I'm sorry if this question has been asked many times before, but I cannot find a clear answer in previous posts.
I currently run version and I have a test environment to test upgrades, etc.
Can version be upgraded easily to version Will the upgrade script of be able to handle the database upgrade?
I tried to do this upgrade, but I get following error when running
---paste starts here-->
Notice: Use of undefined constant DB_DRIVER - assumed 'DB_DRIVER' in /myshop/install/controller/startup/database.php on line 19
<--paste stops here--

I have been able to do upgrades in the past, but I have the feeling that there are so many things that have changed, I'll never be able to upgrade my opencart.
In the meantime, I'd like to also ask a question on who is willing to help out to do the upgrade so I can hire a professional.
Please note my opencart is running on my own ubuntu server.
Any help is welcome. You can also contact me via email on

Ensure to configure your DB_DRIVER within your config.php and admin/config.php files.

The most generated errors being found on Opencart forum originates from contributed programming. The increased post counters are caused by redundancies of the same solutions that were already provided prior.
