Upgrade from v2.0.1.1[pls help]

I have always had issues upgrading my store. Kinda put it off for many years, but now I'm up for a challenge again.

Current store version: 2.0.1.1

I have tried the upgrade method via the upgrade file that ships with the new version and it keeps failing.

Trying to upgrade to v3.0.1.1 I get many errors like these in the system logs:
PHP Notice: unserialize(): Error at offset 0 of 203 bytes in /var/www/html/site/admin/index.php on line 41

On the web gui:

I suspect it to have something to do with my DB not being converted into the JSON(new) format.

Any assistance would be greatly appreciated

Looking at the paths and line numbers of those errors, they all look to be for 2.x files that you would have if upgrading to 3.x. How are you performing the upgrade?

Current store version: 2.0.1.1

Trying to upgrade to v3.0.1.1 I get many errors like these in the system logs:

Why 3.0.1.1 and not 3.0.3.8 ?

I'm following the upgrade steps listed in the package file: "Upgrade.txt".

1. BACKUP YOUR EXISTING STORE FILES AND DATABASE!!
- Backup your database via your store Admin->System->Backup
- Backup your files using FTP file copy or use cPanel filemanager to create a zip of all the existing opencart files and folders

2. Download the latest version of OpenCart and upload ALL new files on top of your current install EXCEPT your config.php and admin/config.php. If you are up to date with the last recent version and want to find just the new files that have changed since the last version, you can follow this guide to create a smaller changes-only patch. But for most, the full opencart zip will suffice.
Watch this video to understand how to properly upload folder using FTP: http://forum.opencart.com/viewtopic.php ... 645#p46371

3. Browse to http://<yourstore.com>/install Replacing <yourstore.com> with your actual site (and subdirectory if applicable).

4. You should see the OpenCart Upgrade script.
- If you see the OpenCart Install page, then that means you overwrote your config.php files. Restore them from your backup first. Then try again.

5. Click "Upgrade". After a few seconds you should see the upgrade success page.
- If you see any errors, report them immediately in the forum before continuing.

6. Clear any cookies in your browser

7. Goto the admin side of your store and press Ctrl+F5 3x times to refresh your browser cache. That will prevent oddly shifted elements due to stylesheet changes. Login to your admin as the main administrator.

8. Goto Admin->Users->User Groups and Edit the Top Adminstrator group. Check All boxes.
- This will ensure you have permissions for all the new files

9. Goto Admin->System Settings
- Update any blank fields and click save.
Even if you do not see any new fields, click save anyway to update the database with any new field names.

10. Other Adjustments that may need to be made, depending on which version you are upgrading from and to. These are broken down by which version they were added in. So if you are not currently at that version, you may need to make changes

I will give it a go today, but the upgrade fails with any new version.

I've tried: v2.2.0.0, v2.3.0.2, v3.0.1.1, 4.0.1.1(failed due to not having PHP8, I'm on Centos 7 and tried to upgrade to php8, but could not).

The upgrade.txt is kinda incomplete...

If you have PHP 8 on server, use this 3.0.3.8
https://github.com/opencart/opencart/tr ... aintenance

To upgrade to PHP 8 you can search on google
https://patrickdomingues.com/2021/05/01 ... -centos-7/

Only OC 4.0.x.x require PHP 8....but is not ready for production.

Last solution...pay a developer to upgrade your store

LE. See here fix for index.php error

Just tried this version and I get this message when browsing to site.com/install:

PHP Fatal error: Call to undefined function start() in /var/www/html/site/install/index.php on line 37

It clear from the errors you have posted that you haven't replaced all you existing files with the new version.

2. Download the latest version of OpenCart and upload ALL new files on top of your current install EXCEPT your config.php and admin/config.php.

Thanks for taking the time to help.

I have made sure I have copied all the files now and then was presented with PHP7.3+ needed error. I then proceeded to upgrade to PHP 8.1. The upgrade screen then loaded. I clicked upgrade and got the following errors from the GUI:

If old PHP versions are still on the server...you can add old php version in v2.0.1.1 htacces file.

I'm now running on v3.0.3.8 Thanks to all you guys!! BTW is it worth trying to upgrade to v4x?

Not at the moment, still a few too many bugs, stick with the 3.0.x.x_Maintenance branch on GitHub.
