+ Written by Carlos Ruiz
+ Feel free to change everything you want, but you are using it at your own risk!
+
+ 01_FromCompiere252dTo253a.sql generated with TOAD
+ 02_migrationDictionary252dTo253a.sql generated with Karsten migration tool
+ 
+ Preparations
+ 1.	Make a database backup! Don't complain if something goes wrong,
+ 	just reapply your backup and report the error to the Adempiere forums
+ 	at: http://sourceforge.net/forum/?group_id=176962
+ 	You can use RUN_DBExport.bat in the Compiere2/utils folder.
+ 
+ 2.	Read and follow the instructions in the migration-structure.sql file.
+ 	You have to set some DEFAULT VALUES for some new columns. But it's 
+ 	done easily.
+ 	
+ Migration of Compiere database
+ 1.	This script only migrates the database from Compiere253a to 253b!
+ 
+ 2.	It's only tested with Oracle - but it should work with other databases
+ 	as well because it is just sql. If you try it with a different database
+ 	(successful or not) then please report it to the Adempiere forums
+ 	at: http://sourceforge.net/forum/?group_id=176962
+
+ 3. 	First apply the 01_FromCompiere252dTo253a.sql via any SQL tool. 
+ 	
+ 	MAKE SHURE THAT YOU FOLLOWED THE INSTRUCTIONS IN THERE FIRST!
+ 	
+ 	I use the Oracle SQL Developer (it's free but you have to register), you
+ 	can find it here:
+ 	http://www.oracle.com/technology/products/database/sql_developer/index.html
+ 	Of course you can also use Toad or even just SQLPlus:
+ 	(from the folder with the migration*.sql)
+ 	sqlplus compiere@COMPIERE_DB_NAME @01_FromCompiere252dTo253a.sql
+ 	
+ 	Dependent on the tool you use you will get some errors. They should
+ 	derive only from unrecognized comments (-> unknown command), thats
+ 	just because the sql tool treats the comments as sql commands - don't worry.
+ 
+ 4.	Apply 02_migrationDictionary252dTo253a.sql the same way.
