Overview
ServiceNow Field Service Management runs on a table-based data model where Work Orders (wm_order), Work Order Tasks (wm_task), Locations, and Agent profiles are cross-referenced via sys_id foreign keys. Twenty CRM uses a relational model built around People, Companies, Opportunities, Tasks, and Notes — with custom objects available on Pro and Organization tiers. These models diverge structurally: ServiceNow's state flows, dispatcher assignment logic, shift scheduling, and SLA policy tables have no native Twenty equivalent and must be rebuilt post-migration. FlitStack AI extracts Work Order headers and line-item tasks as separate passes to respect Twenty's import ordering (Companies first, then People, then Opportunities). Locations are mapped to Company address fields or held as custom address fields when the location is a service site rather than a customer account. Agent profiles (sys_user records with FSM roles) become People records in Twenty, with FSM role designations stored as a custom select field. Attachments are downloaded and re-loaded as Notes. Custom extended tables — a common FSM configuration — are mapped to Twenty custom objects or custom fields per table. The migration extracts from ServiceNow via REST API or bulk export, transforms values through mapping scripts, and loads into Twenty via CSV import or API. Automations including state flows, assignment rules, and SLA policies are outside migration scope and must be rebuilt manually using Twenty's workflow builder and custom field logic.

Object mapping
Each row shows how a ServiceNow Field Service Management object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
ServiceNow Field Service Management
Work Order (wm_order)
Twenty CRM
Opportunity
1:1Work Order headers map to Twenty Opportunities. ServiceNow fields like short_description, priority, state, and assignment group translate to Twenty Opportunity fields plus custom fields for FSM-specific state values. The Work Order number is stored as a source reference field. These include FSM_State__c for status, Priority__c for severity, and Assignment_Group__c for team. The mapping script also resolves the location reference to a Company record, linking the Opportunity to the customer account.
ServiceNow Field Service Management
Work Order Task (wm_task)
Twenty CRM
Task
1:1Work Order Tasks map 1:1 to Twenty Tasks. Each task is linked to the parent Opportunity representing the Work Order. Skill requirements, shift windows, and task type are stored as custom fields on the Task record. These custom fields include Required_Skills__c for skills, Shift_Start__c and Shift_End__c for timing, and Task_Type__c for classification.
ServiceNow Field Service Management
Location (sys_documentation)
Twenty CRM
Company
1:1ServiceNow Locations (street address, city, state, postal code, country) map to Company address fields. When a Location represents a service site rather than a customer account, it is stored as a custom address field on the related Company record. The location's latitude and longitude are also captured in custom number fields for geographic reference.
ServiceNow Field Service Management
Agent / Field Technician (sys_user with FSM role)
Twenty CRM
People
1:1ServiceNow sys_user records assigned the FSM Agent role map to Twenty People records. Email, phone, first name, and last name migrate directly. The FSM role label (Agent, Dispatcher, Manager) is preserved as a custom select field on the People record.
ServiceNow Field Service Management
Dispatcher
Twenty CRM
People
1:1ServiceNow users with the Dispatcher FSM role map to Twenty People records. Dispatcher-specific columns like dispatch_center assignment are stored as custom fields. These People records can be assigned as Task owners in Twenty. During migration, the dispatch_center value is written to a custom text field named Dispatcher_Center__c, allowing managers to filter People by their assigned dispatch hub.
ServiceNow Field Service Management
Work Order Priority
Twenty CRM
Custom field on Opportunity
1:1ServiceNow priority values (1 Critical through 5 Low) are mapped to a custom Priority__c select field on the Twenty Opportunity. The value list is defined during workspace setup to match the source pick-list. Each priority level is represented as a distinct option, and a mapping script translates the numeric ServiceNow level to the corresponding label, preserving sort order for reporting and dashboards.
ServiceNow Field Service Management
Work Order State / State Flow
Twenty CRM
Custom field on Opportunity
1:1ServiceNow state flows govern Work Order status transitions (Open, Work In Progress, Pending, Closed Complete, etc.). Twenty has no state flow engine, so the current state is stored as a custom select field (FSM_State__c) on the Opportunity. State flow logic must be rebuilt in Twenty's workflow builder.
ServiceNow Field Service Management
Assignment Group / Dispatcher Assignment
Twenty CRM
Custom field on Opportunity or People
1:1ServiceNow assignment groups define which team or dispatcher owns a Work Order. These are mapped to a custom text or select field (Assignment_Group__c) on the Twenty Opportunity, referencing the group name from ServiceNow. If multiple groups exist, they can be stored as a multi-select field or split into separate records, depending on reporting needs. The mapping also captures any nested group hierarchy.
