No, that's not what I'm saying. Kallithea does not have conversion built in.

I do not see Łukasz asking about the actual conversion process. I'm sure 
he is aware of the options and trade-offs and can make the conversion 
manually. He is only asking about how he can put a new Git repo in the 
place where the Mercurial repo used to live.


It could be very interesting to develop a hosting solution that was 
completely VCS agnostic. Where the immutable main branches of each 
"repository" were exposed in "all" kinds of VCSs, so users and 
contributors could work and submit changes in any way they want. But I 
doubt anybody wants to invest enough to make that happen ;-)

It would be more simple to integrate external conversion tools so a 
click off a button in Kallithea would make a one-shot conversion to 
another repo format .... with some chosen handling of the fundamental 
VCS differences.
