Problem upgrading 0.19 to 1.1.0rc2

[sagb@elia]

Hi,
I'm trying to upgrade from 0.19.x to 1.1.0rc2.
Web server is IIS on Win2003.
Database is MySQL 5.0.22 running on Win2003.

The fact is "upgrade.php" never appears, no new record appear in "mantis_upgrade_table".
And when I log in, an error occurs because of a missing column.

Can anyone help?
How can I check the database was upgraded or not?
Where can I get an upgrade script?

The update.php script doesn't run on its own. You need to envoke it.

Thanks, but the manual says

If you are upgrading from a pre-1.0.0 (including 1.0.0a* or 1.0.0rc*) installation to 1.0.0, access http://yoursite/mantis-release/admin/upgrade.php. This will upgrade your database to 1.0.0. Once your database has reached release 1.0.0, you can use the method listed below.

That's exactly what I did but nothing happened...
Am I missing something?

Well, I resolved this one... Looks like the install.php was ran before the upgrade.php.
