+
+This script help you migrate from a pre-3.0 database to 3.0 and later
+
+Changes:
+  * The propertystorage table has changed to allow storage of complex
+    properties.
+  * the vcardurl field in the principals table is no more. This was moved to
+    the propertystorage table.
+
+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;
+
+    exit();
