Overview
IDX Broker is primarily an IDX (Internet Data Exchange) platform that lets real estate agents display MLS listings on their websites and capture leads from property searches. It has a basic CRM module for contacts and leads, but its data model centers on listings, saved searches, and lead routing—not the full lifecycle and deal management that growing real estate teams need. HubSpot is a full CRM with contact lifecycle stages, deal pipelines, custom objects, and automation workflows. The migration from IDX Broker to HubSpot requires mapping IDX Broker contacts and leads to HubSpot contacts and companies, translating real estate property data into HubSpot's custom Properties object, and preserving owner assignments through email matching. FlitStack AI extracts data from IDX Broker via their REST API and CSV exports, cleans and deduplicates records, maps every field to HubSpot's property system (including any IDX Broker custom fields), and validates field-level before committing the full migration. Automations, saved search alerts, and MLS feed integrations do not transfer—those require manual rebuild in HubSpot's workflow builder and a new MLS widget integration.
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 IDX Broker 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.
IDX Broker
Contact (IDX Broker)
HubSpot
Contact (HubSpot)
1:1IDX Broker contacts map 1:1 to HubSpot contacts. Name, email, phone, and address fields translate directly. IDX Broker's contact create/update timestamps are preserved as HubSpot custom properties since HubSpot's native CreatedAt is set at migration time. Owner resolution happens via email match against HubSpot users.
IDX Broker
Lead (IDX Broker)
HubSpot
Contact (HubSpot)
many:1IDX Broker leads merge into HubSpot contacts. HubSpot has one contact object rather than separate contact and lead objects. The source lead status is preserved as a custom pick-list property in HubSpot, and lifecycle stage is set to 'lead' unless a more advanced stage was tracked in IDX Broker's extended fields.
IDX Broker
Company (IDX Broker)
HubSpot
Company (HubSpot)
1:1IDX Broker brokerages and real estate companies map to HubSpot companies. Company name, domain, industry, phone, and address fields translate directly. If IDX Broker stores agent teams as companies, those map to HubSpot teams or companies depending on your target schema.
IDX Broker
Property / Listing (IDX Broker)
HubSpot
Custom Property Object (HubSpot)
1:1IDX Broker property records (MLS listings with addresses, prices, MLS numbers, statuses, bedroom/bath counts) require a HubSpot custom object. FlitStack creates the Property object in HubSpot with custom fields for MLS number, listing price, status (Active/Pending/Sold), property type, square footage, and year built. Each property is associated to the relevant contact via a many-to-many relationship.
IDX Broker
Saved Search (IDX Broker)
HubSpot
HubSpot List
1:1IDX Broker saved searches are MLS-criteria-based alerts tied to the IDX website engine. HubSpot lists use contact-based criteria and cannot store MLS field logic. We preserve saved search criteria as a custom text property on the contact so your team can manually recreate matching lists in HubSpot.
IDX Broker
Agent / Owner (IDX Broker)
HubSpot
Owner (HubSpot)
1:1IDX Broker agents resolve to HubSpot owners by email match. If an IDX Broker agent record has no matching HubSpot user, the record is flagged for your team to either invite the agent to HubSpot or reassign to a fallback owner before migration commits.
IDX Broker
Showing Request (IDX Broker)
HubSpot
Task (HubSpot)
1:1IDX Broker showing requests map to HubSpot tasks assigned to the relevant agent/owner. Task subject, property reference, requested date, and contact association are preserved. Original request timestamps and owner assignments carry over. If a showing references a property, the task links to the HubSpot Property__c custom object and task status reflects IDX Broker status (Scheduled, Completed, Cancelled), allowing your team to track showings in HubSpot.
IDX Broker
Note (IDX Broker)
HubSpot
Engagement Note (HubSpot)
1:1IDX Broker notes on contacts, leads, and properties migrate to HubSpot engagement notes. Original timestamps, owners, and the parent record association (contact or property) are preserved. Notes attached to specific properties link to the corresponding custom Property object in HubSpot.
