Reverting WPMU (WordPress Multi-Site) To Separate Installations

Hi,

First of all thanks for reading this post. On one of my domain, I installed WP Multi-Site when it was WPMU. I am using it with many sub-domains with single DB.

But now I want to have separate installations for all sub-domains including main site/domain.

Could you please tell me how to achieve it? I don’t want to lose any of my article/file/s

Any help will be highly appreciated. Thanks in anticipation.

P.S. I know basic WordPress things, like installing it from file, DB things. So if you could give me the guidelines, I can follow them.
