+The method above worked well for me in my tests, even in tests with 1,000 LFS artifacts each 1mb in size. However, I have seen issues running these commands for some customers with larger repositories. Sometimes the `git lfs fetch` or `git lfs push` will hang or not appear to migrate all of the LFS artifacts. If you run into issues, you can run this script to more thoroughly (but slower) way to migrate the LFS artifacts. It works by looping through each LFS object and pushing it individually pushing it.

 ## Summary
 
 Migrating Git repositories is simple. However, if the repository contains LFS artifacts, you need to make sure to run the `git lfs fetch` and `git lfs push` commands to migrate them along with the repository. If you don't, your Git LFS files will be missing.

 The nice thing about the `--everything` option is that it also works for files that have been committed to history and subsequently deleted, so you don't have to use any additional tools to rewrite history.
