Migrate from CS-Cart to 1C-Bitrix
Owners of CS-Cart online stores eventually hit a performance ceiling. With 5–7 thousand products, page generation times reach 2–3 seconds, MySQL lags on complex queries with attributes and variants, and standard 1C integration modules require constant tweaks—either the export fails or prices don’t sync. Migrating to 1C-Bitrix solves these problems: page performance improves 3–4 times, exchange with 1C uses standard CommerceML and works reliably. Our team has completed dozens of such migrations, and we guarantee you won’t lose a single order or SEO position.
What complexities do we face?
The most common pain point is trade offers. In CS-Cart these are option combinations, each with its own price and stock. In Bitrix they are separate information block elements (SKUs) linked to the product via PROPERTY_CML2_LINK. A simple conversion script won’t work: we need to parse CS-Cart’s option structure (types: select, radio, checkbox) and create an SKU for every combination, then migrate prices into b_catalog_price and stock into b_catalog_store_product. Bitrix documentation recommends using D7 ORM for batch loading, which yields up to 10x speed improvement over regular Add calls. We use Bitrix\Catalog\ProductTable::add for products and direct SQL for prices—this lets us process up to 50,000 SKUs per hour.
A second challenge is complex promotions. Simple product discounts transfer automatically. But combined offers (e.g., “when you buy product X, get 10% off product Y”) are stored in CS-Cart as cscart_promotions with serialised conditions. We extract those conditions, convert them into Bitrix business processes, or manually configure marketing campaigns. On one project with 40 such promotions we completed the work in 2 days.
What exactly do we transfer?
| Entity | CS-Cart table | Bitrix destination |
|---|---|---|
| Products | cscart_products |
Catalog information block elements |
| Trade offers | Option combinations | SKU information block elements |
| Categories | cscart_categories |
Information block sections |
| Orders | cscart_orders |
b_sale_order |
| Customers | cscart_users |
b_user |
| Promotions | cscart_promotions |
b_sale_discount + manual configuration |
| SEO URLs | cscart_seo_names |
301 redirects in .htaccess or SEO module |
We verify each transfer by comparing counts.
How do we guarantee data integrity?
Before starting we take a full database dump and run a project test on a copy. After migration we launch an automated comparison script: product count, order count, total revenue, active customer count. If any metric deviates by more than 0.01%, we stop and find the cause. Experience shows that with careful migration the deviation is zero. Over 10 years we have never lost a single piece of data.

| Trade offers transfer | 1–2 days |
| Orders and customers transfer | 1–2 days |
| Promotions and coupons transfer | 1 day |
| SEO redirects | 1 day |
| Testing and acceptance | 1 day |
| Total | 10–14 days |

Why migrate from CS-Cart to 1C-Bitrix?
Bitrix is the Russian commerce standard, providing reliable 1C integration via CommerceML, flexible business processes, and scalability. CS-Cart is good for starting out, but above 5,000 products it falls behind. After migration you get page load speeds 3 times higher, access to ORM, tagged caching, and built-in fiscalisation under 54-FZ. Support cost savings can reach €2,000 per year due to reduced effort for 1C and OFD integration.
Post‑migration checklist
- Check that all products appear with correct prices and stock.
- Ensure old URLs redirect to new ones (301).
- Compare a few orders between old and new systems.
- Test promotions and coupons.
- Request a data migration report.
