How do you merge two Git repositories?

Question

Consider the following scenario:

I have developed a small experimental project A in its own Git repo. It has now matured, and I\'d like A to be part of larger projec

Answer 1

To merge a A within B:

1) In the project A

git fast-export --all --date-order > /tmp/ProjectAExport

2) In the project B

git checkout -b projectA
git fast-import --force < /tmp/ProjectAExport

In this branch do all operations you need to do and commit them.

C) Then back to the master and a classical merge between the two branches:

git checkout master
git merge projectA
