Overview
Oracle Siebel stores contacts across two physical tables — S_CONTACT for person attributes and S_PARTY for party-role relationships — creating a denormalized structure that has no direct HubSpot equivalent. HubSpot uses a flat Contacts object with lifecycle stages, companies as separate lookup records, and deals tied to pipeline stages. The migration must decompose Siebel's party-role model, resolve position-based owner assignments to HubSpot user emails, and map Siebel opportunity stages to HubSpot pipeline stages value-by-value. We extract Siebel data through database-level reads (SIEBEL.S_CONTACT, SIEBEL.S_ORG_EXT, SIEBEL.S_OPTY, SIEBEL.S_DOC_QUOTE) or Siebel Migration export, transform records into HubSpot's property-based schema, and load via HubSpot's Contacts API and Companies API with bulk-record batching. Workflows, Siebel SmartScripts, and position hierarchies do not migrate — we export Siebel workflow definitions as a Word/Visio reference package for your HubSpot admin to rebuild in HubSpot workflows. Sample migration runs against a HubSpot sandbox before the full cutover commits. During the delta-pickup window, any changes made in Siebel after the initial extraction are captured and applied to HubSpot before final cutover. All migration steps are recorded in an audit log, and a one-click rollback option reverts the HubSpot environment to its pre-migration state if reconciliation detects discrepancies.

Object mapping
Each row shows how a Oracle Siebel 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.
Oracle Siebel
Account (S_ORG_EXT)
HubSpot
Company
1:1Siebel Account (S_ORG_EXT) maps to HubSpot Company. The Name, Website, Industry, and Address fields transfer directly. Parent Account linkage in S_ORG_EXT.PAR_ROW_ID maps to HubSpot's parent_company_id property. Multi-Organization (OU) segmentation requires a custom HubSpot Team or Company property for source-OU tagging.
Oracle Siebel
Contact (S_CONTACT + S_PARTY)
HubSpot
Contact
1:1Siebel Contact is split across two tables: S_CONTACT stores person attributes (name, email, phone, title) and S_PARTY stores the party-role record with ROW_ID linking. The migration JOINs these tables on S_CONTACT.PAR_ROW_ID = S_PARTY.ROW_ID to produce a flat HubSpot Contact record. Duplicate-check runs on email before insert.
Oracle Siebel
Opportunity (S_OPTY)
HubSpot
Deal
1:1Siebel Opportunity (S_OPTY) maps to HubSpot Deal. Pipeline name in S_OPTY.PROD_ID maps to HubSpot pipeline (created pre-migration). Stage names map value-by-value to HubSpot dealstage pick-list values. Probability percentages map to a custom property since HubSpot dealstage does not store probability natively.
Oracle Siebel
Quote (S_DOC_QUOTE)
HubSpot
Quote (Sales Hub Enterprise)
1:1Siebel Quote documents (S_DOC_QUOTE, S_QUOTE_ITEM) map to HubSpot Quotes only if the destination has Sales Hub Enterprise. Without that tier, quote line items migrate as custom properties on the associated Deal. Quote status (Draft, Submitted, Accepted, Revised) maps to a custom pick-list on the Deal.
Oracle Siebel
Service Request (S_SRV_REQ)
HubSpot
Ticket
1:1Siebel Service Requests (S_SRV_REQ) map to HubSpot Tickets. Area and Sub-Area fields map to Ticket status and a custom pick-list property. Severity maps to Ticket priority. The assigned Position resolves to a HubSpot user email. Open tickets migrate with original create dates preserved in custom datetime properties.
Oracle Siebel
Position (S_POSTN)
HubSpot
HubSpot Team / User
1:1Siebel Position (S_POSTN) is a job-role hierarchy, not a user account. The migration resolves Position assignments by finding the S_EMPLOYEE linked to S_POSTN, then matching S_EMPLOYEE.EMP_LOGIN to HubSpot user email. Unmatched Positions are flagged — your team creates HubSpot Teams or assigns records to a fallback owner before migration.
Oracle Siebel
Product (S_PROD_INT)
HubSpot
Product (HubSpot Product Library)
1:1Siebel Product (S_PROD_INT) where Type = 'Product' maps to HubSpot Product Library entries. Name, SKU, Unit Price, and Status transfer. Products used in Siebel Quotes map as line items on HubSpot Deals when Sales Hub Enterprise is present; otherwise they attach as Deal properties.
Oracle Siebel
Activity / Call / Email (S_EVT_ACT, S_DOC_ACT)
HubSpot
Engagement (email, call, meeting) / Note
1:1Siebel activities (S_EVT_ACT for calls/meetings, S_DOC_ACT for emails) map to HubSpot Engagements. Original timestamps, owners (resolved by Position-to-email), and parent record links (Contact or Opportunity) are preserved. Email body content migrates as a HubSpot email engagement record or as a Note if the body is rich-text.
