SVN to Git conversion is straight forward.

1. [Optional but recommended] Create an authors file and store it under authors.txt:

graf = Sebastian Graf <sebastian.graf@uni-konstanz.de>
sebastian.graf = Sebastian Graf <sebastian.graf@uni-konstanz.de></pre>

2. Execute the clone:

git svn clone SVNREPOURL -A authors.txt -t tags -b branches -T trunk GITREPO

3. If the following errors occurs, remove the branches/tags under GITREPO/.git/config
