Migrate from HubSpot to Bitrix24: Data Migration Without Loss

Manual export from HubSpot to CSV followed by import into Bitrix24 often leads to losses: connections between contacts and deals break, communication history fragments, custom fields remain empty. Moreover, organizations face risks — lost data can cost up to 30% of revenue. We migrate data directly via HubSpot API v3 and Bitrix24 REST API, preserving the link structure and history. The team has 5+ years of experience and over 50 completed projects. Get a consultation for your project — we will assess the data volume and offer an optimal migration plan without data loss.

Why HubSpot to Bitrix24 migration is harder than it seems

HubSpot API v3 provides access to all objects: contacts, companies, deals, tickets, engagements. But the link structure differs. HubSpot uses associations with multiple links; Bitrix24 uses a flatter model with one primary company per contact. Without prioritizing multi-links, data can be lost. Additionally, HubSpot allows arbitrary properties for each object, which must be mapped to user fields. HubSpot API documentation describes over 20 field types, each requiring precise matching.

How to migrate contacts and deals

Export through HubSpot API uses cursor pagination:

$after = null;
$contacts = [];
do {
    $params = ['limit' => 100, 'properties' => 'firstname,lastname,email,phone,company'];
    if ($after) $params['after'] = $after;
    $response = $hubspot->get('/crm/v3/objects/contacts', $params);
    $contacts = array_merge($contacts, $response['results']);
    $after = $response['paging']['next']['after'] ?? null;
} while ($after);

Import to Bitrix24 via REST API: crm.contact.add, crm.company.add, crm.deal.add. Standard field mapping (email, phone, name). It's important that phone numbers in Bitrix24 are stored as an array, so multiple numbers must be passed via PHONE with type WORK or MOBILE.

Object mapping table

What about custom fields?

HubSpot allows arbitrary properties for each object. Get the schema via /crm/v3/properties/contacts. For each custom field, create a user field in Bitrix24 via crm.userfield.add. Types are mapped:

What risks during migration and how to avoid them?

The main risk is losing object relationships due to differences in data models. To minimize this, we use multi-stage testing: first migrate a small sample (100–500 records), verify mapping and link correctness, then run full migration. Additionally, we set up error logging for every REST API call. If a record fails due to a duplicate or incorrect field, we log it and handle separately. Integrity is guaranteed by certified specialists with years of experience.

Scope of migration work

The migration includes full export via HubSpot API (contacts, companies, deals, activities, associations), creation of user fields in Bitrix24, mapping and transfer of communication history (emails, calls, meetings), configuration of deal pipelines and stages, multi-stage testing after transfer, delivery of mapping documentation, and team training.

Work process

1. Analyze source schema: collect list of objects, custom fields, associations.
2. Design mapping: determine field and type correspondences.
3. Develop migration scripts in PHP using HubSpot API and Bitrix24 REST API.
4. Test migration on a small sample (100–500 records) for verification.
5. Full data migration, including communication history.
6. Final testing: record count comparison, random checks of deals and contacts.
7. Deployment and user training.

Typical timelines and guarantees

We guarantee data integrity and minimal downtime. Migration via HubSpot API is an order of magnitude faster than manual CSV export.

Why URL Structure Matters in Bitrix Migration?

Skipping URL mapping during a website migration to Bitrix crashes organic traffic by 50–80% in two weeks. WordPress uses /product/item-name/, OpenCart uses /index.php?route=product/product&product_id=123, Bitrix defaults to /catalog/section/element/. Without a 301 redirect map, search engines index mass 404s. We start every migration with Screaming Frog scanning the old site, then compile a complete redirect map before writing a single line of code. Proper migration requires full URL mapping — every indexed page gets a correspondent.

Over seven years we have completed 50+ projects: landing pages, catalogs with 300,000 products, e‑commerce stores. Typical duration 2–8 weeks. Contact us for a free project estimate within one day.

How Migration Preserves SEO Positions

Losing organic traffic is the biggest fear, and it's justified. Here is how we avoid it.

• URL mapping 1:1 — where possible, via CUrlRewriter and infoblock SEF settings we keep the exact structure. When impossible — 301 redirect. Auto‑generation of redirect map: parse Screaming Frog export, match with new element slugs, generate nginx config. Each redirect verified with curl -I after switching.
• Transfer of meta tags — title, description, h1 moved into properties ELEMENT_META_TITLE and ELEMENT_META_DESCRIPTION. Canonical via Bitrix SEO component. Duplicates cut: www/non‑www, http/https, sorting parameters. Sitemap: new sitemap.xml generated by Bitrix seo module, submitted to Search Console immediately after DNS switch.
• Speed comparison — Bitrix processes a catalog of 100,000 products 3x faster than OpenCart due to tagged caching and query optimization for b_catalog_product.

What Data Gets Transferred?

Content — pages, articles, news → information infoblocks. Catalog: categories → sections, products → elements linked to b_catalog_product, properties → infoblock properties or highload directories. Images, reviews, FAQ.

E‑commerce — products with trade offers (SKUs), prices in b_catalog_price (multi‑currency via b_catalog_currency), stock balances b_catalog_store_product, discounts (b_sale_discount), order history (b_sale_order + b_sale_basket).

Users — client base b_user plus custom UF fields. Passwords are hashed differently: WordPress — phpass, OpenCart — SHA1+salt, Drupal — SHA512. We write a custom CUser::LoginByHash with fallback to old algorithm — client enters password once, system rehashes to Bitrix bcrypt.

SEO data — meta tags, alt attributes, URL structure. Main task: preserve every indexed URL or set 301.

Media — images, documents, videos — transferred preserving paths and optimized via CFile::MakeFileArray().

How to Plan a Successful Migration: 5 Key Steps

1. Audit — scan with Screaming Frog: all URLs, status codes, meta tags. Analyze DB structure, custom modifications, integrations. Create migration map.
2. Architecture design — map content types → infoblocks, fields → properties, directories → highload blocks. Architecture must be convenient for Bitrix administration.
3. Migration scripts — PHP scripts read from old DB (or API), transform and write via Bitrix API (CIBlockElement::Add, \Bitrix\Sale\Order::create). Re‑run during testing.
4. Staging — full migration to test server. Verify integrity: product count, properties, URLs, filters.
5. Final migration & switching — delta import, DNS switch, monitoring.

Typical Migration Mistakes and How to Avoid Them

Each of these errors has caused loss of positions and clients.

• Loss of URLs without redirects — the most destructive mistake. /product/123 instead of /catalog/item-name.html — without 301 this means mass 404s and traffic collapse. We auto‑generate the map and verify every redirect after switching.
• Content duplication — one product accessible with and without www, via HTTP and HTTPS, with GET filter parameters → five URLs instead of one. SEO weight dilutes. Set up canonical, 301 for variants, robots.txt with Disallow for parameters.
• Broken images — absolute URLs in content (src="https://old-site.ru/img/photo.jpg"), quality loss during compression. Replace with relative paths, transfer preserving structure, check HTTP 200 for each file.
• Loss of meta tags and microdata — title, description, Schema.org may not transfer. Do full mapping and verify on staging.
• Broken forms and integrations — changed IDs, API keys, webhooks. Compile integration register before start and test each after.
• Mobile version — old m.site.ru → responsive Bitrix. Without mobile URL redirect → 404 for mobile users. Include in redirect map.

Timelines and Cost Savings

Businesses typically save $3,000–$8,000 annually after migration — no old CMS license fees, reduced plugin and hosting costs. Annual hosting savings alone can reach $1,200. Add the affordable licensing cost of 1C‑Bitrix — it pays off quickly.
