更改分支基數 - Change branch base

問題：

I've a tree like this:我有一棵這樣的樹：

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

and I have to move the PRO branch to master我必須將 PRO 分支移動到 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.我已經嘗試了 PRO 分支的git rebase master ，但沒有任何反應。

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，然後我不得不製作一個產品演示（ 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.然後，我錯誤地從演示創建了另一個分支（ git checkout -b PRO和一些提交），現在我需要將 PRO 分支移動到 master 並保持演示完好無損。 At the end, both demo and PRO will hang from master.最後，demo 和 PRO 都將掛在 master 上。
