It is possible to purge that data through a 3rd party that charges for that type of service. 
The Sage 50 product does not have the capability to do what your asking. 
I can give you some ideas of what is possible. Please pm me.

No, it is not recommended to purge old records containing serialized stock items in Sage 50 2023 as it can result in the loss of important information and affect the accuracy of your inventory records. Serialized items should be tracked throughout their entire life cycle to ensure proper inventory management, warranty and service tracking, and financial reporting. Instead, consider archiving old records to free up space in your active database while still retaining access to the information when needed.
