When possible, it is recommended to completely migrate a Subversion repository to Git; this is quite simple to do and mostly depends on the size of the Subversion repository and the organization.
If the repository follows the standard layout as described before, a migration is only a matter of minutes.
If your Subversion repository has been used from different people, you are probably interested in preserving the commit author's name, which is true even in the new Git repository.
If you have the awk command available (maybe using Cygwin in Windows), there is a script here that fetches all the users from Subversion logs and appends them to a text file we can use in Git while cloning to perfectly match the Subversion users, even in Git-converted commits:
$ svn log -q | awk -F '|' '/^r/ {sub("^ ", "", $2); sub(" $", "", $2); print $2" = "$2" <"$2">"}' | sort -u > authors.txt
Now we will use the authors.txt file in...
