Migrate an svn repo with large files to a new git repo?

Question

I have converted my svn repo, with files larger than 100 mb, into a git repo with git-svn. Everything went swimmingly. Then I attempted to upload the repo to GitHub, and I got an error that a file was too large. I followed the link to git lfs , I set it up without a hitch. I assigned the file extensions of the files that were too large to the .gitattributes section, and during my upload, everything seemed to work well. git lfs uploaded the large files, and then git uploaded the rest - but there was still the same error from the same file! So I looked for this file, and I couldn't find it within the repo. I think it must have been made in an earlier commit, and later deleted. I suppose I could delete the tracked, large file, but that would be editing the history. Is there any way for lfs to track files in previous commits when uploading a repo? Or is something else going on? Here's my console output:

Any help is much appreciated!!

I ended up using BFG Repo-Cleaner to clean all the large files out of my previous commits. It worked very well. Then I pushed the repo and no more error.
