No upgrade option

[audiografix]

Hi, I am just about to upgrade to 1.3.8a from 1.3.0 but do not get an option to upgrade within the install menu.
I have noticed in the instructions that apparently in this case, the install system cannot verify the database structure etc. and that I need to check my configure.php files.
The question is, what exactly am I looking for?
The system obviously recognizes the database.
Can I not do a fresh install and then import the data into the database again?

Any help would be appreciated.
