Overview
Property Shell targets property developers and project marketers with a vertically oriented CRM that combines lead capture, interactive mapping, and contract management in one portal. HubSpot offers a horizontally scalable all-in-one platform spanning marketing, sales, service, and operations with native AI (HubSpot Breeze), an extensive integration marketplace, and tiered pricing that grows with team size. The migration carries Property Shell's standard CRM objects — contacts, companies, deals, and pipeline data — into HubSpot's contact, company, deal, and ticket objects. Property Shell's contract-centric fields (variations, upgrades, settlement data) and its interactive mapping associations have no native HubSpot equivalent; FlitStack creates HubSpot custom properties and custom objects to preserve that context. Marketing automations, lead nurture sequences, and any custom property-development workflows must be rebuilt in HubSpot Workflows or Operations Hub — FlitStack exports your automation definitions as a rebuild reference. The migration runs via scoped read-only API access to Property Shell, so your team continues working in the source system throughout. A delta-pickup window captures records modified during cutover before the HubSpot portal goes live.
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 Property Shell object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Property Shell
Contact
HubSpot
Contact
1:1Property Shell contacts map directly to HubSpot contacts. All standard fields (name, email, phone, address) transfer 1:1. Owner is resolved by email match against HubSpot users. Contacts without a primary company link to a designated default HubSpot company record.
Property Shell
Lead
HubSpot
Lead
1:1Property Shell leads route to HubSpot leads. Lead score from Property Shell's AI lead scoring becomes a HubSpot custom number property (Lead_Score__c). Lead status pick-list values are mapped value-by-value to HubSpot's lead status field.
Property Shell
Company
HubSpot
Company
1:1Property Shell companies map to HubSpot companies. Company hierarchies (parent and child companies) are preserved via HubSpot's parent company association. Multi-contact companies maintain all associated contact records under the single company.
Property Shell
Deal
HubSpot
Deal
1:1Property Shell deals map to HubSpot deals. The deal name, amount, close date, and owner transfer directly. Each Property Shell pipeline maps to a HubSpot pipeline. Deal stage values are mapped value-by-value to the corresponding HubSpot pipeline stage.
Property Shell
Pipeline
HubSpot
Pipeline
1:1Each Property Shell pipeline becomes a HubSpot pipeline. Stage names, probabilities, and forecast categories transfer as the HubSpot pipeline stage configuration. Stage-entered timestamps are preserved as HubSpot custom datetime properties for reporting continuity.
Property Shell
Contract
HubSpot
Custom Object: Contract
1:1Property Shell's contract management records have no native HubSpot equivalent. FlitStack creates a HubSpot Contract custom object with fields for contract value, variation total, upgrade flags, and settlement date. Contracts are associated to the originating HubSpot deal via a custom lookup relationship.
Property Shell
Interactive Map Association
HubSpot
Custom Object: Property Unit
1:1Property Shell's interactive map lot/unit associations — stage, release, sales status, size, price — become a HubSpot Property Unit custom object linked to the HubSpot company or deal. This preserves display-suite data that would otherwise be lost in a generic deal migration.
Property Shell
Custom Property (per-object)
HubSpot
Custom Property
1:1Every Property Shell custom property — whether on contact, company, deal, or contract — is evaluated against HubSpot's standard field catalogue. Matching standard fields are used; non-matching properties are created as HubSpot custom properties with the original data type preserved (text, number, date, picklist, checkbox).
Property Shell
Attachment / File
HubSpot
HubSpot Files
1:1Property Shell file attachments on contacts, companies, or deals are downloaded and re-uploaded to HubSpot Files. File size limits apply (HubSpot supports up to 250 MB per file in most plans). Inline images in notes are extracted and rehosted within HubSpot's file CDN.
Property Shell
Owner / User
HubSpot
User
1:1Property Shell owner records are resolved against HubSpot users by email address match. Unmatched owners are flagged in the migration report with their Property Shell record count so your team can either invite them to HubSpot or reassign records to a fallback owner before the migration runs.

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.
Property Shell gotchas
No documented public API for data export
Highly customised per-customer schema requires pre-migration field audit
Interactive Maps are visualisation-layer only and cannot be migrated
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Extract Property Shell data via scoped API access
FlitStack connects to Property Shell using read-only API credentials scoped to the CRM objects required for migration. We export contacts, companies, deals, pipelines, contract records, and any custom properties in scope. The extraction runs against a representative data slice first (typically 200–500 records) to validate field completeness and identify any non-standard data — such as free-text stage values that need cleansing before a full value-mapping plan can be built.
Build the HubSpot schema plan and custom object definitions
Before data moves, FlitStack delivers a HubSpot schema setup plan covering: standard object field mapping (contacts, companies, deals), custom property creation for Property Shell fields that have no HubSpot standard equivalent, and the Contract and Property Unit custom object definitions with field names, types, and pick-list values. Your HubSpot admin creates these objects in the destination portal before the migration load. We recommend completing this step 3–5 business days before the migration run.
Resolve owners and validate data quality
FlitStack runs the owner-resolution step — matching Property Shell owner email addresses to HubSpot user records. An owner-resolution report is delivered listing matched users, unmatched owners, and the number of records affected per unmatched owner. Your team acts on this report by either inviting the owner to HubSpot or designating a fallback owner. Concurrently, data quality checks identify duplicate contacts (matched by email), missing required fields, and records with free-text values that should be pick-list fields. These are resolved or flagged before the migration load.
Run sample migration with field-level diff
A representative slice — contacts, companies, deals, contracts, and a sample of custom property records — migrates into the live HubSpot portal. FlitStack generates a field-level diff report comparing source values against destination values for every mapped field. Your team reviews the diff to verify that lifecycle stage values, deal amounts, pipeline stage assignments, and custom property data landed correctly. Any discrepancies are corrected in the mapping configuration before the full migration commits.
Execute full migration with delta-pickup cutover
The full data migration runs against HubSpot. A delta-pickup window of 24–48 hours is opened from the moment the migration begins, capturing any new or modified records created in Property Shell during the cutover. FlitStack's audit log records every operation — record count loaded, skipped, and failed — and one-click rollback is available if reconciliation identifies unexpected data divergence. After rollback window closes, the HubSpot portal is confirmed as the live system of record.
