+IP Reg Upgrading
+
+This version has still not reached version 1.0 (feature complete).
+As such, there may be changes at any time.
+
+There is no database upgrade logic so the database structure has
+to be compared manually.
+
+1. Check and upgrade database schema 
+Compare current database schema with the contents of the database
+creation script "mysql.sql".
+Create missing objects in your current database.
+
+2. Install new version 
+Install the new application in a new location.
+Copy the configuration file "config.php" to new installation.
+Compare the configuration to the sample config.
+There may be additional settings that you want to customize.
+
+3. Switch to new version
+Rename the old and new directory.
+
+4. Done
+If everything works fine you could remove the old directory.
