+
+This script help you migrate from a pre-2.1 database to 2.1.
+
+Changes:
+  The 'calendarobjects' table will be upgraded.
+  'schedulingobjects' will be created.
+
+If you don't use the default PDO CalDAV or CardDAV backend, it's pointless to
+run this script.
+
+Keep in mind that ALTER TABLE commands will be executed. If you have a large
+dataset this may mean that this process takes a while.
+
+Lastly: Make a back-up first. This script has been tested, but the amount of
+potential variants are extremely high, so it's impossible to deal with every
+possible situation.
+
+In the worst case, you will lose all your data. This is not an overstatement.
+
+Usage:
+
+php {$argv[0]} [pdo-dsn] [username] [password]
+
+For example:
+
+php {$argv[0]} "mysql:host=localhost;dbname=sabredav" root password
+php {$argv[0]} sqlite:data/sabredav.db
+
+HELLO;
