It's easy only if you don't care about all the people who already cloned your repo.

Recovering from remote repos renaming their default branches is no fun.

And yet, branches disappearing is not uncommon. Changing your remote branch name is trivial, but being made aware of it is the problem. It's been a while since this change was done, but if it was still being proposed, the git client saying "oi, this branch changed name" and offering to update things would be a bit more user friendly.
