How to completely replace all branch content with commits from another branch.
Let's say:
- your project has an experimentalbranch for testing;
- you have some fixes in branch fix-345;
- you want to overwrite content and history from fix-345toexperimentalbranch;
- you don't need to save any changes in experimental.
    Then you can reset experimental branch with the following commands:
git checkout experimental
git reset --hard fix-345
git push --force origin experimental
Steps description
    git checkout  — checkout to the branch to be overwritten.
    git reset --hard  — get all changes from source branch to the target.
     git push --force origin  — force push your local changes for target branch