ServiceNow Field Service Management
Skill and Certification Requirements
Twenty CRM
Custom field on Task
1:1FSM skill requirements attached to Work Order Tasks are stored as custom multi-select or text fields (Required_Skills__c) on the Twenty Task record. These are informational in Twenty since skill-based routing logic must be rebuilt manually. During migration, the skill list is parsed from the source and written as a comma-separated string, preserving the original certification identifiers for future reference.
ServiceNow Field Service Management
Attachment / Work Order Attachment
Twenty CRM
Note
1:1ServiceNow attachments linked to Work Orders or Work Order Tasks are downloaded and re-loaded as Twenty Notes, linked to the corresponding Opportunity or Task record. File size limits and content types are validated before import. The migration script checks each attachment against Twenty's maximum file size and supported MIME types, converting unsupported formats if necessary and logging any skipped files for manual review.
ServiceNow Field Service Management
Custom FSM Extended Table (sn_fsm_* tables)
Twenty CRM
Custom Object or Custom Field
1:1ServiceNow FSM custom extended tables are evaluated individually. Tables with a simple structure map to Twenty custom fields on the Opportunity or Task. Tables with their own relationships require a Twenty custom object with a relation field back to the parent Opportunity.
ServiceNow Field Service Management
Shift and Schedule Window
Twenty CRM
Custom datetime fields on Task
1:1ServiceNow shift patterns and scheduling windows on Work Order Tasks are stored as custom datetime fields (Shift_Start__c, Shift_End__c) on the Twenty Task. Route optimization data is not portable and must be reconstructed manually in Twenty. The migration also captures any pre‑assigned travel buffers as a custom number field, which can be referenced for future scheduling decisions once a compatible tool is integrated.

Migration approach
Discover and profile ServiceNow FSM data structure
We connect to your ServiceNow instance via scoped REST API credentials and enumerate the wm_order, wm_task, and related tables. We document custom extended tables, state flow configurations, and assignment group structures. A data profile report identifies malformed dates, orphaned task references, and duplicate location records before we build the mapping plan. We also capture the list of sys_user records with FSM roles to map Agents and Dispatchers to Twenty People records.
Design Twenty workspace schema and custom field plan
Before data moves, we design the Twenty workspace schema — creating the custom fields needed for FSM-specific data (FSM_State__c, Priority__c, Required_Skills__c, FSM_Role__c, Assignment_Group__c) and any custom objects required for extended table migration. We deliver a field creation checklist so your Twenty admin can pre-provision the schema. We also define the mapping from ServiceNow state flow stages to the custom FSM_State__c select values so the value list is ready before records land.
Migrate in dependency order: Companies, People, Opportunities, Tasks, Notes
FlitStack AI executes five ordered passes. First, ServiceNow Locations are loaded as Twenty Companies with address fields. Second, ServiceNow sys_user records with FSM roles are loaded as Twenty People with FSM_Role__c set. Third, Work Order headers are loaded as Opportunities with state, priority, assignment, and location mapping resolved. Fourth, Work Order Tasks are loaded as Twenty Tasks linked to parent Opportunities. Fifth, ServiceNow attachments are downloaded and re-loaded as Notes. Each pass validates foreign keys before committing — unmatched agent emails are flagged for manual assignment or fallback to a default Twenty user.
Run sample migration with field-level diff
A representative slice — typically 200–500 records spanning Work Orders, Tasks, Locations, and Agents — migrates first. We generate a field-level diff comparing source ServiceNow values against the Twenty records. You verify that state values map correctly, priority ordering is preserved, task assignments resolve to the right Twenty People, and location addresses display correctly on the Company records. Any mapping corrections are scripted and applied before the full run. This step is critical for FSM migrations because the state flow gap requires explicit confirmation that current Work Order states are visible in Twenty.
Execute full migration and delta pickup
The full migration loads all remaining Work Orders, Tasks, Locations, Agents, and Attachments into Twenty. A delta-pickup window (typically 24–48 hours) captures any records created or modified in ServiceNow FSM during the cutover. All operations are logged to the FlitStack audit log. One-click rollback is available if reconciliation identifies mapping errors. After rollback is confirmed, your team can begin rebuilding ServiceNow state flow logic in Twenty's workflow builder using the exported FSM state transition documentation as a rebuild reference.
