更改分支基数 - Change branch base

问题：

I've a tree like this:我有一棵这样的树：

(commit 1) - master
                \-- (commit 2) - (commit 3) - demo
                                                \-- (commit 4) - (commit 5) - PRO

and I have to move the PRO branch to master我必须将 PRO 分支移动到 master

(commit 1) - master
                |-- (commit 2) - (commit 3) - demo
                \-- (commit 4) - (commit 5) - PRO

I've tried a git rebase master from PRO branch, but nothing happens.我已经尝试了 PRO 分支的git rebase master ，但没有任何反应。

To clarify : I was working in master and then I had to make a product demo ( git checkout -b demo and some commits).澄清一下：我在 master 工作，然后我不得不制作一个产品演示（ git checkout -b demo和一些提交）。 Then, by mistake, I create another branch from demo ( git checkout -b PRO and some commits) and now I need to move PRO branch to master and leave demo intact.然后，我错误地从演示创建了另一个分支（ git checkout -b PRO和一些提交），现在我需要将 PRO 分支移动到 master 并保持演示完好无损。 At the end, both demo and PRO will hang from master.最后，demo 和 PRO 都将挂在 master 上。
