I have a clone of an SVN repo on my machine for which the SVN server is unreachable. The program used for cloning is Tortoise SVN for Windows.
Is there any way to import the commit history of the repo into a git repository on github?
I tried
svnadmin dump repo/.svn > svn.dump
Resulting in
svnadmin: E165005: Expected repository format '3' or '5'; found format '12'
Which seems to be misleading, meaning I cannot dump that copy. But are there options other than dumping?
