Ielts passport number change and bifurcation of full name into sur name and given name

[naseer shezan]

I recently got my new passport . In that I have added surname (bifurcation of full name) bcoz it is very necessary in western countries.
I wrote ielts in that I don't have surname. So can I proceed with visa filing coz passport number is changed and I have add surname in that and my new passport has a reference of old passport.
Can anyone of you guys help me in this regards .
