Moving SEPM from 2003 to 2008 R2 server

Hi

I'm looking for an "how to" to move my SEPM version 12.1 from a 2003 server to a 2008 R2 server (and reconnect all SEP clients) . I'm using the symantec enbemded DB and i red it wasn't possible to use SEPM replication to proceed. Is it true ? Is it possible to import database backup ?

Regards
