Well I would suggest you to redirect the old URL to the new one, in this way all backlinks will redirect to the new one and just update the new changes in the webmaster.
This will not only redirect your backlinks but it will also pass the PR to the new webpage.
Thank you for the reply and for your suggestion. Is it 100% that all my backlinks will back after the webmaster redirect my site?
