+This document describes the steps to follow to migrate from a version 3.4.0 of Tiny ERP server to a version 4.0.0
+
+Warning: the migration scripts involved in this migration are only meant for 
+a standard Tiny ERP installation. It might not work or even break some data 
+if you added or modified some code to the default Tiny ERP distribution.
+
+To migrate a 3.4.0 server to version 4.0.0 you should:
+
+- stop Tiny ERP server 3.4.0
+
+- backup your database
+	For example: pg_dump terp340 > backup340.sql
+
+- run the pre.py script (located in this directory)
+	You might need to pass it some optional arguments so that it can connect 
+	to the database.
+
+	For example: python pre.py -d terp340
+
+- run TinyERP server 4.0.0 with "-d terp340 -u all" in the parameters
+	For example: ./tinyerp-server.py -d terp340 -u all
+
+- stop TinyERP server 4.0.0
+
+- you are ready to work with the new version.
