title: How to reconnect git branches to master after migration from svn?
body: <p>I have migrated a large svn repository to git using <a href="https://github.com/nirvdrum/svn2git" rel="nofollow noreferrer">svn2git</a>. Now I have the following situation:</p>
  
  <p><a href="https://i.stack.imgur.com/CkmBf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/CkmBf.png" alt="git branch disconnected from master"></a> </p>
  
  <p>The image is from my GitLab overview. As you can see, the branches created with svn are not connected to the red master branch. Is it possible to "reconnect" the initial green commit to the master branch? Because of this, every branch is about 5k commits behind master and I'd like to fix that.</p>
  
  <p>Thank you!</p>