Oracle Siebel
Account Extension (S_ORG_EXT_X)
HubSpot
Company Custom Properties
1:1Siebel custom extension columns on S_ORG_EXT (S_ORG_EXT_X table) migrate as HubSpot custom properties on the Company object. Property names are derived from Siebel column names with snake_case conversion. Pick-list values in Siebel extension columns require value-by-value mapping to HubSpot pick-list options.
Oracle Siebel
Contact Extension (S_CONTACT_X)
HubSpot
Contact Custom Properties
1:1Siebel custom extension columns on S_CONTACT (S_CONTACT_X table) migrate as HubSpot custom properties on the Contact object. The migration handles the S_PARTY join first so extension columns attach to the correct Contact record. Multi-value extension columns map as HubSpot multi-checkbox properties.
Oracle Siebel
Opportunity Extension (S_OPTY_X)
HubSpot
Deal Custom Properties
1:1Siebel custom extension columns on S_OPTY (S_OPTY_X table) migrate as HubSpot custom properties on the Deal object. Opportunity-level custom columns that tracked multi-currency amounts require currency-code tagging before mapping to HubSpot's single-currency Amount field. These custom properties are created in HubSpot prior to data load, with appropriate data types (text, number, picklist). Multi-select values are converted to multi-checkbox properties, ensuring fidelity of the original Siebel data.
Oracle Siebel
Literature / Attachment (S_LIT)
HubSpot
HubSpot File (via file_url)
1:1Siebel Literature records (S_LIT) with a FILE_REPO_URL pointing to Siebel's file repository re-upload to HubSpot Files. The migration extracts files from the Siebel file system path referenced in S_LIT.FILE_REPO_URL and attaches them to the parent Contact, Company, or Deal record in HubSpot.
Oracle Siebel
Order (S_ORDER)
HubSpot
Deal Custom Property / Associated Record
1:1Siebel Orders (S_ORDER) have no direct HubSpot equivalent. Closed Won deals that generated orders can carry a custom 'Siebel Order Number' property migrated from S_ORDER.ORDER_NUM. Order line items (S_ORDER_ITEM) migrate as a custom JSON property or as line-item notes on the associated Deal.

Pair-specific challenges
Migration approach
Inventory Siebel schema and extract sample records
FlitStack AI connects to your Siebel database (read-only access to SIEBEL schema) or uses Siebel Migration export to catalog the full object inventory. We identify S_CONTACT and S_PARTY join requirements, custom extension tables (S_*_X), Organization (OU) count, Position hierarchy depth, and Opportunity pipeline definitions. A schema summary document is delivered within 48 hours of access provisioning, listing every table that will migrate and the row counts per object.
Map Positions to HubSpot users and create Teams for OUs
We extract the Position-to-Employee mapping from S_POSTN and S_EMPLOYEE. Each unique employee login is matched against your planned HubSpot user list by email. Unmatched employees are flagged with a recommendation: invite them to HubSpot, assign them to a fallback owner, or collapse their records under a team lead. Siebel Organizations map to HubSpot Teams — your HubSpot admin creates the Teams before data lands.
Run sample migration against HubSpot sandbox with field-level diff
A representative slice of records (typically 200–500 across Contacts, Companies, Deals, and Tickets) migrates to a HubSpot sandbox or test account. We generate a field-level diff showing the exact value in Siebel versus the resulting value in HubSpot for every mapped field. You review the diff to confirm lifecycle stage mapping logic, Position-to-owner resolution, and Quote handling for your HubSpot plan tier. No data commits to production until you sign off on the sample diff.
Execute full migration with delta-pickup window
Full data migration runs against HubSpot production. Companies load first (no dependencies), then Contacts/Leads with S_CONTACT/S_PARTY JOIN resolution, then Deals with pipeline and stage mapping, then Tickets. A delta-pickup window (24–48 hours after initial load) captures any records created or modified in Siebel during the cutover. All operations are logged to an audit trail. One-click rollback reverts to the pre-migration state if reconciliation fails.
Deliver Siebel workflow export for HubSpot rebuild
We export Siebel workflow definitions (Business Processes, Workflow Policies, SmartScripts) as XML and PDF reference documents. These are organized by object and trigger condition so your HubSpot admin can match each Siebel automation to a HubSpot workflow equivalent. This export does not include the automations themselves — it is a rebuild specification. FlitStack does not rebuild automations; that is a separate services engagement.
