将GIT仓库移至另一个仓库

Question

How do I achieve the following? I have a new repo New_Repo which is the current repo we all are working on. I would like to create WhatINeed, but have repeatedly failed to do so.

I understand that the commit ID will change and we are fine with this.

Old_Repo ........................... (Master, which is also v1)
            |......... (ModA) 

New_Repo.(Empty Master)
        |............. (v2)

WHatINeed.(Empty Master)
         |........................... (v1)
         |       |......... (ModA)
         |............. (v2)

I have been able to get to add the Old_repo/master onto the WhatINeed master. But its not a branch like I want it.

I am already refering to Insert a commit before the root commit in Git? But this gives me a flat structure without the ModA branch. Is there something wrong?

Thank you in advance.

If I understand correctly, you want to create a new branch (say, oldRepoBranch ) into WhatINeed repo that will have the same commit history of Old_Repo's master branch.

Add a new remote (say, oldRepo ) with the url of Old_Repo into WhatINeed repo.

// WhatINeed repo
$ git remote add oldRepo <Old_Repo url> 
$ git fetch oldRepo

Create a new branch oldRepoBranch with the history of ldRepo/master .

$ git checkout -b oldRepoBranch oldRepo/master
$ git log 
// oldRepoBranch commit history = Old_Repo/master commit history
