Yea, that's the right one to look at... sorry for the wrong link.

So you can get the code that FreeBSD used at
https://github.com/freebsd/git_conv/ which goes through things. This code
does a number of things that your organization likely wouldn't need to do.
It uses the latest different versions of the svn->git conversion tools.
Each has their pros and cons and part of the issue with this process was
evaluating which ones to use for the conversion. Not least because the
conversions can take quite a while with some of the less efficient tools....

We don't have a paper or write-up on the nuts and bolts of this conversion,
though.
