Overview
Apollo ERP organizes data around contacts (people), organizations (companies), and deals with a heavy emphasis on enrichment and sequence tooling. Nutshell uses a unified person model where people and companies are top-level entities, leads are tracked separately, and deals sit as a pipeline layer above them. The structural difference that creates the most migration work is Apollo's N:1 contact-to-organization model — where one contact belongs to one organization — versus Nutshell's contact-to-company lookup that requires a parent company record to exist before a person can link to it. FlitStack AI sequences the migration in dependency order: organizations first (because people depend on them via the company link), then people with email-based owner matching, then deals with stage mapping, then activities attached to their parent person records. We extract Apollo's enrichment data (employee counts, revenue signals) as static custom fields in Nutshell since Nutshell does not have a live enrichment layer. Custom fields defined in Apollo Settings map to Nutshell custom fields on the person or company object. Activity timestamps, task subjects, and call/emails are preserved as Nutshell tasks with original creation dates and assigned owners. We use Apollo's REST API with pagination for extraction and Nutshell's JSON-RPC API for import, with retry logic on rate-limited endpoints. Workflows, sequences, and enrichment settings do not migrate — we export definitions for manual rebuild in Nutshell's automation tools. FlitStack AI runs scoped read access throughout so your team keeps working in Apollo during the migration window, with a delta-pickup window capturing any in-flight changes before go-live.

Object mapping
Each row shows how a Apollo ERP 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.
Apollo ERP
Contact (person)
Nutshell
Person
1:1Apollo contacts map directly to Nutshell people records. The person name, email, phone, and job title carry over as standard fields. The company link requires a pre-existing Nutshell company record — we create companies first so foreign-key resolution is clean.
Apollo ERP
Organization (company)
Nutshell
Company
1:1Apollo organizations map 1:1 to Nutshell companies. Company name, domain, industry, employee count, and annual revenue map to their Nutshell equivalents. Apollo's industry pick-list values are mapped to Nutshell's industry pick-list per the value map created during discovery. Where Apollo stores numeric revenue as a formatted string, we parse it to a numeric value for Nutshell's revenue field. All organization records migrate in the organizations-first step to ensure they exist before any dependent person records link to them via the company lookup.
Apollo ERP
Deal
Nutshell
Deal
1:1Apollo deals map to Nutshell deals with pipeline stage mapping. Apollo stage names map to Nutshell stage names per the stage-value map created during discovery. Deal amount, close date, and owner are carried forward; owner is resolved by email match to Nutshell users.
Apollo ERP
Enrichment data (company)
Nutshell
Company custom fields
1:1Apollo's company-level enrichment signals (employee count ranges, revenue tiers, technology stack) have no native Nutshell equivalent. We create a set of company custom fields in Nutshell and populate them with the last-known enrichment values from Apollo — treated as static reference data since Nutshell does not refresh enrichment.
Apollo ERP
Enrichment data (contact)
Nutshell
Person custom fields
1:1Apollo contact-level enrichment data (seniority, department, intent signals) has no direct Nutshell equivalent. We create person-level custom fields in Nutshell and populate them with Apollo's enrichment output, preserving the data for reference even though it will not be updated by Nutshell's native tools.
Apollo ERP
Custom field (string, number, date)
Nutshell
Person / Company / Deal custom fields
1:1Apollo custom fields defined in Settings > Objects, fields, stages map to identically typed custom fields in Nutshell. We create the destination custom field in Nutshell first, then map values during the migration run. Pick-list custom fields require value-by-value mapping if the Nutshell pick-list options differ from Apollo's.
Apollo ERP
Activity: Call / Email / Meeting
Nutshell
Task
1:1Apollo call logs, email records, and meeting logs become Nutshell tasks attached to the parent person record. Task type is set to Call, Email, or Meeting, subject carries the activity description, and the original creation timestamp is preserved in a custom datetime field on the task since Nutshell's CreatedDate reflects the import time.
Apollo ERP
Contact last_contacted_date
Nutshell
Person last_contacted custom field
1:1Apollo's computed last_contacted_date field has no native Nutshell equivalent. We create a Last_Contacted__c custom datetime field on the person object and populate it with Apollo's value so the last-contacted signal is visible in Nutshell without requiring activity reconstruction. This preserves the last-contacted intelligence your team relies on for follow-up prioritization, carrying forward the computed date as a static field rather than deriving it from activity records.
Apollo ERP
Contact without organization
Nutshell
Person (unlinked)
1:1Apollo contacts with no linked organization_id are valid and exported with null company. We migrate these as Nutshell people records with no company link, flagging them during mapping review so your team can decide whether to attach to an existing company or leave them unlinked.
Apollo ERP
User / Owner
Nutshell
User
1:1Apollo owner_id values are resolved by email match against Nutshell users. Unmatched owners are flagged before migration — your team either creates Nutshell user accounts or assigns records to a fallback owner. No record lands in Nutshell without a valid owner.
Apollo ERP
Sequence / Workflow
Nutshell
Not migratable
1:1Apollo sequences and workflow rules have no equivalent in Nutshell's automation model. We export the sequence definitions (step order, delay days, email templates) as a structured reference document your team can use to rebuild sequences in Nutshell's personal email sequence tool.
Apollo ERP
Apollo data export backup
Nutshell
Source reference record
1:1Apollo does not provide a comprehensive all-objects export in a single file. We extract data via the REST API in paginated batches, preserving the export scope and original field values. The API extraction log serves as the source-of-truth reference for reconciliation after the Nutshell import completes.

Migration approach
Connect and audit Apollo data via scoped read access
FlitStack AI connects to your Apollo account using scoped API credentials with read-only access. We extract contacts, organizations, deals, and custom field definitions in paginated batches, preserving original field values and timestamps. We generate a data inventory showing record counts per object, custom field definitions, and owner distribution. This audit runs without touching your live Apollo data — your team continues working in Apollo throughout the extraction phase.
Deliver field mapping plan and stage configuration checklist
Based on the audit, we produce a field-mapping plan showing every Apollo field mapped to its Nutshell destination, including custom fields to be created, value mappings for pick-lists, and any fields with no Nutshell equivalent flagged for manual handling. We include a Nutshell configuration checklist: create pipeline stages, set up custom fields on person and company objects, and configure any required pick-list values. Your Nutshell admin completes this checklist before the sample migration runs.
Migrate companies first, then people, then deals
We sequence the migration to satisfy Nutshell's foreign-key constraints. Companies (organizations) migrate first so they exist before any person record that links to them. People (contacts) migrate second with owner resolution by email match to Nutshell users. Deals migrate third with stage values mapped per the stage-value map and linked to the newly created person and company records. Activities (calls, emails, meetings) migrate last, attached to their parent person records with original timestamps preserved in custom fields.
Run sample migration with field-level diff and reconcile
A representative slice of 100–500 records migrates first — covering a mix of contacts, companies, deals, and activities. We generate a field-level diff comparing source Apollo values to destination Nutshell values for every mapped field. You review the diff with our team, confirm pick-list value mappings, and approve the full migration scope. Any field mapping corrections are applied before the full run commits.
Execute full migration with delta-pickup and audit log
The full migration runs against Nutshell's JSON-RPC API using batched requests with retry logic on rate-limited endpoints. A delta-pickup window (typically 24–48 hours) captures any records created or modified in Apollo during the migration run. FlitStack AI provides an audit log of every record created, updated, or skipped with reason codes. One-click rollback is available if reconciliation fails. Post-migration, we deliver a reconciliation report comparing Apollo record counts to Nutshell record counts per object with a list of any records that did not land.
