Overview
CRM and Deals for Zendesk organizes data around Leads, Contacts, Deals, and Organizations, with workflows and triggers handling automation. HubSpot CRM uses a similar but structurally different object model centered on Contacts, Companies, Deals, and a lifecycle_stage property that tracks where each contact sits in the buyer journey. The migration carries all Zendesk CRM records—leads, contacts, deals, organizations, custom objects, activities, and attachments—into HubSpot's object graph. The primary translation challenges are mapping Zendesk deal stages to HubSpot deal pipeline stages, translating Zendesk lead status values to HubSpot lifecycle stages, and handling any custom fields or custom objects Zendesk has in place. Zendesk workflows, triggers, and automations have no HubSpot equivalent at the data layer—those must be rebuilt using HubSpot's workflow builder post-migration. FlitStack sequences the migration using Zendesk's REST API for record extraction and HubSpot's bulk import API for data ingestion, with owner resolution by email match against HubSpot user accounts before records land.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a CRM and Deals for Zendesk 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.
CRM and Deals for Zendesk
Lead
HubSpot
Contact
1:1Zendesk Leads map directly to HubSpot Contacts. The migration routes every Zendesk lead record into HubSpot as a contact. HubSpot does not have a separate Lead object; all prospects land in the Contact object with lifecycle_stage reflecting their position in the funnel. The original Zendesk lead creation date is preserved as a custom datetime property for reporting continuity.
CRM and Deals for Zendesk
Contact
HubSpot
Contact
1:1Zendesk Contacts migrate to HubSpot Contacts 1:1. Standard fields (name, email, phone, job title, address) map to HubSpot's corresponding contact properties. Owner resolution happens by matching the Zendesk contact owner email to a HubSpot user email, with unmatched owners flagged before migration commits records to HubSpot.
CRM and Deals for Zendesk
Lead Status
HubSpot
Contact.lifecycle_stage
1:1Zendesk lead_status values (New, Open, Won, Lost) do not map directly to HubSpot lifecycle_stage because HubSpot's model uses a longer funnel progression. We map each Zendesk lead status value to the most appropriate HubSpot lifecycle_stage: 'New' and 'Open' typically map to 'lead' or 'MQL' based on your specification, 'Won' maps to 'customer', and 'Lost' maps to a custom property or lifecycle stage of your choosing.
CRM and Deals for Zendesk
Organization
HubSpot
Company
1:1Zendesk Organizations map to HubSpot Companies 1:1. Organization name maps to Company name, domain maps to the Company website property, industry maps to industry (with value-mapping for picklist alignment), and employee count maps to numberofemployees. Zendesk parent-child organization hierarchies are preserved using HubSpot's Parent Company field.
CRM and Deals for Zendesk
Contact-Organization Association
HubSpot
Contact-Company Association
1:1Zendesk allows a contact to be associated with multiple organizations. HubSpot contacts have one primary Company association plus secondary company associations via the Company Contacts feature. We migrate the most-recently-modified organization as the primary company (or the one you specify as primary) and surface all others as secondary company associations in HubSpot.
CRM and Deals for Zendesk
Deal
HubSpot
Deal
1:1Zendesk Deals map to HubSpot Deals. The deal name maps to dealname, amount maps to amount, close date maps to closedate, and owner maps to hubspot_owner_id resolved by email match. The primary translation work is mapping the Zendesk deal stage and status to the appropriate HubSpot deal pipeline and stage.
CRM and Deals for Zendesk
Deal Stage + Status
HubSpot
Deal.pipeline + Deal.stage
1:1Zendesk Deal status (open, won, lost) combined with deal stage name maps to HubSpot Deal stage values. If Zendesk has a single pipeline, we create one HubSpot deal pipeline. If Zendesk uses deal categories or multiple pipelines, we create corresponding HubSpot pipelines. Stage probability and forecast category are re-applied per HubSpot pipeline configuration.
CRM and Deals for Zendesk
Task / Call / Email / Meeting
HubSpot
Contact activity timeline
1:1Zendesk activities—calls, emails, meetings, and tasks—migrate to HubSpot's engagement timeline on the associated Contact record. HubSpot shows these as logged activities with original timestamps, activity type, and owner preserved. Emails map as email engagements, calls as call activities, meetings as meeting events, and tasks as notes on the contact timeline.
