Overview
Sercom typically stores customer and operational data across contact records, company profiles, deal or project entries, and support tickets. HubSpot models this data as Contacts, Companies, Deals (with pipeline stages), and Tickets (with pipeline stages). The migration translates Sercom's contact fields into HubSpot's Contact properties — mapping standard fields like email, phone, and job title directly, and routing any Sercom-specific custom fields to HubSpot custom properties that your admin pre-creates. Company data maps to HubSpot's Companies, preserving domain, industry, and employee count where present. Deals migrate as HubSpot Deals with pipeline and stage values translated per your destination pipeline configuration. Tickets migrate as HubSpot Tickets with subject, content, and priority mapped to custom properties where the destination field names differ. We run a sample migration with field-level diff before the full load, and a 24–48h delta window captures records modified during cutover. Workflows, automations, and notification templates do not migrate — we export those definitions as a rebuild reference for your HubSpot admin.

Object mapping
Each row shows how a Sercom 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.
Sercom
Contact
HubSpot
Contact
1:1Sercom contact records migrate directly to HubSpot Contacts. All standard fields (name, email, phone, job title) map 1:1. Contacts associated with multiple Sercom companies get their primary company assigned as the HubSpot primary company; secondary associations are preserved via HubSpot's Company Contact Associations feature.
Sercom
Custom Contact Field
HubSpot
Custom Property (Contact)
1:1Sercom custom fields on contact records that do not match HubSpot's standard property names require pre-creation in HubSpot Settings > Properties before migration. FlitStack delivers a custom property manifest listing each Sercom field name, its data type, and the HubSpot property internal name your admin should create.
Sercom
Company
HubSpot
Company
1:1Sercom company records map to HubSpot Companies. The company name maps to the HubSpot name property, domain maps to the website property, and industry maps to HubSpot's industry pick-list with value mapping applied for any Sercom industry values not in HubSpot's default list.
Sercom
Custom Company Field
HubSpot
Custom Property (Company)
1:1Sercom custom fields on company records are migrated as HubSpot custom properties on the Company object. Each property must be pre-created in HubSpot Settings with the matching field type — dropdown, number, date, text, or checkbox — and pick-list options defined as needed. FlitStack provides a manifest listing each Sercom field name, its data type, and the suggested HubSpot internal name your admin creates, ensuring data loads without skipping fields.
Sercom
Deal / Project Record
HubSpot
Deal
1:1Sercom deal or project records migrate as HubSpot Deals. The deal name, amount, and close date map directly. Sercom's internal stage or status field maps to a HubSpot pipeline stage via value mapping — if Sercom uses multiple stage values across record types, we map each to a distinct HubSpot pipeline stage for your pre-configured destination pipeline.
Sercom
Deal Stage / Status
HubSpot
Deal Pipeline Stage
1:1Sercom stage or status pick-list values are mapped to HubSpot pipeline stage names. The mapping is 1:1 per pipeline. Stage probability values are not preserved in HubSpot's stage definitions but can be configured as custom probability fields on the Deal object.
Sercom
Support Case / Ticket
HubSpot
Ticket
1:1Sercom support cases migrate as HubSpot Tickets. The case subject maps to the ticket subject, and case content or description maps to the ticket content property. Priority flags map to a custom ticket property (Ticket_Priority__c) since HubSpot Tickets have no built-in priority field.
Sercom
Ticket Status
HubSpot
Ticket Pipeline Stage
1:1Sercom ticket status values (open, in progress, resolved, closed) map to HubSpot Ticket pipeline stage names. If Sercom uses additional statuses beyond HubSpot's default set, those are mapped via value mapping and your admin configures the destination pipeline stages accordingly.
Sercom
Activity (Call, Email, Meeting)
HubSpot
Engagement (Call, Email, Meeting)
1:1Sercom engagement records map to HubSpot Engagements. Calls map to HubSpot calls with subject, duration, outcome, and recording URL preserved. Emails map as engagement emails with body content and timestamp. Meetings map with subject, start/end times, and the associated contact or deal link.
Sercom
Note
HubSpot
Note
1:1Sercom notes migrate to HubSpot Notes attached to the corresponding Contact, Company, or Deal record. The note body maps to HubSpot's note body property. If Sercom stores notes with create and update timestamps, those are preserved as HubSpot note metadata.
Sercom
Product / Service Item
HubSpot
Product
1:1Sercom product or service line records map to HubSpot Products. Product name, description, price, and SKU map to the corresponding HubSpot Product properties. Products must exist before line items can attach to Deals in HubSpot, so we sequence the migration to load Products before Deals.
Sercom
Line Item
HubSpot
Line Item
1:1Sercom line item records attached to deals map to HubSpot Line Items with quantity, price, and product reference. The line item is linked to the migrated Deal via the dealId field. Each line item's product reference is resolved against the migrated Product records.
Sercom
Attachment / File
HubSpot
File
1:1Sercom file attachments on contacts, companies, deals, or tickets are downloaded and re-uploaded to HubSpot Files. Each file is associated with the target record by ID after upload. HubSpot's file size limit is 250 MB per file; larger files are flagged for manual handling.
Sercom
Owner / User
HubSpot
Owner
1:1Sercom owner IDs are resolved by email address match against HubSpot Users. The owner email on each Sercom record is matched to a HubSpot user account; if no match is found, the record is assigned to a designated fallback HubSpot user and flagged in the migration report for admin review.

Migration approach
Audit Sercom data model and extract field inventory
FlitStack connects to Sercom via scoped read-access API and inventories all contact, company, deal, ticket, activity, and attachment records. We generate a field inventory listing every Sercom field name, data type, and record count. This inventory drives the custom property manifest — your HubSpot admin creates any missing HubSpot custom properties before the migration run. We also identify any Sercom records with duplicate email addresses, missing owners, or orphaned foreign keys that require resolution before import.
Build field mapping and value mapping specifications
We build a field mapping specification that maps every Sercom field to its HubSpot destination property. Standard fields map 1:1 (firstname to firstname, email to email). Custom Sercom fields are flagged for custom property creation. Pick-list fields like deal stage and ticket status get a value mapping table translating each Sercom value to its HubSpot pipeline stage name. The mapping spec is delivered as a spreadsheet and reviewed with your team before any test migration runs.
Create HubSpot custom properties and configure pipelines
Your HubSpot admin creates the custom properties identified in the field inventory. We recommend setting up the destination Deal pipeline and Ticket pipeline in HubSpot before migration — configuring stage names that match your Sercom stage values. Products should be loaded before Deals since Line Items reference Products. If you use multiple deal pipelines in HubSpot, tell us which Sercom records should route to which pipeline so we can apply the correct pipeline ID at import time.
Run sample migration with field-level diff
A representative slice of Sercom records — typically 100–500 across contacts, companies, deals, tickets, and a sample of activities — migrates to your HubSpot staging environment first. We generate a field-level diff comparing source values against destination values for every mapped field. You review the diff to verify stage mapping, owner resolution, and custom field population. Any mismatches are corrected in the mapping spec before the full migration runs.
Execute full migration with delta-pickup window
The full Sercom dataset migrates to HubSpot in sequenced batches: Products first (for Line Item references), then Companies, then Contacts, then Deals, then Tickets, then Activities, then Files. A delta-pickup window of 24–48 hours captures any records modified in Sercom during the cutover. All operations are logged in an audit trail. If reconciliation reveals data gaps, one-click rollback reverts the HubSpot load and the migration re-runs with corrections.