IDX Broker
Attachment / File (IDX Broker)
HubSpot
HubSpot Files
1:1IDX Broker file attachments (property images, documents, PDFs) are downloaded and re-uploaded to HubSpot Files. Files are linked to the parent contact or Property record in HubSpot. HubSpot's 25MB per-file limit applies; large media files over this threshold are flagged for selective upload.
IDX Broker
Custom Field (IDX Broker)
HubSpot
Custom Property (HubSpot)
1:1Any IDX Broker custom fields on contacts, leads, or properties translate to HubSpot custom properties. Field types map: text to single-line text, number to number, date to date/datetime, pick-list to pick-list. Enterprise-only IDX Broker custom objects translate to HubSpot custom objects following the same association rules as standard property objects.
IDX Broker
Lead Source (IDX Broker)
HubSpot
HubSpot Source Property
1:1IDX Broker lead source tracking (website form, MLS search, referral, etc.) maps to HubSpot's hs_analytics_source field on contacts. If your IDX Broker uses a custom lead source taxonomy, it migrates as a custom pick-list property and is mapped alongside the standard source.
IDX Broker
Tag / Label (IDX Broker)
HubSpot
HubSpot Tag
1:1IDX Broker tags on contacts and leads map to HubSpot tags. Tags are preserved as‑is; HubSpot’s tag model supports the same flat‑label structure that IDX Broker uses for contact classification. During migration, FlitStack AI imports tags exactly as they appear, preserving any hierarchical naming conventions you use. After migration, tags can be used in HubSpot workflows, lists, and reporting for segmentation and automation without any re‑tagging effort.

Migration approach
Scope and export IDX Broker data via API and CSV
FlitStack connects to your IDX Broker account via the REST API and exports all contacts, leads, companies, properties, saved searches, showing requests, and notes. For large datasets, we paginate across IDX Broker’s rate‑limited API windows and supplement with CSV exports where available, ensuring complete data retrieval even for high‑volume accounts. During extraction, we capture custom field definitions, tag taxonomies, and owner records to build a full field inventory before mapping begins. This step also identifies any missing critical fields (e.g., contacts without email) for data‑quality review.
Clean data and plan HubSpot schema
We deduplicate contacts, standardize address formats, and flag records with missing critical fields (no email, no name). For property records, we assess whether your team needs a HubSpot custom Properties object (Enterprise required) and, if so, deliver a schema plan specifying every custom field, pick-list value, and association before migration runs. Owner resolution maps IDX Broker agent IDs to HubSpot users by email match.
Build field-level mapping and create HubSpot custom properties
Every IDX Broker field maps to a HubSpot property (standard or custom). We create HubSpot custom properties for IDX Broker extended fields, property-specific data (MLS number, listing price, bedrooms), and audit fields (original create dates, source system IDs). For saved searches, we store the criteria as text on contacts. If a custom Properties object is needed, we provision it and its fields during this phase.
Run sample migration with field-level diff
A representative slice of 100–500 records migrates first—covering contacts, companies, properties, and a few showing requests. We generate a field‑level diff that displays the original IDX Broker value, the mapped HubSpot field, and the destination value for each record, allowing you to verify mapping accuracy and data integrity before the full run. You review the sample in HubSpot, confirm that lifecycle stages, custom property values, and owner assignments meet your expectations, and approve the mapping before FlitStack commits the complete migration.
Execute full migration with delta-pickup window
Full data migration runs against HubSpot, processing all contacts, companies, property records, showing requests, notes, and attachments in a single coordinated run. A delta‑pickup window (typically 24–48 hours) captures any new or modified records created in IDX Broker during cutover, ensuring HubSpot reflects the final state at go‑live. FlitStack maintains an audit log of every operation, and if reconciliation detects discrepancies, a one‑click rollback reverts the changes for correction. After validation against your source data, your team can start using HubSpot while IDX Broker is decommissioned.
