Hi there im just windering is there white paper on how up migrate from Server 2003 - SBS 2003 ?

According to the SBS 2003 documentation on the microsoft site, if you're running Server 2003 standard edition, you can "upgrade" to SBS 2003. It says nothing about other versions, but because 2003 standard was specifically pointed out, I'd bet that if you were running 2003 enterprise or 2003 web, it'd not work and you'd need to do a clean install. Note that 2003 standard to 2003 SBS says it should work, it isn't a supported configuration, so if you were to contact Microsoft support for assistance it probably would not be forthcoming. Just a heads-up.
