Overview
Kylas Sales CRM organizes sales data around leads, contacts, deals, and companies with customizable pipeline stages and built-in workflow automation. HubSpot structures the same entities using contacts with lifecycle stages, companies, and deals with pipeline-stage mapping. The migration carries over all standard objects — leads route to HubSpot contacts with lifecycle_stage applied, companies map directly, deals map to HubSpot deals with pipeline stages value-mapped, and activity history (calls, emails, meetings, notes) migrates with original timestamps and owner assignments. Custom fields from Kylas become HubSpot custom properties, though pick-list values require value-by-value mapping. Kylas workflow automations, including lead routing rules and stage-triggered actions, do not migrate and must be rebuilt in HubSpot's automation tools. FlitStack sequences the migration so foreign-key relationships (contact-company, deal-contact) resolve correctly and runs a sample migration with field-level diff before committing the full dataset.
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 Kylas Sales CRM 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.
Kylas Sales CRM
Lead
HubSpot
Contact
1:1Kylas leads map to HubSpot contacts. The lead's status and source information migrate as HubSpot contact properties. Kylas lead scoring values transfer to HubSpot's custom numeric property. The migration assigns the appropriate HubSpot lifecycle stage based on Kylas lead status or your specified routing rule.
Kylas Sales CRM
Contact
HubSpot
Contact
1:1Kylas contacts map 1:1 to HubSpot contacts. All standard properties (name, email, phone, address, job title) map directly. Owner assignment resolves by email match against HubSpot users. Multi-phone fields map to HubSpot's phone and mobilephone properties. Original create dates preserve in a custom datetime property.
Kylas Sales CRM
Company
HubSpot
Company
1:1Kylas company records map to HubSpot companies. Company name, domain, industry, employee count, and annual revenue map to HubSpot's equivalent properties. Kylas parent-child company hierarchies preserve via HubSpot's parent company association. Custom company properties migrate as HubSpot custom properties.
Kylas Sales CRM
Deal
HubSpot
Deal
1:1Kylas deals map to HubSpot deals. The deal name, amount, expected close date, and owner assign directly. Kylas pipeline and stage names map to HubSpot deal pipelines and stage values — each Kylas pipeline becomes a HubSpot deal pipeline, and Kylas stage names map value-by-value to HubSpot stage names within that pipeline.
Kylas Sales CRM
Pipeline
HubSpot
Deal Pipeline
1:1Kylas's multiple named pipelines map to HubSpot deal pipelines. Each Kylas pipeline creates a corresponding HubSpot pipeline. Stage names translate value-by-value — Kylas stage labels map to HubSpot stage names, and stage order and probability percentages map if Kylas stores them. Custom pipeline properties in Kylas become HubSpot deal custom properties.
Kylas Sales CRM
Activity (Call)
HubSpot
Calls
1:1Kylas call logs migrate to HubSpot calls with original timestamp, duration, direction (inbound/outbound), and outcome preserved. Call notes map to HubSpot call body. The call associates to the matching HubSpot contact or company record by email or company domain lookup.
Kylas Sales CRM
Activity (Email)
HubSpot
Emails
1:1Kylas email history migrates to HubSpot emails with subject, body, timestamp, and direction preserved. Emails attach to the corresponding HubSpot contact or company record. Kylas email templates do not migrate — they must be recreated in HubSpot's email template library.
Kylas Sales CRM
Activity (Meeting)
HubSpot
Meetings
1:1Kylas meeting records migrate to HubSpot meetings with meeting title, start/end times, attendees, location, and outcome preserved. The meeting links to the associated HubSpot contact or deal. Kylas meeting templates do not migrate and require recreation in HubSpot's meeting scheduler.
Kylas Sales CRM
Note
HubSpot
Notes
1:1Kylas notes map to HubSpot notes with content, create date, and owner preserved. Notes attach to the correct HubSpot record (contact, company, or deal) based on the original Kylas association. Rich-text formatting in Kylas notes translates to HubSpot's note body format.
