Most enterprise migrations start 6+ months behind schedule. Yours doesn't have to.
This guide is for VPs of IT, data architects, and migration leads at companies moving data from Siebel CRM to Salesforce — whether you're scoping, planning, or mid-program.
Siebel CRM uses a highly normalized on-premise relational model with extension columns (ATTRIB_01 through ATTRIB_50), multi-value groups for many-to-many relationships, and decades of accumulated customizations, while Salesforce uses a cloud-native object model with explicit custom fields and junction objects. Mine reads Siebel's repository metadata to decode extension columns into meaningful Salesforce field mappings.

How Mine automates your Siebel CRM to Salesforce migration
Mine reads Siebel's repository metadata to decode extension columns — mapping ATTRIB_01 through X_CUSTOM_50 to meaningful Salesforce custom fields based on the business component configuration, not just the generic column names.
Multi-value groups and intersection tables are automatically profiled and mapped to Salesforce junction objects or native relationships (AccountContactRelation) — preserving roles, primary flags, and relationship dates.
Mine auto-maps Siebel Service Requests to Salesforce Cases with status translation, priority mapping, and activity history preservation — including escalation paths and resolution codes.
Siebel's picklist (LOV) values are extracted from the repository and aligned with Salesforce picklist values — flagging mismatches and generating value mapping tables for each field.

Common challenges migrating from Siebel CRM to Salesforce
Siebel extension columns to Salesforce custom fields
Siebel uses generic extension columns (ATTRIB_01 through ATTRIB_50, X_CUSTOM_01 through X_CUSTOM_50) on base tables, with the column's meaning defined in configuration, not the schema. Salesforce uses explicitly named custom fields (Custom_Field__c). Mapping requires reading Siebel's repository metadata to understand what each extension column actually stores, then creating the corresponding Salesforce custom field.

Siebel uses multi-value groups (MVGs) to model many-to-many relationships — for example, a contact associated with multiple accounts. These are stored in intersection tables (S_PARTY_PER, S_CONTACT_BU). Salesforce uses junction objects or AccountContactRelation. The MVG-to-junction-object translation must preserve relationship attributes (roles, dates, primary flags).
Explore related migrations →Siebel Organization-based access control
Siebel segments data visibility by Organization (S_ORG_EXT), Position, and Responsibility. Salesforce uses Profiles, Roles, Sharing Rules, and OWD settings. The access control model translation isn't just a data migration issue — it affects which records should be visible to which users post-migration and requires parallel security design.
Explore related migrations →Service request and activity model differences
Siebel's Service Request (S_SRV_REQ) model with activities (S_EVT_ACT), action items, and resolution codes is deeply integrated with Siebel's assignment engine. Salesforce Cases use a different workflow with Case Teams, Entitlements, and Milestones. The activity and resolution history must be mapped to preserve service-level reporting continuity.

The cost of manual Siebel CRM to Salesforce migration
Traditional Siebel-to-Salesforce migrations are run by large consulting firms over 12–18 months using middleware tools like Informatica or Dell Boomi. The data mapping alone — across accounts, contacts, opportunities, service requests, activities, and custom objects — typically takes 3–4 months of manual analysis.
Frequently asked questions
In one enterprise migration, a single field mapping error in customer master data caused $100K in billing discrepancies that went undetected for 6 months.
Mine catches these issues before they reach production.
