Migrate DMS files from DMS_C1_ST to Content Server

Today we are using DMS documents setted KPRO and keeping attachements at DMS_C1_ST proposed by standard SAP.

Now, we need change documents repository to Content Server HTTP, until now it´s OK. The doubt is, how migrate the old files, that had already been loaded in DMS_C1_ST, to the new Content Server ??? And after this, when we display a document in CV03N we´ll see the attachments ok in the new repository ???

There is a way to do this ??? If someone knows, please let me know.

Thanks by the help.
