Upgrade from 1.3.1.1 to 1.3.7 - database issues

[prezzz]

Hello,

I need to upgrade a store based on 1.3.1.1 version to 1.3.7 - the problem is that the store is rather heavily customized (through manual updates to some files and various add-ons). No database structure was changed during those updates, only files, but it makes it impossible to perform an upgrade-mode install of 1.3.7.

I've installed the 1.3.7 version on a clean server and moves the 1.3.1.1 database (filled with orders and customers) over to the 1.3.7 version. Most things work fine, but there are some that don't work at all - for instance, ps_order_detail table is not written at all while placing orders.

Is there a way to JUST update database after such manual move between versions? Files are good now, I only need to have the database structure updated.

Best,
Prez

Have you performed the database update process? PS is able to update the current database... Take a look to readme.

Quite frankly I haven't found any such information and it would be indeed a perfect solution.
Could you point where could I find any more info on that?

You need to open up your site and run index.php script in /install/ directory.

Hm, not sure if I'm doing something wrong...
I've installed PrestaShop 1.3.7
I've installed database copied over from the 1.3.1.1 install
I opened my store's /install/index.php and it wanted to start the entire install process.
I just would like to update the database structure (of the database content moved over from 1.3.1.1) to match the 1.3.7 scheme...

Anything I would be missing here?

Click the Next button and there should be the update process.

Unfortunately there's still the same procedure as with the install going on:
- next screen is parameters checkup
- next screen is database info screen
as if it wasn't recognized at all that the store is already installed...
