is there an easy way to move a subtree added using the following cmd
git subtree add --prefix=<prefix> <repository> <commit>
in other terms, is it possible to change prefix from dir1 to dir2.
the answer to git subtree: possible to change subtree branch/path in a forked repository? suggests to remove the subtree then add it back.
It doesn't work for me because I need to preserve local commits, is there another way?
One alternative is splitting from your current commit that include the local commits you want to preserve:
git subtree split --prefix=dir1 HEAD
# Create a branch with the printed commit just to use it later
git branch split_dir_1 <split_commit>
And then do what was described it in the question you mentioned, delete the subdirectory and re-add the subtree.
git rm dir1
git commit
git subtree add --prefix=dir2 . split_commit
Bear in mind that by doing this you will still be able to see in the repository history when the first subtree was created and deleted and re-added.
