How to implement data transfer? I don't know if this is the correct name.

For example, after a database is used for a period of time, I want to transfer some business data to a historical database to relieve the pressure on the current database. For example, there are many tables in my database, including order tables and order lists. After one year, I just want to transfer the data from the order table and order list to a historical database half a year ago, in normal times, only the current database is queried. In special cases, the two databases are comprehensively queried. How can this idea be implemented.

How do you deal with the accumulated historical data of related services?
