In Git for Windows, `git svn` is quite a maintenance burden (with a few known issues) and my current thinking is to drop it from Git for Windows instead of leaving it in the current shape (I, for one, cannot justify working on it myself, and the same seems to hold for everybody else, too). See also https://github.com/git-for-windows/git/issues/5405.
Is there a chance that you could use the [Windows Subsystem for Linux (WSL)](https://learn.microsoft.com/en-us/windows/wsl/) (i.e. the Linux version of Git) for this migration, especially given that the characterization as "migration" suggests that this is a one-off task?
Ciao, Johannes
