Upgrade opencart from Version 3.0.3.6 to 4.0.2.3

Job ID: 37387568

Budget: $250 – $750 AUD

I am looking for a developer who can upgrade my Opencart website from Version 3.0.3.6 to 4.0.2.3. Here are the project requirements:

Backup: I have a backup of my current Opencart website.

Compatibility: I have custom extensions and themes that need to be compatible with the new version.
- Copy & upgrade database, including 900,000 products
- Move extensions: X-shipping pro, iSearch corporate, fastor, PayPal payment, Stripe Payment, Shipstation, ExcelPort, sitemap extension

Ideal skills and experience for the job:

- Strong experience with Opencart development and upgrades
- Knowledge of Opencart versions 3.0.3.6 and 4.0.2.3
- Expertise in handling custom extensions and themes
- Attention to detail to ensure a smooth upgrade process

If you have the necessary skills and experience, please submit your proposal for this project.

You will need to do full testing and prove that functions are working - e.g. search, order placing, customer login, etc.

We will provide a new directory on the current server, plus a new database, which will be a copy of the current website, that you can use as the staging server. We propose you do testing, and determine the exact process to upgrade everything successfully over to version 4 on that directory/database. Once you know this can be done, and exact steps, then you will need to do this within 1-2 hours on a time that we specify on the live server.
