-How to rename classes of existing objects ?
-===========================================
-
-
-PyAMS provides `zodbupdate` script to update easily update the change in ZODB. Because, when you develop new features
-to PyAMS we sometimes have to rename or modify classes of already stored objects and if you do that you will never access
-yours objects
-
-
-**1) Include you package in the require resource for you webapp**
-
-
-.. code-block:: python
-
-    requires = [
-        'mypackage',
-        ...
-    ]
-
-**2) Add the Entry points**
-
-
-In the `setup.py` file add 'zodbupdate' params into entry_points where is store zodbupdate directives
-
-.. code-block:: python
-
-      entry_points={
-          'zodbupdate': [
-              'renames = mypackage.generations:RENAMED_CLASSES'
-          ]
-      }
-
-
-
-**3) Create a module named** ``generation`` **with the migration directives**
-
-
-.. code-block:: python
-
-    RENAMED_CLASSES = {
-        'mypackage.mymodule MyOldClass': 'mypackage.mymodule MyNewClass'
-    }
-
-
-**4) Run the commands** ``buildout`` .
-
-.. code-block:: console
-
-    $ mypackage/bin/buildout
-    $ webapp/bin/buildout
-
-
-The ``buildout`` command going to install correctly the package and add the new entry_points references in entry_points.txt
-
-**5)  Run the commands** ``zodbupdate``
-
-To finish run `zodbupdate` to apply the changes describe in `RENAMED_CLASSES`
-
-.. code-block:: console
-
-    $   bin/zodbupdate --config etc/zodbupdate-zeo.conf
-
-
-Where `zodbupdate-zeo.conf` is the configuration file to access to the ZODB.