CRM and Deals for Zendesk
Note
HubSpot
Contact note
1:1Zendesk notes attached to contacts, deals, or organizations migrate to HubSpot as notes on the corresponding record. Rich-text formatting is preserved where possible. The note creation date and note author are mapped to HubSpot's note metadata.
CRM and Deals for Zendesk
Attachment / File
HubSpot
HubSpot file storage
1:1Files attached to Zendesk deals, contacts, or organizations are downloaded from Zendesk and re-uploaded to HubSpot's file storage, then linked to the target record. HubSpot allows up to 256MB per file on most plans, so files exceeding this limit are flagged for manual handling. Original filenames and creation dates are preserved on upload. Inline images embedded in notes are extracted and re-hosted individually in HubSpot's file manager to ensure they render correctly on the contact or deal timeline.
CRM and Deals for Zendesk
Custom Object
HubSpot
Custom Object or Custom Properties
1:1Zendesk custom objects (available on Suite Professional and Enterprise plans) map 1:1 to HubSpot custom objects. We create the corresponding HubSpot custom object schema, define its properties, and migrate all custom object records. Custom object associations that are many-to-many in Zendesk may require HubSpot custom junction objects, which we surface in the migration plan.
CRM and Deals for Zendesk
Zendesk User (Sales Rep)
HubSpot
HubSpot User
1:1Zendesk users who are assigned as deal owners or contact owners are resolved against HubSpot users by matching the email address. Unmatched users are flagged before migration runs so your team can either invite them to HubSpot or reassign their records to a designated fallback owner. No record lands without a valid HubSpot owner assignment.

Migration approach
Audit Zendesk data model and produce mapping specification
We connect to your Zendesk account via API and inventory all CRM objects: leads, contacts, organizations, deals, activities, custom objects, and custom fields. We cross-reference against your HubSpot portal to identify any properties that already exist and flag fields that need to be created. We produce a field-mapping specification and a pipeline-configuration worksheet that your HubSpot admin completes before the migration runs. This step also includes owner resolution planning—identifying which Zendesk users need HubSpot accounts created before data can be assigned.
Create HubSpot schema: pipelines, properties, and custom objects
Your HubSpot admin (or our team acting as admin) creates the deal pipelines and stages, custom contact and company properties, and any custom object schemas required by the mapping specification. This includes setting stage probability values, configuring the pipeline's closed-won and closed-lost stages, and enabling any HubSpot features (like secondary company associations) needed for the migration. We provide step-by-step instructions and validate that all required properties exist in HubSpot before data extraction begins.
Extract records from Zendesk via API with scoped read access
We use Zendesk's REST API to extract all CRM records: contacts, organizations, deals, activities, notes, and attachments. The extraction runs with scoped read-only access—your team continues working in Zendesk throughout this phase with no disruption to active records. We handle Zendesk API rate limits using backoff logic keyed to your account's quota headers. All extracted records are staged in a temporary environment, de-duplicated against any prior migration runs using source system IDs, and prepared for field-level transformation.
Run sample migration with field-level diff for validation
A representative slice of records—typically 100–500 covering a cross-section of object types, pipeline stages, and owner assignments—migrates into your HubSpot portal first. We generate a field-level diff showing the source value from Zendesk and the mapped value in HubSpot for every field. You review the diff to confirm that lead_status to lifecycle_stage mapping is correct, deal stages map to the right pipeline stages, and owner resolution worked for all reps. No full migration commits until you sign off on the sample validation.
Execute full migration with delta-pickup and audit log
The full record set migrates into HubSpot using HubSpot's bulk import API for maximum throughput. Owner resolution completes for all records—unresolved owners are assigned to a fallback owner and flagged for your review. A delta-pickup window of 24–48 hours captures any records created or modified in Zendesk during the cutover window so HubSpot reflects Zendesk's final state at go-live. FlitStack generates an audit log covering every record migrated, every field mapped, and every owner resolution decision. One-click rollback is available if post-migration reconciliation identifies data quality issues.
