How to upgrade a Plone site to a newer version
==============================================

This is a short version, more information can be found at
http://plone.org/upgrade.

1. Stop Plone / Zope

2. Always back up your Plone site. You should back up:

    * Your Data.fs which contains your site data
    * Any file system files you have modified
    * Your blob storage if you are already using blobs

3. Install the new version of Plone, this depends upon your installation.
   The latest version of Plone is always available from
   http://plone.org/download and your install will depend upon your particular
   setup.

4. Restart Plone / Zope

5. Open up the Zope root folder in a browser. It will show you an overview of
   all installed Plone sites and tell you which ones need to be upgraded.
   Follow the onscreen instructions.

Running the upgrade may:

 * Change values you have set in the ZODB, for example actions and properties

 * Re-catalog your portal_catalog, this may be time-consuming

 * Reapply security to objects, this may be time-consuming

If you have issues please search for an update of your Python, Zope, Plone and
third-party add-ons and read http://plone.org/upgrade.
If you still have issues please the use the bug tracker at
http://dev.plone.org/plone and include: your Python version, the platform, the
Plone versions you are upgrading to and from and most
important: the full traceback and upgrade log. Try to provide as much
information as possible.
