Final answer:
Data precision and data analytics are the two most likely reasons for sanitizing client data during the migration process from a legacy ERP system to a cloud-based ERP tool.
Step-by-step explanation:
The MOST likely reason for the need to sanitize the client data when migrating between a legacy ERP system and a cloud-based ERP tool using a global PaaS provider is to ensure data precision and compliance with regulatory requirements. Data precision refers to the accuracy and correctness of the data, and sanitization helps remove any duplicate or inaccurate data, ensuring the data is precise and reliable. Additionally, sanitization also helps in maintaining data analytics accuracy. By removing duplicates and inconsistencies from the data, organizations can obtain more accurate and meaningful insights from the data analysis process. This is particularly important when migrating data between different systems, as the data needs to be clean and consistent for effective analysis.
