1. A method for copying data from a source server to a target server, wherein said data is associated with a metadata having a set of properties, the method comprising: mapping the metadata to a metadata structure of the target server, where the mapping comprises determining common names for properties being comprised in the metadata, wherein a common name defines a general concept for a property in question; determining if the metadata structure of the target server comprises corresponding properties having the same common names; and if so, copying—together with the data—such properties of the metadata that have matching common names in the metadata structure of the target server.
