Overview
The migration also maps Gearbox custom properties—service type, cost, and odometer reading—into Nutshell custom fields that appear on the corresponding Deal, Task, or Person record. All original timestamps, including creation date, last‑modified, and completion date, are preserved in custom datetime fields to keep the service history intact. Gearbox equipment records, which hold vehicle ID, license plate, VIN, and operational status, translate to custom fields on the Person record that represents the vehicle’s primary driver or fleet manager. The process runs in read‑only mode on Gearbox, allowing your team to continue logging work orders during cutover. A delta‑pickup phase captures any new or changed records after the initial load, and a reconciliation report verifies source‑destination totals before the go‑live.
Every standard and custom field arrives verified.
AI proposes the map; you confirm before any record moves.
Parent–child, lookups, and ownership stay linked.
Calls, emails, meetings — with original timestamps.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Gearbox object lands in Nutshell, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Gearbox
Person
Nutshell
Person
1:1Gearbox Person maps directly to Nutshell Person. Email, phone, name, and address fields transfer 1:1. Gearbox fleet_role and role_specialty have no native Nutshell equivalent — they become custom text fields on the Person record so the role context is not lost in migration.
Gearbox
Company
Nutshell
Company
1:1Gearbox Company maps directly to Nutshell Company. Company name, address, industry, and employee count transfer as-is. Multi-location companies in Gearbox collapse to a single Nutshell Company record; secondary addresses are preserved as a custom text field on the Company record.
Gearbox
Lead
Nutshell
Lead
1:1Gearbox Lead maps directly to Nutshell Lead. Lead status and source fields that have no native Nutshell equivalent are stored as custom text fields on the Nutshell Lead. Gearbox lead scores migrate as a custom numeric field (Lead_Score__c) so sales priority is preserved.
Gearbox
Work Order
Nutshell
Deal
1:1Gearbox Work_Order becomes a Nutshell Deal. The original Work_Order_ID is stored as a custom field (Work_Order_ID__c) on the Nutshell Deal for traceability. Service type, cost, and vehicle ID are preserved as custom fields on the Deal. Contact and company links transfer as the Deal's primary person and company associations.
Gearbox
Maintenance Schedule
Nutshell
Task
1:1Gearbox Maintenance_Schedule becomes a Nutshell Task. The scheduled_date maps to the Nutshell Task due date; completion status maps to the Task status field. Vehicle_ID and Service_Type are stored as custom text fields on the Nutshell Task. Unassigned maintenance schedules route to a flagged fallback Nutshell user identified before migration runs.
Gearbox
Equipment
Nutshell
Custom fields on Person
1:1Gearbox Equipment has no direct Nutshell equivalent since Nutshell does not have a native asset or equipment object. Asset_ID, License_Plate, VIN, and Odometer_Reading transfer as custom fields on the Nutshell Person record linked to the equipment's assigned contact. Vehicles without a primary contact are attached to a default fallback Person record flagged before migration.
Gearbox
Activity
Nutshell
Task
1:1Gearbox Activity records — calls, emails, meetings, and tasks — map directly to Nutshell Tasks. Activity type maps to the Task type field. Original timestamp, assigned contact, and duration transfer as-is so the service history timeline is preserved in Nutshell.
Gearbox
Note
Nutshell
Note
1:1Gearbox Note body with rich text content migrates as a Nutshell Note. Notes attached to People, Companies, or Work Orders are re-linked to the corresponding Nutshell Person or Company record. Original create date is preserved as a custom datetime field on the Nutshell Note.
Gearbox
File / Attachment
Nutshell
File
1:1Gearbox file attachments are downloaded and re-uploaded to Nutshell's file storage. Files are associated with the corresponding migrated record (Person, Company, or Deal) by matching the original file name and parent record ID. Large files are chunked to stay within Nutshell file size limits.
Gearbox
Role / Association
Nutshell
Role field on Person
1:1Gearbox role labels (Driver, Fleet Manager, Technician) map to Nutshell's native Role field on Person using value-by-value mapping. Gearbox role_specialty free-text values with no standard equivalent are stored as a custom text field on the Nutshell Person rather than forcing them into the Role dropdown.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Gearbox gotchas
Gearbox edition tiers gate API access
Work order history links assets by ID, not UUID
Preventive maintenance schedules use interval math that varies by platform
Contractor records may be soft-deleted in Gearbox
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API
Foundation plan disables key sales features

Migration approach
Extract Gearbox data via API in scoped batches
FlitStack AI connects to Gearbox using scoped read-only API credentials. We export People, Companies, Leads, Work Orders, Maintenance Schedules, Equipment, Activities, Notes, and Files in structured batches sized to respect Gearbox's API rate limits. Each batch is validated for schema completeness before the next batch starts. The export includes original timestamps, assigned owners, and cross-object IDs for relationship resolution in the next step. A migration audit log begins recording every operation from the first extract onward.
Create Nutshell custom fields for fleet-specific data
Before data loads into Nutshell, we create the custom fields identified in the mapping plan — Vehicle_ID__c, Odometer_Reading__c, Work_Order_ID__c, Service_Type__c, Equipment_ID__c, and others flagged in the object mapping. Nutshell's field creation UI supports text, number, pick-list, and date types. We deliver a field-creation checklist so your Nutshell admin can pre-create the fields or grant FlitStack API access to create them programmatically. Validation rules are configured at this stage to catch missing required fields on first load.
Run a sample migration with field-level diff
A representative slice of records — typically 100–500 spanning people, companies, work orders, maintenance schedules, and activities — migrates into Nutshell first. We generate a field-level diff comparing source values against the resulting Nutshell records so you can verify Gearbox-to-Nutshell field mapping before the full run commits. Work-order status mapping, custom field population, owner resolution, and equipment attachment are the primary verification points at this stage.
Execute full migration with delta-pickup window
The full dataset loads into Nutshell via the Nutshell JSON-RPC API. Gearbox remains fully accessible to your team during the migration — we use scoped read-only access so operations in Gearbox are uninterrupted. A delta-pickup window (typically 24–48 hours) runs after the full load, capturing any Gearbox records created or modified during the cutover period. The audit log records every operation, and a reconciliation report compares Gearbox source counts against Nutshell destination counts for each object type.
Validate reconciliation and deliver rollback package
Post-migration, we run a record-count reconciliation across all object types and spot-check field values against the Gearbox source. Any records with validation failures are flagged and corrected in a targeted re-migration pass. We deliver a rollback package — a complete export of the migrated Nutshell dataset — that can be loaded back in if your team determines the migration results require a reset. The rollback package is retained for 14 days post-migration.
