I created a branch, for example, mycode. Then the necessary changes made, made Commit, Push. Now I thought that I would make some more similar branches with a similar functionality and rename the first in the API_MYCODE. Can this be somehow made?

To rename a branch downloaded to a remote server, you first need to rename the branch locally, and then unload changes back, deleting the previous branch on the server.

git branch -m old_Ancing new_Ancing
Git Push Origin: Old_Nolding New_Ancing

In the second line, pay attention to the colon in front of the old name of the branch – this is a command for removing the branch on the server.
