Overview
Sierra Interactive models real estate leads, companies, and deals in a single CRM with IDX-website integration, saved listings tied to each contact, and Action Plans that sequence automated follow-ups. Nutshell consolidates these into People, Companies, Leads, and Deals with custom fields for People, Companies, and Leads, offering list, map, chart, and board pipeline views with per-contact pricing tiers. We migrate all standard Sierra Interactive objects via your REST API, map each field to its Nutshell equivalent, and create custom fields for saved listings, lead tags, lead sources, and action plan step descriptions. Action Plans require rebuild in Nutshell Tasks and automation sequences — we export the full action plan definition as a reference document your team can use to recreate logic in Nutshell's workflow builder. The migration uses scoped read access with a delta-pickup window during cutover so Sierra Interactive operations continue uninterrupted. During the delta window, any new or modified records are pulled from Sierra Interactive to ensure the Nutshell database mirrors the latest state at cutover, minimizing data loss and downtime.
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 Sierra Interactive 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.
Sierra Interactive
Lead
Nutshell
Person
1:1Sierra Interactive Lead maps directly to Nutshell Person for contacts that represent existing clients or qualified prospects. The name, email, phone, address, and job title fields transfer as-is. Nutshell Person requires a primary CompanyId — leads without a company association attach to a default 'Unassigned' company record.
Sierra Interactive
Lead (unqualified prospect)
Nutshell
Lead
1:1Sierra Interactive leads that have not yet been qualified route to Nutshell's Lead object. Nutshell Lead stores name, email, phone, and source. Once a lead converts, Nutshell's built-in lead-to-person conversion updates the Person record and closes the Lead at conversion.
Sierra Interactive
Company
Nutshell
Company
1:1Sierra Interactive company records (brokerages, real estate firms, property management companies) map to Nutshell Company with name, address, website, phone, and industry preserved. Parent-company hierarchies in Sierra map to Nutshell's Parent CompanyId field when present. Including ownership structure details and primary contact information.
Sierra Interactive
Deal
Nutshell
Deal
1:1Sierra Interactive deal records (transactions, listings, buyer/seller representation) map to Nutshell Deal with deal name, value, stage, expected close date, and owner preserved. Nutshell Deal requires a linked Person and Company — we resolve these lookups before inserting. And ensure accurate pipeline reporting.
Sierra Interactive
Action Plan
Nutshell
Task + Custom Field
1:1Sierra Interactive Action Plans sequence automated emails, texts, voicemails, and phone tasks per lead. Nutshell has no equivalent automation-sequencing construct. We export each action plan's steps as a JSON audit log saved in a Nutshell custom field (Action_Plan_Audit__c) on the Person record for manual rebuild reference.
Sierra Interactive
Saved Listing
Nutshell
Custom Field (Person)
1:1Sierra Interactive tracks saved properties per lead as property IDs with search criteria. Nutshell has no native saved-listings concept. We create a custom field (Saved_Listings__c) on Nutshell Person and serialize the property ID array as a JSON string for reference. Teams rebuild the search-context in Nutshell manually.
Sierra Interactive
Lead Tag
Nutshell
Custom Field (Person / Lead)
1:1Sierra Interactive Lead Tags categorize prospects (e.g., 'First-Time Buyer', 'Investor', 'Expired Listing'). Nutshell stores tags as comma-separated strings in a custom field (Lead_Tags__c) on both Person and Lead objects. Tags are not linked entities in Nutshell — search and filtering rely on text matching.
Sierra Interactive
Lead Source
Nutshell
Custom Field (Lead)
1:1Sierra Interactive Lead Source records where each contact originated (IDX website, referral, Zillow, etc.). Nutshell Lead has a standard 'source' field but it accepts only a single value. When Sierra records have multiple sources, we store the primary as Lead.Source and additional sources in Lead_Secondary_Sources__c.
