The name change process is largely with your Embassy.
Get it changed on your passport and then go for the residency transfer on the new passport with an affidavit issued by your Embassy.
The residency department will update the old name in all civil information systems, according to the new passport.
The only thing is to make sure bank also updates the information as well.
There will be no change in the civil ID or need to go for finger prints etc.
Rest is about the certificates and other documents, which is specific to the organization issuing the document.
They only ask for name change proof, which is again the passport.
I have gone through this process.
