Fantastic tutorial! Everything went smoothly. Easy to understand and follow. I like when people actually talk you through the tutorial. Well done!

Hey Alex, thanks for information... Now one little big problem in there which no one has spoken about so far which is the missing tables in MySQL databases from an older version to a newer and here is the question, why it is not clear how do we move further with the SQL DB?

I have done more than 30x installations excluding my hosting trials and always fails to restore my DB as well as my OC files successfully.

I would really appreciates your efforts and explanation.

P.S. I have uninstalled all the 3rd party modules and backed-up my DB and still never works.

Sincerely,
Spinner

Thank you for the video.

Got a question, did you replace the new .htaccess files from opencart's 1.5.6.1 folder with your currrent one?

Thanks for sharing this info!
One question: since I'm new to OpenCart, I was wondering how will an older OC 1.5.4 theme react to the upgrade to 1.5.6.4?

At 3.08 you move to your 'tutorial' root directory. What is the root directory I should move my files to? I am new to this and had to abandon the upgrade at this point in the video. Solved - I found the root directory. Upgraded from 2.0 to 2.0.01 successfully but my store is now all messed up.

Has anyone successfully upgraded from Opencart 2.0.0 to 2.0.1.1?? I haven't made the attempt yet since there haven't been any formal documentation released about the process (or is there? I couldn't find any). The Opencart forums are full of users who have been unsuccessful so far. Any help would be greatly appreciated. Would also be great if you could post a new video tutorial that we can share with fellow users who are in the same position. Thanks
