This process worked for me. I take no responsibility for any damage or loss incurred as a result of following or not following these steps or, for that matter, anything else you might do or not do.
- SVN is hosted at 
svn.domain.com.au. - SVN is accessible via 
http(other protocols should work). - GitLab is hosted at 
git.domain.com.auand:- A group is created with the namespace 
dev-team. - At least one user account is created, added to the group, and has an SSH key for the account being used for the migration (test using 
ssh [email protected]). - The project 
favourite-projectis created in thedev-teamnamespace. 
 - A group is created with the namespace 
 - The file 
users.txtcontains the relevant user details, one user per line, of the formusername = First Last <[email protected]>, whereusernameis the username given in SVN logs. (See first link in References section for details, in particular answer by user Casey). 
- subversion version 1.6.17 (r1128011)
 - git version 1.9.1
 - GitLab version 7.2.1 ff1633f
 - Ubuntu server 14.04
 
git svn clone --stdlayout --no-metadata -A users.txt http://svn.domain.com.au/svn/repository/favourite-project
cd favourite-project
git remote add gitlab [email protected]:dev-team/favourite-project.git
git push --set-upstream gitlab masterThat's it! Reload the project page in GitLab web UI and you will see all commits and files now listed.
- If there are unknown users, the 
git svn clonecommand will stop, in which case, updateusers.txt,cd favourite-projectandgit svn fetchwill continue from where it stopped. - The standard 
trunk-tags-brancheslayout for SVN repository is required. - The SVN URL given to the 
git svn clonecommand stops at the level immediately abovetrunk/,tags/andbranches/. - The 
git svn clonecommand produces a lot of output, including some warnings at the top; I ignored the warnings.
