In exporting and importing content just import last version!

[sara]

Hi,
When I export a space and import to the other space it just import the LAST version of the contents.
How can I export all versions of contents from a space to another one?
I have read http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Fconcepts%2Fcuh-content...
Thanks

You would need to write your own import / export.
