Subject How to copy the data within FDB's without changing the schema

I am trying to copy the data in an existing FDB to another FDB.

The database schema varies for both the databases.

Please suggest me any tool which copies the data into the destination
FDB, with out changing the schema.

Also consider if the source FDB has some data in the columns.

If that particular columns doesnot exist in the destination FDB, then
what will be the behavior of the tool?

Best regards,
