Overview
REsimpli and Nutshell take fundamentally different approaches to CRM data organization. REsimpli uses a flat lead record model with extensive real estate–specific properties (property addresses, ARV, repair estimates, mortgage info) and bundles phone, SMS, and AI features directly into the platform. Nutshell uses a three-entity model (Person, Company, Lead, Deal) with no native real estate fields and separates phone and SMS as add-on modules. FlitStack AI maps every REsimpli contact, company, deal, and standard activity to Nutshell's equivalent objects. Real estate custom properties migrate as custom fields on Nutshell Person and Deal records. REsimpli drip campaigns, SMS sequences, and AI agents (Speed-to-Lead, VoiceFollow, CallAnswer) have no Nutshell equivalent and must be rebuilt manually after migration. We use REsimpli's API to export records, transform property and contact data, and load into Nutshell via its REST API, with a test-run-first, delta-pickup cutover. During the extraction phase, our system performs a comprehensive schema audit to identify all custom fields, drip campaign memberships, and skip tracing data before generating the target mapping for your migration.
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 REsimpli 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.
REsimpli
Lead / Contact
Nutshell
Person (Lead)
1:1REsimpli's lead record maps directly to Nutshell Person (treated as a Lead). Name, email, phone, address, and title transfer as standard Person fields. Real estate property data embedded in the lead record migrates to custom fields on the Person record.
REsimpli
Property / Company
Nutshell
Company
1:1REsimpli's property record (when stored as a company-level entry) maps to Nutshell Company. Business name, website, industry, and address transfer as standard Company fields. Nutshell does not have a native property record — property address, ARV, and repair estimate fields migrate as custom fields on the related Deal or Person.
REsimpli
Deal
Nutshell
Deal
1:1REsimpli deal name, amount, stage, close date, and owner map directly to Nutshell Deal fields. Deal owner resolves by email match against Nutshell users. Pipeline and stage names map value-by-value — if stage names differ between REsimpli and Nutshell, a mapping table is applied during migration.
REsimpli
Pipeline
Nutshell
Pipeline
1:1REsimpli deal pipelines map 1:1 to Nutshell Pipelines. Each pipeline name in REsimpli becomes a named Pipeline in Nutshell, and its stages become the Nutshell pipeline's stage list in the same order. If REsimpli contains multiple pipelines, each one is replicated as a separate Pipeline object in Nutshell, preserving the original stage names and sequence. Stage-level probabilities and forecast categories are inherited from the Nutshell pipeline configuration once created.
REsimpli
Activity (Call, Email, Meeting, Note)
Nutshell
Activity
1:1REsimpli call logs, emails, meetings, and notes migrate as Nutshell Activities, preserving the original timestamp, owner, and linked Person/Company reference. Nutshell Activities display in the Person's activity feed and on the timeline. Each activity type maps to the corresponding Nutshell Activity Type value, and the activity subject becomes the Description field. Email bodies are attached where the source format is supported, maintaining a communication history in the destination system.
REsimpli
Owner / Agent
Nutshell
User
1:1REsimpli owner and agent records are resolved by email match against Nutshell Users. Unmatched owners are flagged before migration and assigned to a fallback Nutshell user or remain as a custom field on the migrated record for manual reassignment. This resolution step ensures that deal and person ownership is preserved, maintaining accountability and allowing the activity feed to correctly attribute actions to team members.
REsimpli
Custom Property — Property Address
Nutshell
Custom Field on Person / Deal
1:1REsimpli stores property address data within the lead record. Since Nutshell has no native property-address field on Person, we create custom text fields (Property_Address__c) and map the REsimpli address values during import. The field must exist in Nutshell before the import run.
REsimpli
Custom Property — ARV / After Repair Value
Nutshell
Custom Field on Deal
1:1ARV (After Repair Value) migrates to a custom currency or number field on Nutshell Deal (ARV__c). Currency format is preserved from REsimpli and re-formatted to Nutshell's expected decimal format during the transform step. The ARV field is placed on the Deal object because it represents the potential sale value of a property after renovations, aligning with deal-centric tracking in Nutshell.
