How to "transfer" a player from one db version to another

[fosi]

How can I transfer a player from one version of db (24.0) to another (24.3)?
I loaded version 24.0 into the editor, duplicated the player in the editor and saved as a .fmf file. But if I reload it with the 24.3 database I can't see the data. Is this a current limitation of the editor or is there a way and I didn't understand how to do it?

Thank you
