Getting links to a new site without 301 redirect

[rishi02]

I have been writing the blog almost for two years. Now I want to publish a brand new blog with some vast niche (with the present niche in it). For some technical difficulties I am unable to 301 redirect them.

Is there any way to transfer those backlinks to the posts in the new site? I willing be publishing the old posts in more upgraded way in the new site.

How do you have got the those backlinks? Were they built by you or someone else.

They are 99% from guest posts done by me.

Now the most reasonable thing to do is to contact those webmasters manually and make them change the links.

But that process is a long term one. I mean people usually don't even give response because there is nothing in it for them.