Sierra Interactive
Note / Task
Nutshell
Note / Task
1:1Sierra Interactive notes and tasks attached to leads, companies, and deals migrate as Nutshell Notes and Tasks. Original timestamps, owners (resolved by email match to Nutshell users), and parent-record links are preserved. Nutshell Tasks support due date, priority, and status fields.
Sierra Interactive
Lead Pond
Nutshell
Custom Field (Lead)
1:1Sierra Interactive Lead Ponds organize leads into team queues (e.g., 'Hot Leads', 'Follow-Up Pool'). Nutshell does not have a native Pond equivalent. We map Pond membership to a custom pick-list field (Lead_Pond__c) on the Nutshell Lead record. Teams assign this field manually or via Nutshell automation after migration.
Sierra Interactive
Attachment / File
Nutshell
Attachment / File
1:1Sierra Interactive file attachments on leads, companies, and deals are downloaded and re-uploaded to Nutshell as file attachments on the corresponding Person, Company, or Deal record. Nutshell file size limits (25MB per file) apply. Inline images in rich-text notes are extracted and re-hosted as file attachments.
Sierra Interactive
User / Owner
Nutshell
User
1:1Sierra Interactive owner assignments resolve to Nutshell users by email match. Unmatched owners are flagged before migration — teams either invite them to Nutshell or reassign their records to a fallback owner. Nutshell's per-user pricing model means owner resolution also informs seat-count planning.

Pair-specific challenges
Migration approach
Audit Sierra Interactive data volume and custom field inventory
FlitStack AI connects to your Sierra Interactive REST API with scoped read credentials. We inventory all Lead, Company, Deal, Saved Listing, Action Plan, Note, and Task records; count unique custom fields; identify duplicate records and owner assignments; and generate a pre-migration volume report. This report drives the final quote and identifies any Nutshell pricing tier mismatch before the migration plan is committed.
Map Sierra Interactive objects and fields to Nutshell schema
We build a field-level mapping table for all standard and custom fields, create Nutshell custom fields for Saved_Listings__c, Lead_Tags__c, Lead_Pond__c, Action_Plan_Audit__c, and source_system_id__c on the appropriate objects, and resolve which Sierra Interactive leads route to Nutshell Person versus Lead. Owner resolution by email match is validated against your Nutshell user list. The mapping table is reviewed with your team before any data moves.
Create Nutshell custom fields and resolve company-person relationships
Nutshell requires Companies to exist before People can link via CompanyId. We sequence the migration: Companies first (preserving parent-company hierarchies), then People with CompanyId lookups resolved, then Leads, then Deals with Person and Company links. Custom fields are created in Nutshell before the bulk load begins so field IDs are available for the insert operation. This ordering ensures referential integrity across the entire dataset.
Run a test migration of 50–100 representative records
A representative slice of records spanning Leads, People, Companies, Deals, Notes, and Tasks migrates first. We generate a field-level diff showing the before/after value for each mapped field, verify saved listings serialization, confirm Action Plan audit data populated the custom field, and validate owner resolution. You review the test results and approve the full run or request mapping adjustments before proceeding.
Execute full migration with delta-pickup window
The full data set migrates into Nutshell via the JSON-RPC API. Your team continues working in Sierra Interactive throughout the run. A delta-pickup window (24–48 hours) captures any records created or modified during the cutover. We generate an audit log listing every inserted record, the source_system_id__c cross-reference, and any records that required manual override. One-click rollback is available if reconciliation reveals unexpected gaps.
Deliver Action Plan rebuild reference and post-migration support
After the migration completes, we deliver the Action_Plan_Audit__c JSON export and a step-by-step rebuild guide for your team to recreate Action Plan logic in Nutshell Tasks and automation sequences. We also provide a saved-listings reference sheet mapping each Person's Saved_Listings__c field to the original Sierra Interactive property records so your team can re-establish any active buyer-search contexts in Nutshell effectively.
