I have 2 branch. a branch A that was a "upgrade" branch, and a branch B that is the stable branch.
Many changes were made to branch A progressively, and many merge of B inside A were made.
Now, branch A work ok, and everything has been update, so I would like to keep all the new files and changes on certain files, but revert some to the exact version in branch B
How can I do that ?
tl;dr : I have a file in branch B that was modified and change and merged in branch A multiple time. I would like to copy the file from banch B and override the one in branch A without applying eventual change made in branch A
