Hello,
I am currently using OC 4.0.2.1 with a populated database containing products, categories, orders, etc. However, it seems that not all extensions are available or compatible with the latest 4.x version.
Due to numerous errors and defective functionalities, I am thinking of downgrading to version 3.0.3.9. Is this a feasible option?
Thanks.
See also our FAQ on this. The procedure for a downgrade is the same as for an upgrade.

Yes, I think that still makes sense at this point.
I believe 4.0.2.4 will have OCMOD and at that point I think extensions will start to be upgraded much faster as it will be much easier for developers.

Perfect, this sounds good.paulfeakins wrote: ↑Fri Jan 05, 2024 12:11 amYes, I think that still makes sense at this point.

Currently, I don't have any extensions installed; it's only OC 4.0.2.1 with Journal 3.2.
I'm unsure about the process of moving to OC 3.0.3.9.
Should I install OC 3 first, then proceed to install Journal 3.2, followed by exporting/importing Journal settings? Additionally, do I need to copy the 'images' folder? do I have to export / import SQL database ?
I apologize for any confusion, as I typically handle upgrades.

Well, you have more than just a few Extensions installed by use of Journal 3 !

Not Journal is the problem, because has option to export/import design very quick

You need to decide whether you want to use the Journal3 framework, or the OpenCart framework. A Journal3 framework has several times more PHP files than the whole of OpenCart, with a different framework, and IMHO poor software engineering quality. If you use Journal then for future issues you should contact the Journal support.

Suppose I'm working with a clean installation of OC4 without any theme or extensions and opt to downgrade to OC3. What approach would you recommend from your perspective?JNeuhoff wrote: ↑Fri Jan 05, 2024 8:35 pmYou need to decide whether you want to use the Journal3 framework, or the OpenCart framework.

You could do a fresh installation of OC 3.0.3.9, or better, OC 3.0.x.x, and then use the Export/Import tool to copy your attributes, options, filters, categories, and products over to your site, see also this post. And use PHPMyAdmin to export/import as CSV-files some other DB tables, as needed.

I would suggest 3.0.3.9 is better because it is a fixed version. 3.0.x.x is a moving target that will vary depending on when you download it.JNeuhoff wrote: ↑Fri Jan 05, 2024 10:13 pmYou could do a fresh installation of OC 3.0.3.9, or better, OC 3.0.x.x
Jeff's excellent Export/Import tool should do the job. Create a fresh 3.0.3.9, export from your current 4.0.2.3 and then import into the 3.0.3.9.

The OC 3.0.x.x is based on 3.0.3.9, with some further bugfixes. Maybe at some stage it might be a good idea to do a 3.0.3.10 or 3.0.4.0 release.

OC v3.2 is still under development and is also bugs-free from diagnostics. Some completion to features need to be done. Other than that, it's quite flexible to use: https://www.github.com/opencart/opencart-3 until OC v4.0.2.4 gets officially released.

PHP 8.3 is also compatible on opencart-3.

Indeed, but that means if someone says they are running OC 3.0.x.x you do not know exactly what code they are running.

It might make sense, after some more bugfixes, though no new features or functionality changes, to make another release, e.g. 3.0.3.10 or maybe 3.0.4.0. It would still be highly backward-compatible with existing OC 3 extensions.paulfeakins wrote: ↑Mon Jan 08, 2024 7:25 pmIndeed, but that means if someone says they are running OC 3.0.x.x you do not know exactly what code they are running.

Agreed.
We should stick to the proper version numbering system rather than sloppy things like 3.0.x.x where the code could be anything depending on when you download it.

Nowadays, while focusing on bugfixes, OC v4.x releases would be more worth the time spending especially due to the integrated cron features whereas payment extensions are now getting integrated as opposed to previous versions requiring all the manual tasks to complete the repeated orders.
