Overview
Populate and Nutshell both use a contact-company-deal model, but they structure relationships and custom fields differently. Populate typically stores people with company associations and deal records tied to pipeline stages; Nutshell uses People for contacts, Companies for organizations, and Deals with customizable stage names. The migration extracts Populate records via API or export, maps each field to Nutshell's equivalents, and loads through Nutshell's JSON-RPC API or bulk import. Custom fields on People, Companies, and Leads require pre-creation in Nutshell before data lands. Workflows, email sequences, and automation logic do not migrate — these must be rebuilt in Nutshell using your exported Populate configurations as a reference. Nutshell's Enterprise plan supports custom fields on all record types, while lower tiers may restrict field counts. FlitStack AI sequences the migration so foreign keys resolve correctly: Companies first, then People with CompanyId links, then Deals with owner resolution by email match. A delta-pickup window captures any records modified during cutover.
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 Populate 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.
Populate
Person (Contact)
Nutshell
People
1:1Populate Person records map 1:1 to Nutshell People records. The Person's inline company name must be resolved: if a matching Nutshell Company exists, link via CompanyId; if not, create the Company first, then link. Nutshell People records require a Name field (full name or first+last).
Populate
Company (Organization)
Nutshell
Company
1:1Populate Company records map directly to Nutshell Company records. Nutshell Companies have standard fields for name, domain/website, address, phone, and industry, plus optional fields such as employee count and annual revenue. Parent-company hierarchies in Populate map to Nutshell's parent_company relationship if present. All fields are written via Nutshell's JSON-RPC API, and any missing optional fields default to empty without causing import errors.
Populate
Lead (Unconverted Prospect)
Nutshell
Lead
1:1Populate records with a lead/prospect status map to Nutshell Leads. Nutshell Leads have their own custom field support separate from People. If Populate stores leads as People with a status flag, the split into Nutshell Lead vs People happens during migration based on the status value.
Populate
Deal (Opportunity)
Nutshell
Deal
1:1Populate Deal records map to Nutshell Deals. Each Deal requires a linked CompanyId and optionally a linked PeopleId. Nutshell Deal stages are configurable per pipeline — stage names from Populate map to Nutshell stage values value-by-value. Deal amount, close date, and owner map directly.
Populate
Pipeline
Nutshell
Pipeline
1:1Populate pipeline configuration maps to Nutshell Pipeline configuration. If Populate supports multiple pipelines, each becomes a separate Nutshell Pipeline. Pipeline stage names in Populate must map to Nutshell stage values within each Pipeline — this requires a value-mapping table per pipeline.
Populate
Activity (Call, Email, Meeting, Note)
Nutshell
Activity / Note
1:1Populate activity records split into Nutshell Activities (calls, emails, meetings with timestamps and owners) and Notes (text content). Nutshell stores activities as part of the record timeline; Notes are separate objects linked to People, Companies, or Deals. Original timestamps and owner assignments are preserved.
Populate
Custom Field (Person)
Nutshell
Custom Field (People)
1:1Populate custom fields on Person records require pre-creation in Nutshell as custom fields on the People object before migration. Field types (text, number, date, pick-list) must match Nutshell's supported types. Once created in Nutshell, data migrates directly into the custom field.
Populate
Custom Field (Company)
Nutshell
Custom Field (Company)
1:1Populate custom fields on Company records migrate to Nutshell Company custom fields. These must be created in Nutshell before data loads. Nutshell's field type constraints apply — pick-list fields in Populate map to Nutshell 'choices' type with the same options listed.
Populate
Custom Field (Lead)
Nutshell
Custom Field (Lead)
1:1Populate custom fields on Lead records migrate to Nutshell Lead custom fields. Lead-specific fields (e.g., source, qualification status) map to custom fields in Nutshell. All custom fields on Leads must exist in Nutshell before the migration batch runs. If any custom fields are missing, FlitStack AI will pause and prompt the admin to create them prior to the run.
Populate
Owner (User)
Nutshell
User
1:1Populate owner/user records resolve by email match to Nutshell Users. If a Populate owner email matches an existing Nutshell User email, the Deal or Person owner maps to that User. Unmatched owners are flagged before migration — teams either invite them to Nutshell or assign records to a fallback owner.
Populate
Attachment / File
Nutshell
File
1:1Populate file attachments on records (People, Company, Deal) are downloaded and re-uploaded to Nutshell as Files linked to the parent record. Nutshell stores files with name, content type, and size. Large files may be subject to Nutshell's file size limits.

Migration approach
Audit Populate data volume and field inventory
FlitStack AI connects to Populate via API or export file to inventory all People, Companies, Leads, Deals, Activities, Notes, and custom fields. We document field types, pick-list values, and ownership assignments. This inventory determines the Nutshell plan tier needed, the custom field creation list, and any value-mapping tables required. A pre-migration report is delivered for your review before any schema changes are made in Nutshell.
Pre-create Nutshell custom fields and pipelines
Based on the Populate field inventory, FlitStack AI generates a setup checklist for your Nutshell admin (or executes it via API if granted access). Custom fields on People, Companies, and Leads are created with matching types. Pipelines and stage names from Populate are configured in Nutshell. This step ensures the destination schema is ready before data lands, avoiding import failures due to missing fields.
Resolve owners and create Companies before People and Leads
Nutshell requires Companies to exist before People can link via CompanyId, and requires Users to exist before Deals can assign an owner. FlitStack AI sequences the migration: (1) resolve Populate owner emails to Nutshell Users by match, flagging unmatched owners; (2) load Companies; (3) load People with CompanyId links; (4) load Leads; (5) load Deals with owner and CompanyId assignments. Inline company names on People are extracted, deduplicated, and loaded as Companies in the first batch.
Run sample migration with field-level verification
A representative slice of Populate records — typically 100–500 records spanning all object types — migrates to a Nutshell staging environment or sandbox. FlitStack AI generates a field-level diff comparing source values to destination values for every mapped field. You verify that stage mappings, owner resolution, custom field data, and association links appear correct. Approval of the sample unlocks the full migration run.
Execute full migration with delta-pickup cutover window
The full Populate dataset loads into Nutshell through the configured object sequence. A delta-pickup window of 24–48 hours runs concurrently, capturing any records created or modified in Populate during the migration window. Audit logging records every operation. If reconciliation identifies gaps, FlitStack AI provides a correction batch. One-click rollback reverts Nutshell to pre-migration state if critical issues surface. During the load, FlitStack AI monitors API response times and retries transient failures automatically to maintain data integrity.
Deliver migration report and rebuild reference package
FlitStack AI delivers a final migration report showing record counts, error rates, and mapping summaries for each object. A separate rebuild reference package includes exported Populate workflow definitions, sequence configurations, and custom field lists formatted for Nutshell admin use. Post-migration support is available for 5 business days to address data issues or adjustment requests. The report is delivered as a PDF summary and a JSON detail file, and FlitStack AI can schedule a live walkthrough call to walk through the results with your team.
