How do I move an existing repository under another also existing repository on the same server

[Uday Dattani]

Hi, I am in the process of consolidating multiple BItBucket repositories into a single one.

I have a multi-module maven project in a repository A.git on my company's BitBucket server.

Currently, another independent maven project exists in another repository B.git on the same BitBucket server.

How can I move this B.git with all its history under A.git, so I could make B a sub-module of A, and then eventually deleting the top level B.git. Now B only exists under A.git, with its independent history still available.
