Upgrading from 1C-Bitrix Small Business to Business Edition
Upgrading from 1C-Bitrix Small Business to Business Edition
The "Business" edition is the level where the platform transitions from "it works" to "it works and scales." The upgrade from "Small Business" is typically triggered by one of three reasons: multisite mode is needed, comprehensive analytics and marketing tools are required, or performance demands have grown and a cluster has become necessary.
What the "Business" Edition Adds
Multisite. "Business" allows running multiple sites under a single license with a unified admin panel. This is not just a convenience — it is a cost saving: no need to purchase separate licenses for each regional subdomain or landing page.
Extended marketing. The sale module in "Business" includes triggered mailings, customer segmentation, extended discount rules with a cumulative system, and loyalty programs. In "Small Business" this is absent or heavily limited.
Sales analytics. Extended order reports, ABC customer analysis, a sales funnel within the CMS (not to be confused with Bitrix24 CRM) — available in "Business."
Web cluster. The ability to operate in a clustered configuration: multiple web servers, a load balancer, distributed session storage. In "Small Business" — single server only.
Task and business process management (tasks, bizproc) — extended functionality for automating internal company processes within the CMS.
Analysis Before the Upgrade
Upgrading to "Business" is not simply swapping a key. Preliminary analysis is required:
Audit of the current architecture. If the site has grown organically and somewhat chaotically, clarify before upgrading: which custom solutions were built "because the needed functionality was not in Small Business" — some of them can be replaced by standard "Business" tools.
Multisite: strategy. If the goal of the upgrade is multiple sites, define the architecture: a unified template with different settings, or different templates on one core, or regionally mirrored sites. This is designed before the upgrade, not after.
Marketing data. When activating extended marketing in "Business," discount rules and customer segments must be migrated or recreated — they are not automatically converted from the simplified "Small Business" model.
Upgrade Process
-
License upgrade. Via the 1C-Bitrix personal account or through a partner — pay the price difference.
-
Key update and module installation. New modules are installed through the Update System.
-
Multisite configuration (if needed). Creating new sites in "Settings → Sites." Configuring languages, templates, domains. Each site has its own section map.
-
Analytics and marketing setup. Creating customer segments, configuring loyalty programs, migrating discount rules.
-
Testing. Full verification of the main site and all new sites in multisite mode.
Case Study: Upgrade for a Network of Regional Offices
Client — a distributor of electrical equipment. Main site on "Small Business," 5 regional subdomains — on separate Bitrix instances with separate licenses. Total: 5 "Small Business" licenses plus a great deal of manual content synchronization.
Task: upgrade to "Business" with a unified multisite architecture.
Work:
- Upgraded one license to "Business"
- Deployed 5 regional sites on one core with a shared catalog and regional pricing (via price types linked to the site)
- Configured a shared news infoblock with publication to specific sites via the
SITE_IDparameter - Configured regional phone numbers and addresses via
SITE_ID-dependent component parameters - Migrated SEO settings from the regional sites
Result: one admin panel instead of six, content updated once and published to the right sites, licensing costs reduced.
Timeline
Basic upgrade with one additional site configured — 5–10 business days. Multisite architecture with multiple regions and data migration — 15–30 business days.
