Join multiple subrepos into one and preserve history in Mercurial

Question

Currently I have project consisting of multiple repositories, e.g.:

+---Project (main repo)
    +---Core (subrepo)
    +---Web          


        

Answer 1

First guess : Perhaps by using the convert extension with a filemap ?

Another try :

• Pull all your repos into the same repo, you will have different heads for the "default" branch
• Then for each head
  • Update to this head
  • Move the files (hg move) into the right directory
• Merge all the "default" heads together

Edit : added more details, and another try
