title: Can I delete the django migration files inside migrations directory
body: <p>I personally like django for its MVC ideals. But while i am running Django migrations in version 1.7 each and every migrations i do in it is stored inside the migrations directory. If i delete those file it is throwing an error while migration. </p>
  
  <p>I Tested like this. I created a new Django project and initiated a git repo . I ran some 3-4 migrations in Django which resulted in 
  3-4 migration files under the migrations directory. I tried deleting the very older migration files i.e (1st and 2nd migration files) and tried to run </p>
  
  <pre><code>python manage.py makemigrations
  </code></pre>
  
  <p>which does cause some error like "migration files not found". Later i did a git stash which restored the deleted files. Now i tried to run the same command again and it was working fine.</p>
  
  <p>What my question is if a person runs some 50 changes in db during development all the migration files are stored in migrations directory. Is it possible to delete those files and do changes to db again without any interruption?</p>
