TFS

We have 2 team projects in TFS 2015.
The first one was the old version (Version-A) which is from Visual Source Safe before which was successfully migrated to TFS 2015 without losing history.

Then, there is this new another project(Version-B) which is the latest version of the old project before. This is currently used in development for the past 3 years.

Is there a to combine this two team projects without losing the history (changesets, who made the changes) ?

What I have tried:

I create a branch of the Version-A project and merge it to Version-B root. But the history details was not transferred.

The TFS just log the when did I merge the project.

Kindly help. Thank you