REsimpli
Custom Property — Estimated Repairs
Nutshell
Custom Field on Deal
1:1Estimated repair costs migrate to a custom currency field on Nutshell Deal (Estimated_Repairs__c). Blank values in REsimpli are mapped to null and display as empty in Nutshell. This field captures the projected renovation costs associated with a property deal, allowing teams to calculate potential profit margins by comparing the estimated repairs against the ARV. The currency format matches the regional settings configured in your Nutshell account.
REsimpli
Custom Property — Mortgage Info
Nutshell
Custom Field on Person / Deal
1:1Mortgage-related fields (existing loan amount, interest rate, payoff amount) migrate to custom currency or number fields on the Person or Deal. The target object depends on whether REsimpli stores mortgage info at the contact or deal level. If stored at the deal level, fields appear on the Nutshell Deal; if at the contact level, they appear on the Person record. These fields help investors evaluate financing options.
REsimpli
Drip Campaign Membership
Nutshell
Custom Field on Person
1:1REsimpli drip campaign enrollment and status have no Nutshell equivalent. We preserve the campaign name and enrollment date as a custom multi-line text field (Drip_Campaign_History__c) on the Person record for reference. Sequences must be rebuilt in Nutshell's email sequence tool post-migration.
REsimpli
Skip Tracing Data
Nutshell
Custom Field on Person
1:1REsimpli's skip tracing results (found phone numbers, email addresses, alternate contacts) migrate as custom fields on the Person record (SkipTrace_Phone__c, SkipTrace_Email__c). Since skip tracing is a REsimpli-specific feature, no native Nutshell equivalent exists. The skip trace data appears as reference fields on the Person, allowing teams to view additional contact information. This preserves valuable research data even though no automated workflow will trigger from these fields.

Migration approach
Extract REsimpli records via API with full schema audit
FlitStack AI connects to your REsimpli account via API using scoped read access. We pull all Person, Company, Deal, Pipeline, Activity, and custom property records in a single extraction pass, capturing field names, data types, and sample values. This audit identifies the full inventory of real estate custom fields (ARV, repairs, mortgage data), drip campaign membership records, and skip-tracing data. The output is a data-dictionary document showing every REsimpli field and its target Nutshell mapping before any data moves.
Design Nutshell custom field schema and owner resolution map
Based on the REsimpli audit, FlitStack AI generates a custom field creation plan for Nutshell: a list of field names, types (text, currency, number, date, multiline text), and target objects (Person or Deal) for every REsimpli real estate property field. We simultaneously run the owner resolution map — matching REsimpli agent emails to Nutshell Users and flagging any unmatched owners. You or your Nutshell admin creates the custom fields in Nutshell's Setup tab during this window. No data is written during this step.
Run a test migration with field-level diff on a representative sample
A sample slice of 100–300 records (covering contacts, companies, deals, and activities with a mix of populated and blank custom fields) migrates into Nutshell first. FlitStack AI generates a field-level diff comparing source values against the Nutshell destination for every mapped field. You review the diff to confirm drip campaign history display, property address field placement, owner resolution, and stage mapping before committing the full run. This is the last chance to adjust value mappings or add missing custom fields without touching production data.
Execute full migration with delta-pickup window and audit log
All REsimpli records migrate to Nutshell using the validated field mapping. A delta-pickup window of 24–48 hours opens simultaneously: any REsimpli records created or modified during the migration run are captured and synced to Nutshell before final cutover. Every operation — record created, field mapped, owner resolved, custom field populated — is written to an audit log. If reconciliation reveals a mismatch, FlitStack AI provides a targeted re-migration of the affected records without touching the entire dataset. One-click rollback reverts Nutshell to the pre-migration state if reconciliation fails.
Deliver rebuild reference package for drip campaigns, SMS sequences, and AI agents
Since workflows, drip campaigns, SMS sequences, and AI agent configurations cannot migrate, FlitStack AI delivers a rebuild reference package: a structured export of all REsimpli drip campaign names, enrollment counts, sequence step definitions, and AI agent trigger rules. Your team uses this as a blueprint to recreate sequences in Nutshell's email sequence builder (Pro+ tier) and to configure a third-party SMS or AI telephony tool if needed. The rebuild reference is delivered alongside the audit log so both data migration completion and workflow rebuild planning can proceed in parallel.
