I've used Mercurial repository with kbfiles but now I have to use pure Mercurial. How to convert repo from kbfiles to pure hg? They are not compatible and seem I will lose all history if I not find the solution.
Do you mean convert the history back to a repository where the big files that were managed by the kbfiles extension are now stored directly in the history?
If so, then use
and you'll get a repository that doesn't require kbfiles.
