Easy switch from Mercurial to Git

June 29th, 2010 by Jérôme Leave a reply »

For a project I am currently working I needed to switch from Mercurial to Git.

I used the method described below, that is really trivial and it works just fine.

Download  fast-export and extract it wherever you want.

Run the following commands :

mkdir git.migration && cd !$ && git init
/path/to/fast-export/hg-fast-export.sh -r /path/to/your/mercurial/repository

And wait for a few minutes/seconds, depending on the size of your repository. In the end of the process you should get a result like :

git-fast-import statistics:
---------------------------------------------------------------------
Alloc'd objects:      10000
Total objects:         5426 (       566 duplicates                  )

pack_report: getpagesize()            =       4096
pack_report: core.packedGitWindowSize =   33554432
pack_report: core.packedGitLimit      =  268435456
pack_report: pack_used_ctr            =          1
pack_report: pack_mmap_calls          =          1
pack_report: pack_open_windows        =          1 /          1
pack_report: pack_mapped              =    7542871 /    7542871
---------------------------------------------------------------------

Now run :

git checkout

Done.

‘Hope that helps :)
