provides guidance for methods validation. It mentions software platform changes as a possible reason for partial validation:
“Partial validations are modifications of already validated bioanalytical methods. Partial validation can range from as little as one intra-assay accuracy and precision determination to a nearly full validation. Typical bioanalytical method changes that fall into this category include, but are not limited to:
Changes in instruments and/or software platforms”.
