customize template.ini to upgrade from msde to express edition?

[hvisionexpo]

I need to create the script to upgrade the current named instance of sql server 2000 desktop engine to sql server 2005 express edition. I am having difficulty preparing the template.ini and would appreciate help.

When i use this template.ini it logs an error that this instance already exists and fails the instance upgrade.

1. named instance (MY_INSTANCE) of msde 2000 is already installed
2. uses sql authentication, sa user/password = sa/mve
3. tcp/ip is enabled



content of template.ini


ADDLOCAL=All
UPGRADE=All
INSTANCENAME=MY_INSTANCE
SQLACCOUNT=sa
SQLPASSWORD=mve
