Amazon integration + migration from Opencart 1.5 to Opencart 3.0

The concepts of version updates or migrations do not exist in OpenCart. 1.5 is a very outdated version, with 3 there are differences in everything. This is a new site, new modules, template, etc., everything old is the transfer of content (products, categories, customers, orders, articles, etc.). This is a slightly different price and volume of work, for which a lot needs to be compiled and approved, from the amount of necessary functionality to the new visuals, etc. Write in private messages, we will discuss.

Good day!

We are the SDEV team, specializing in complex web development and system integration. We have experience migrating stores from Opencart 1.5 to 3.0 while maintaining SEO metrics, including proper 301 redirects, transferring meta tags, configuring robots.txt and sitemap. We will ensure a smooth transition without losses in indexing and will promptly update data in Google Search Console.

We will also implement complex product display logic with multiple codes, as in your current solution: separate products, groups, and sets with clickable elements — everything will work with search results and filtering. We will write or adapt a module to fit your structure to maintain functionality.

We will recreate the menu to be intuitive, with logical navigation through categories. For registered customers, we will set individual prices linked to their accounts.

Regarding integration with Amazon — we have experience connecting and configuring product export modules to Amazon via XML and API. We will implement stable synchronization of stock, prices, and orders.
…
An example of a similar case: Automotive search and monitoring — a complex bot for automated searching and monitoring of cars across different platforms with instant notifications.

We are ready to take on the project and execute everything with high quality, adhering to all technical requirements.

Good day!

Migration from OpenCart 1.5 to 3.0 while maintaining SEO positions is my specialization. I see two key risks in the project: (1) maintaining the URL structure + 301 redirects for each old path, (2) custom logic for displaying products through id_product ranges (2M) — requires migration not only of the database but also rewriting the product card templates.

My approach:
Stage 1 (14 days) — migration of the core from 1.5 to 3.0, 301 redirects, transfer of meta tags/content, robots/sitemap/Search Console, adaptation of the XML export module.
Stage 2 (separately) — custom menu, logic "code/list/set", individual B2B prices, integration with Amazon.

I work as JDG (Poland), issuing VAT-EU invoices.
…
Before starting: can you provide access to the current site + a database dump to confirm the estimate?

I propose 550 EUR for Stage 1 in 14 days. We will discuss Stage 2 after the migration is completed.

I would be happy to have a 15-minute call — I will show case studies of e-commerce migrations.

Best regards,
Edward Dworecki / Servify Labs

I can migrate to version 3, I have already transferred version 2 to 3, so I already have experience. I will migrate the database and set it up on your dev environment or come up with an alternative. Of course, it’s better not to touch anything on the live site for now; the transfer should be done at the end of the project, at night, if everything is okay.

Dear Client,

Thank you for the detailed technical specification — the task is clear and quite complex. Below is my proposal for migrating from OpenCart 1.5 to 3.0 while preserving SEO and enhancing functionality.

Scope of Work
Migration and SEO Preservation
Transfer of the site from OpenCart 1.5 → 3.0
Preservation of URL structure or setting up 301 redirects
Transfer of all meta tags (title, description, keywords)
… Transfer of content (products, categories, descriptions)
Checking and configuring robots.txt and sitemap.xml
Setting up and updating in Google Search Console

Catalog and Product Functionality
Implementation of product display logic:
— single product
— group of products (multiple codes)
— set (with composition and clickable items)

Solution:
Development of a custom module (or enhancement of the existing one) with logic:
linking products through a separate table
correct functioning of search and filters
SEO-friendly pages

Additional Functionality
Selection and configuration of XML export (similar to the current one)
Recreation of a convenient and understandable menu
Implementation of individual prices for clients (groups / personal prices)
Integration and configuration of export to Amazon
Testing of all scenarios (search, filters, product cards)

My Stack
OpenCart (1.5 → 3.x migrations)
PHP / MySQL
OCMod / VQMod
SEO (redirects, structure, indexing)
XML / API integrations (Amazon, feeds)

Important Points
SEO positions are maximally preserved (through redirects and structure)
Code without "hacks" — convenient for further support
Possibility of scaling and enhancements
Support after launch

Conclusion
The project requires not just a transfer, but a competent migration while preserving SEO and the business logic of the catalog. The implementation of your unique product structure is especially important — this will be done through a reliable custom solution without losing the functionality of search and filters.

I am ready to discuss the details, review the current site, and propose an exact implementation plan.

Sincerely,

Hello,

My name is Jeo Vincent Carretas, and I am interested in your project. I have experience working with OpenCart migrations and understand the importance of preserving SEO during the process. I can migrate your store from OpenCart 1.5 to 3.0 while maintaining URL structure or setting up proper 301 redirects, and ensuring all meta data, content, robots.txt, and sitemap are correctly transferred.

I can also handle custom functionality, including implementing the product display logic based on ID ranges, making sure search and filters work properly, and recreating a clear and user-friendly menu. Additionally, I can set up customer-specific pricing, integrate an XML export module, and configure an Amazon export solution.

I am confident in working with existing systems, finding the right modules or developing custom solutions when needed, and ensuring everything works smoothly after migration.

I am ready to start and would be happy to discuss the details and timeline with you.
…
Thank you for your time and consideration.

Best regards,
Jeo Vincent Carretas
