Best way to migrate requirements from one server/db to another?

I have a client that has requirements in RRC now but must migrate the data in that server to a newly built server.

They can't reuse the existing database or server. They want to migrate the data in their current RRC server to an already existing second server.


I've looked into exporting requirements in either .csv files or REqIF files but in both cases some data will be lost.
For example ReqIF doesn't preserve audit history.


What is the best way to move the requirements from one server to another?
This would be a one time migration and there is no requirement for bi-directional synchronization.


Thanks

Andy
