======================================================================
This file contains specific instructions for upgrading your site's
version of project.module to a new release.  You should always check
this file when you download a new version to see if there are any
specific things you need to know about a certain upgrade.
======================================================================


--------------------------------------------------
Upgrading to 4.7.x-2.* (from the 4.7.x-1.* series)
--------------------------------------------------

  During the 4.7.x development of the project modules, a fundamental
change was made to the code, which resulted in the split between the
4.7.x-1.* and 4.7.x-2.* versions.  Previously, project releases were
represented via a special table in the database, and all of their
behavior was hard-coded into the project.module.  Starting with the
4.7.x-2.* series, project releases are now represented by release
nodes (see http://drupal.org/node/94000 for more information).

  To see if your site is effected, you should run the following query:

     "SELECT COUNT(*) FROM project_releases;"

     (This assumes your site is not using any table prefixing, alter
     the table name with your site's table prefix if needed). 

  If your {project_releases} table is empty, your 4.7.x-1.* or earlier
site does not use releases and upgrading to the 4.7.x-2.* series is
quite easy.  In this case, the normal upgrade procedure should be
followed, see http://drupal.org/upgrade for details instructions.
Basically:

  1) Backup your site and database.
  2) Install the latest 4.7.x-2.* release of project and project_issue.
  3) Run update.php.

  (Please note that the 4.7.x-2.* versions of project and project_issue
must be upgraded at the same time.  For example, you cannot run
project version 4.7.x-2.* with project_issue version 4.7.x-1.*).

  However, if your {project_releases} table has records, you are using
the old releases system, and upgrading your site will be a somewhat
difficult process.  In that case, you should view the following
handbook page on drupal.org *BEFORE* you start upgrading:
