How to split & insert transactions

Hi Experts,

I have a requirement that in my Table I have some data that needs to be splitted by date & hours. Can anyone help me by providing the best way to achieve this please. 

Consider the table - MyTable has fields From date, To date, From time, To Time & hours. 

Consider the record - From Date           To Date              From Time        To Time            Hours

                                   23/05/2021        25/05/2021           10:00 am         12:00 am             38

I need to split above record into two records 14 hours for 23/05/2021 & 24 hours for 24/05/2021. There are around 10,000 records to be splitted in this way, what will be the best way to get it done ? AOT job, Class or SQL. Can any one help with the best logic also please.

Thanks in advance.
