OpenCart Community

Hello.

opencart 3.0.3.2 has an e-commerce site that is already selling. I want to make this opencart 3.0.4.0. How should I follow a path? Is it enough to send new files directly via ftp? Or is there a document about this?

My purpose in wanting to do this is to support new versions of php. php 7.2 and 7.3 remained old. The server I use no longer supports under php 7.4.

Please search the forum.
Google often provide a better search and quicker.

Do a fresh install of OC 3.0.4.0, and then install your theme and extensions, make sure the latter support PHP 8.x versions.
Use the Export/Import tool to copy over your products, categories, options, attributes, filters, and customers, see our FAQ.
Finally, use PHPMyAdmin to copy over your old orders.

It seems like all the instructions to upgrade are - fresh install, rebuild, and move data. That just seems like a lot of work for a simple upgrade (from 3.0.3.2 to 3.0.4.0, or in my case, 3.0.3.8 to 3.0.4.0). Why is that the upgrade method? I know it is Open Source and do appreciate all the work that goes into this project (my programing skills are 25 years out of date at this point so I cannot really contribute). It seems like a lot of people would just end up moving to something else if you are going to move somewhere else.

I often just upload the files and run the installer/upgrade and then fix any issues because I find the whole import/export thing and rebuilding the site to be too much of a ball ache and for a minor upgrade from 3038 to 3040 I wouldn't expect many issues (just did 3033 to 3040 with no particular issues).

However, I don't do it on a live site, always on a copy.

So yes, unfortunatly, all ways around, it involves an amount of work and isn't as simple as clicking a button.
