migrate from SVN to GIT

a short cheat sheet of commands I used several times to migrate SVN-repositories to GIT…

  • preparation

    
sudo aptitude install subversion git-svn
    
svn co https://my.server.private/repos/my_repo
    
cd my_repo
    
svn log q | grep -v ‘^-*$’ | cut -d ‘|’ -f 2 | sort | uniq > ../my_repo_authors.txt
    
cd ..
    
vim my_repo_authors.txt
	
      
		
    1. go ahead and edit the authors file
  • git-svn clone the subversion repository
    • 
		
  • use “—no-metadata” only if you don’t want the git-svn-id tags in the commit-messages
    
git svn clone —no-metadata —stdlayout \
    —authors-file=my_repo_authors.txt \
    https://my.server.private/repos/my_repo \
    my_repo.git-svn
    

        

    • 






    
	
  •  inspect
    


    
cd my_repo.git-svn
    
gitk —all
    
git branch -a
    

    
        
    • 
	
  •  cleanup
    


    
git clone http://github.com/nothingmuch/git-svn-abandon.git
    • 
		
  • check which of the scripts are required in your case:
    
view git-svn-abandon/git-svn-abandon-fix-refs
    
view git-svn-abandon/git-svn-abandon-msg-filter
    
view git-svn-abandon/git-svn-abandon-cleanup
    • 
		
  • FIXME: explain these:
    • 
	
	
      
		
    1. git reflog expire —all —expire=now
      2. 
		
    2. git gc —aggressive
      3. 
		
    3. git prune
      4. 
		
    4. git fsck —full
      
git config —remove-section svn
      
git config —remove-section svn-remote.svn
      
ls .git/svn .git/logs/refs/remotes/
      
ls .git/refs/remotes/
      
find .git | grep svn
      
rm -rf .git/svn/
      

      

      5. 
	
    5. add remote, push
      


      
git remote add origin git-host:my_repo.git
      
git remote -v
      
git push —all —verbose
      
git push —tags —verbose