Kylas Sales CRM
Custom Field (Contact)
HubSpot
Custom Property (Contact)
1:1Kylas custom contact fields migrate as HubSpot custom properties. Pick-list custom fields require value-by-value mapping since HubSpot manages option labels independently. Numeric and date custom fields map directly. Boolean fields map to HubSpot's checkbox property type.
Kylas Sales CRM
Custom Field (Deal)
HubSpot
Custom Property (Deal)
1:1Kylas custom deal properties migrate to HubSpot deal custom properties. Currency-formatted fields map to HubSpot's number or currency property type. Multi-select pick-list values require manual value-mapping during migration planning. Stage-linked custom fields map based on the deal's final stage value.
Kylas Sales CRM
Task / Reminder
HubSpot
Tasks
1:1Kylas tasks and reminders migrate to HubSpot tasks with subject, due date, status, priority, and owner preserved. Completed vs. open status maps to HubSpot task completion. Kylas task recurrence rules do not carry over — recurring task logic must be rebuilt in HubSpot's workflow automation.
Kylas Sales CRM
Product / Line Item
HubSpot
Product
1:1Kylas products associated with deals map to HubSpot products. Product name, SKU, price, and description migrate directly. Kylas line items on deals translate to HubSpot line items associated with the migrated deal record.
Kylas Sales CRM
Lead Scoring Data
HubSpot
Custom Numeric Property
1:1Kylas lead scores migrate as a custom numeric property on HubSpot contacts. HubSpot's native lead scoring (available on Professional+ tiers) uses different criteria weights — your team decides whether to adopt HubSpot's native scoring model or continue using the migrated Kylas score values for comparison.

Migration approach
Audit Kylas data volume and schema before mapping
FlitStack starts by querying Kylas's API to enumerate all active objects: leads, contacts, companies, deals, activities, and custom fields. We capture record counts per object, field types and pick-list values, pipeline and stage configurations, and owner assignments. This audit identifies which objects require custom field creation in HubSpot, which pick-lists need value-mapping, and how many HubSpot pipelines need pre-configuration before data can land.
Map Kylas pipelines to HubSpot deal pipelines
Each Kylas pipeline becomes a HubSpot deal pipeline. FlitStack generates a pipeline mapping document listing every Kylas pipeline name, its stages, and the proposed HubSpot pipeline name and stage labels. Your HubSpot admin creates the pipelines and stages in HubSpot before the migration run. Stage-probability percentages map per stage so deal forecasting continuity is preserved. We validate the pipeline configuration against your Kylas stage names before proceeding to field mapping.
Resolve owners by email match against HubSpot users
Kylas stores owner assignments by user ID. FlitStack resolves each Kylas owner to a HubSpot user by matching email addresses. Any Kylas owner whose email does not match an existing HubSpot user is flagged in a pre-migration report. Your team either invites those users to HubSpot before migration or assigns their records to a fallback owner. No record migrates without a resolved HubSpot owner — unowned records would appear as unassigned in HubSpot's deal and contact views.
Run a sample migration with field-level diff
A representative slice of 200–500 records migrates first, spanning contacts, companies, deals, and activity history. FlitStack generates a field-level diff comparing Kylas source values against the resulting HubSpot records. You verify that lifecycle stage mapping is correct, pipeline-to-stage mapping resolved as expected, owner resolution is complete, and activity associations link to the right contact or company. Sample migration approval gates the full run.
Execute full migration with delta-pickup window
The full dataset migrates to HubSpot — companies first (HubSpot requires company existence before contact association), then contacts and leads, then deals linked to contacts, then activities. A delta-pickup window of 24–48 hours captures any records modified in Kylas during the cutover period. FlitStack's audit log records every operation. If reconciliation reveals missing or mis-mapped records, one-click rollback reverts the HubSpot dataset so your team can investigate and re-run the migration.
