Comment (by pmav99):

 I don't have any experience with SVN to GIT conversions, but shouldn't
 there be 70k+ commits?

 I did run a couple of tests with subgit. It seems a solid project. If
 someone wants to try it the commands for only converting trunk is (needs 6
 hours):
 {{{
 subgit configure https://svn.osgeo.org/grass/grass/trunk --layout
 directory grass_trunk.git
 subgit install grass_full.git
 }}}
 The result is a repo with 36800+ commits which is comparable to 36743.
 That's why I asked, if that was trunk only.

 I also tried to convert the whole SVN repo:
 {{{
 subgit configure https://svn.osgeo.org/grass/grass --layout std
 grass_full.git
 subgit install grass_full.git
 }}}
 but there is some problem with revision 68772. The logs suggest that it
 has to do an old SVN bug: https://subversion.apache.org/docs/issue4129 .
 This is the log:

 {{{
 SubGit version 3.3.5 ('Bobique') build #4042

 Translating Subversion revisions to Git commits...
