CRM migration
Field-level mapping, validation, and rollback between Nurture and Nutshell. We move data and schema; workflows are rebuilt natively in Nutshell.

Overview
Moving from Nurture to Nutshell is a lateral migration between two small-team CRMs with different underlying object models and pricing structures. Nurture uses a flat-rate subscription with per-usage charges for calls, SMS, and emails; Nutshell charges per-seat with unlimited contacts and native email included. We reconcile the pricing model during scoping, map Nurture's Activities and Tasks into Nutshell's unified activity system, and preserve any custom field values as typed Nutshell custom fields. Workflows, automated sequences, and built-in calling plans do not migrate; we deliver a written inventory of any active automations and usage-based service configurations requiring rebuild or re-subscription in Nutshell. The migration typically completes in two to four weeks for accounts with fewer than 10,000 records.
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 Nurture 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.
Nurture
Contact
Nutshell
Person
1:1Nurture Contact records map directly to Nutshell Person. We map first_name, last_name, email, phone, and any custom field values to their Nutshell equivalents. If Nurture stores a combined name field, we split it into first_name and last_name during the transform. Person records are inserted before any related Deal records because Nutshell Deals carry a Person lookup.
Nurture
Company
Nutshell
Company
1:1Nurture Company records map directly to Nutshell Company. The domain name stored in Nurture becomes the Website field in Nutshell and serves as the deduplication key during import. Company records are inserted before Person records so that the Person-to-Company association is satisfied at the moment of Person insert.
Nurture
Deal
Nutshell
Deal
1:1Nurture Deal records map to Nutshell Deal. The deal stage maps to Nutshell stage via a configurable stage name translation table we build during scoping. Pipeline assignment from Nurture maps to a Nutshell Pipeline or Record Type that we configure before migration. Closed-won and closed-lost reasons from Nurture custom fields map to Nutshell custom text fields.
Nurture
Activity
Nutshell
Task
1:1Nurture Activity records (calls, emails, meetings, notes) map to Nutshell Task with TaskSubtype set to Call, Email, or Event based on the activity type. Activity timestamps preserve as Task ActivityDate. Call duration from Nurture migrates to a custom Nutshell field for call duration in seconds. Email body content migrates to the Task description field. This mapping is 1:1 at the record level but consolidated into a single Nutshell object type.
Nurture
Task
Nutshell
Task
1:1Nurture Task records map directly to Nutshell Task. Status, Priority, and ActivityDate preserve directly. Task assignment resolves by matching Nurture owner email to a Nutshell User record.
Nurture
Custom Field (all objects)
Nutshell
Custom Field (Nutshell typed)
lossyNurture custom field values map to Nutshell custom fields of the matching data type. Nutshell supports Text (max 225 characters), Long Text, Currency, and Date for custom fields on Person, Company, and Lead objects. If a Nurture custom field type does not have a direct Nutshell equivalent, we map it to a Text field and note the type difference in the migration manifest. We pre-create all required Nutshell custom fields via the API before any data import begins.
Nurture
Owner
Nutshell
User
1:1Nurture Owner records (assigned to Contacts, Companies, and Deals) map to Nutshell User by email match. We extract every distinct owner email referenced in the migration scope and resolve against the destination Nutshell workspace. Any owner without a matching Nutshell User is flagged in a reconciliation queue for the customer to provision before record import resumes.
Nurture
Lead
Nutshell
Lead
1:1If Nurture maintains a separate Lead object distinct from Contact, it maps to Nutshell Lead. Lead status values translate via a configurable status map we build during scoping. Lead source and any scoring values from Nurture custom fields migrate to equivalent Nutshell custom fields.

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.
Nurture gotchas
Conflicting public guidance on API availability
Trigger-rule and journey logic is not portable
RSS-to-Email campaigns depend on live feed availability
Nutshell gotchas
Contact tier limits enforced on import
No bulk API endpoint requires paginated extraction
Email sequences not exportable via API

Migration approach
Discovery and Nurture audit
We audit the source Nurture portal for all standard objects (Contacts, Companies, Deals, Activities, Tasks), custom field definitions, active user count, owner assignments, and any active workflow configurations. We capture the current usage-based service billing summary (average call minutes, SMS count, email volume over the past three months) so the customer has a reference point for Nurture account cancellation. The discovery output is a written scope confirming record counts, custom field inventory, and any workflow or automation features that require separate rebuild documentation.
Nutshell workspace preparation
We set up the destination Nutshell workspace. This includes provisioning custom fields on Person, Company, Lead, and Deal objects to receive any mapped custom values from Nurture, configuring the Deal pipeline and stage names to match the Nurture setup as closely as possible, and creating a Nutshell User record for each Nurture Owner by email. We validate that all required Nutshell custom fields exist with the correct data types before any data import begins.
Sandbox migration and reconciliation
We run a test migration into a Nutshell staging environment using a representative sample of production data (typically 10-15% of total records). The customer reviews 25-50 spot-checked records against the Nurture source and validates that Person records are correctly linked to Company, Deal records are linked to the correct Person, and activity timestamps are preserved. Any mapping corrections happen in this phase. We do not proceed to production until the customer signs off on the sandbox results.
Owner reconciliation and User provisioning
We extract every distinct Nurture Owner email from Contacts, Companies, and Deals and match against Nutshell User records by email. Any owner without a matching Nutshell User goes to a reconciliation queue for the customer's admin to provision. OwnerId references must be resolvable before record import because Nutshell requires a valid owner on Deal and Person records.
Production migration in dependency order
We run production migration in record-dependency order: Nutshell Users (manual, validated), Companies (from Nurture Companies), Persons (with CompanyId resolved), Deals (with PersonId and OwnerId resolved), and Activities/Tasks (consolidated into Nutshell Task via Bulk API with TaskSubtype set per activity type). Each phase emits a row-count reconciliation report before the next phase begins. Custom field values insert in the same pass as their parent object.
Cutover, validation, and workflow handoff
We freeze Nurture writes during cutover and run a final delta migration for any records modified during the migration window. We enable Nutshell as the system of record once delta validation confirms zero new records pending. We deliver the Nurture workflow inventory document to the customer's admin with recommended Nutshell equivalents. We offer a one-week hypercare window to resolve any reconciliation issues raised by the team. We do not rebuild Nurture workflows as Nutshell automations inside the migration scope; that is a separate engagement.
