OpenCart → Shopify technical demonstration

I migrated part of the data from the previous OpenCart store on valisimo.com to a separate Shopify store. The demonstration shows the data selection, the import, the new interface and the map of old and new URLs.

See before and after An assessment for your store

This is my own project, not a client project. The Shopify store is behind a password and does not take real orders or payments. valisimo.com remains the Shopify studio’s website.

Imported data

What data was imported

The OpenCart database held 56 product rows. Only 9 had an active Bulgarian record and belonged to the catalogue; the other 47 sample or unsuitable records were left out, not carried over ‘just in case’.

Comparing the two stores

How the interface changed

The product data was kept, and the navigation, the product pages and the basket were reworked for Shopify.

Information architecture
Before Repeated menus, categories with no products and two URLs for the men’s category.
After One catalogue, two collections and 19 checked pairs of URLs.
Product data
Before A mix of Bulgarian records, English sample content and outdated sales copy.
After 9 products, 9 variants and 33 valid images in a model with no personal data.
Path to an order
Before Unclear icon-only actions, empty ratings and a partly untranslated basket.
After Visible availability, clear terms and consistent actions in Bulgarian.
Use on a phone
Before The mobile menu is a separate white list, with no order by task, no context and no direct ways into buying.
After A dedicated mobile menu with a clear hierarchy and separate ways into the two collections.

A visual archive before the switch-over

Comparison: OpenCart and Shopify

The screenshots were taken on 24 August 2026 and show the old OpenCart interface and the protected Shopify demonstration.

01 · Home page

Home page

  • One leading message and one main action on the first screen.
  • The product photos from the old catalogue are kept.
  • Every page states that the demonstration does not take orders.
The new Shopify home page, with a large product image, a clear headline and two actions. Before · OpenCart After · Shopify
The Shopify version opens with the main offer and direct links to the products, instead of several blocks of equal weight.
The old OpenCart home page, with a small logo, a horizontal menu, a large slider and product tabs.

02 · Navigation on a computer

Navigation on a computer

  • The collections are grouped under Catalogue.
  • The active state is visible with a mouse and with a keyboard.
  • The message at the top is separated from the main navigation.
The new Shopify navigation on a computer, with the Catalogue menu open, showing collections, promotional products and help with ordering. Before · OpenCart After · Shopify
The Catalogue menu brings the collections, the promotional products and help with ordering together in one place.
The old OpenCart navigation on a computer, with a small logo, a dense row of categories and separate action icons.

03 · Catalogue and collections

Catalogue and filters

  • 56 rows are reduced to 9 products; 47 sample or unsuitable records are dropped.
  • Availability is visible on the card itself, instead of only after opening the product.
  • The two old URLs for the men’s category are matched to one Shopify collection in the documented URL map.
The new Shopify men’s watches collection, with eight migrated products, compact filters, availability and prices in euro. Before · OpenCart After · Shopify
The comparison is now category against the same category: men’s watches. Shopify puts the eight migrated men’s products, availability and price at the centre of the task.
The old men’s watches category, with a left column, a blog block, sort options and a product grid.

04 · Product page

Product information

  • The specifications are cleaned up and arranged as a short list, without outdated sales copy or a phone number.
  • Availability, delivery and returns are visible before the add to basket action.
  • The name is normalised for reading, and the old and new URLs are linked in the documented map.
The new Shopify product page of the Good Boy women’s watch, with four large photos, a promotional price in euro, availability, terms and a clear add to basket. Before · OpenCart After · Shopify
Good Boy is kept with its four photos and its promotional price of BGN 29.99 → BGN 15.99, shown after the migration as €15.33 → €8.18. The outdated social buttons and the empty ratings were not carried over.
The old OpenCart product page of the Good Boy women’s watch, with a gallery, a promotional price, social icons and an empty rating scale.

05 · Basket

Basket

  • The controls have clear, accessible text names, not icons alone.
  • The free delivery threshold, the estimated total and the key terms are shown.
  • The test environment demonstrates the whole path to an order, but does not allow a real payment.
The new Shopify side basket, open on the right over the collection, with the product, quantity, delivery, payment and estimated total. Before · OpenCart After · Shopify
The basket opens at the side over the current page. Quantity, total, delivery, payment and the right of withdrawal are shown together.
The old OpenCart basket, with a product table, partly English headings and separate panels for coupon, delivery and voucher.

06 · Navigation on a phone

Navigation on a phone

The old menu is a separate white list of six equal links, with no grouping by task and no context for the catalogue. The new menu adds a clear hierarchy, large touch targets and direct ways into the men’s and women’s collections.

  • Catalogue contains only collections that have real migrated products.
  • Search, account and basket stay visible without competing with the main menu.
  • Closing is visible, and every main area keeps a readable text label.
The open OpenCart mobile menu, with six links of equal weight and a separate close button.

07A · Home page

Home page on a phone

The new Shopify home page on a phone, with a readable headline, a product image and clear actions. Before · OpenCart After · Shopify

07B · Product page

Product page on a phone

The new Shopify product page of Good Boy on a phone, with a large image, a readable name, the price and availability. Before · OpenCart After · Shopify

07C · Basket

Basket on a phone

The new Shopify side basket on a phone, with the product, quantity, delivery and estimated total in order. Before · OpenCart After · Shopify

No personal data was used

What the demonstration does not include

The demonstration uses the product catalogue, the categories, public pages and posts. Personal data and data about how the store was run reach neither Shopify nor the public files of this demonstration.

  • Customers and addresses
  • Orders and payments
  • Passwords and sessions
  • IP addresses and logs

A separate demonstration store

The demonstration store is separate from valisimo.com

The Shopify store was created only for this technical demonstration. No DNS switch-over is planned, and valisimo.com remains the studio’s public website.

  1. 01The 19 old URLs are checked against their exact Shopify matches.
  2. 02The map stays as documentation and is not applied to the studio’s domain.
  3. 03Old store URLs with no real replacement on the site return a genuine 404.

A protected technical demonstration

The demo store is password-protected

Bulgarian is the only published language. The password separates the demonstration environment from the public site, indexing and real orders. The password is not published here; if needed, I give controlled access for a review.
