Overview
Migrating from Oracle Siebel to GoHighLevel is a platform-type migration: Siebel is an enterprise CRM with a deep party-based schema (S_PARTY as root for both Organizations and Contacts), mature quote-to-order workflows, and per-user licensing at $3,750. GoHighLevel is a SaaS all-in-one for agencies and SMBs with CRM, pipelines, and marketing automation at $97 per month. The structural gap is wide—Siebel's regulated-industry data models and quote-to-cash workflows have no direct GoHighLevel equivalent. We extract Siebel's S_ORG_EXT Accounts, S_CONTACT Contacts, S_OPTY Opportunities, S_SRV_REQ Cases, and Activity records via Siebel Migration or REST API, then map them into GoHighLevel's Contact, Company, and Opportunity objects. Siebel's custom extension tables require manual recreation in GoHighLevel's custom fields UI before data import. We do not migrate Siebel Workflow Processes, Siebel EAI integrations, or the Siebel File System literature binary files—those require a separate rebuild and re-upload plan.
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 Oracle Siebel object lands in HighLevel, 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)
HighLevel
Company
1:1Siebel Accounts map to S_ORG_EXT with S_PARTY as the parent row. GoHighLevel's Company object holds the Organization name, address, phone, and website. We extract S_ORG_EXT and its S_PARTY parent row in a single pass, then insert into GoHighLevel Company. The S_ORG_EXT PARTY_U1 (unique identifier) is preserved in a GoHighLevel custom field siebel_party_id__c for audit traceability.
Oracle Siebel
Contact (S_CONTACT)
HighLevel
Contact
1:1Siebel Contacts map to S_CONTACT with S_PARTY as the parent. GoHighLevel Contact holds name, email, phone, and address. We resolve the parent S_PARTY row before Contact insert to satisfy GoHighLevel's Company lookup (the Contact's primaryCompany field). Any Siebel Position assignment (responsibility relationship) maps to a GoHighLevel custom field siebel_position__c; the organizational hierarchy does not translate into GoHighLevel's flat user model.
Oracle Siebel
Opportunity (S_OPTY)
HighLevel
Opportunity
1:1Siebel Opportunities map to S_OPTY with pipeline stage, revenue amounts, and close dates. GoHighLevel Opportunities track deals through a customizable pipeline with stages we create during setup. The Siebel pipeline stage (OPTY_STAGE) maps to a GoHighLevel Pipeline Stage; stage probability migrates to the GoHighLevel stage percentage field. Opportunity-Account linking resolves to GoHighLevel Opportunity-Company relationship.
Oracle Siebel
Quote (S_DOC_QUOTE)
HighLevel
Custom Object or Deal Note
many:1Siebel Quote (S_DOC_QUOTE and S_QUOTE_ITEM) has no GoHighLevel native equivalent. GoHighLevel Opportunities track deal values but do not generate line-item documents. For migrations where Quote records carry critical business data (pricing terms, approval history), we map Quote header and line items to a GoHighLevel Custom Object with a Lookup to the matching Opportunity. The customer manually rebuilds Quote templates in GoHighLevel's document or workflow layer.
Oracle Siebel
Order (S_ORDER)
HighLevel
Not Migrated (Archived)
lossySiebel Order records (S_ORDER, S_ORDER_ITEM) represent closed-won deals with fulfillment data. GoHighLevel has no Order object. We extract Order headers and line items as a structured CSV export and deliver them as an Order History archive for compliance retention. The customer uploads this to a document store or ERP. Live Order management does not continue in GoHighLevel.
Oracle Siebel
Case (S_SRV_REQ)
HighLevel
Custom Object or Ticket
1:1Siebel Service Requests map to S_SRV_REQ with status, priority, assigned Position, and related Activity logs. GoHighLevel does not have a native Case object at base tier. We map S_SRV_REQ to a GoHighLevel Custom Object (e.g., Cases) with status, priority, and description fields, plus a Workflow for assignment routing. If the customer uses GoHighLevel's messaging-centric support features, cases can alternatively map to the Conversations inbox with a tagged custom field.
Oracle Siebel
Activity (S_EVT_ACT)
HighLevel
Task
1:1Siebel Activities (calls, meetings, tasks, emails) map to GoHighLevel Tasks. We extract the activity type, date, owner, and description. GoHighLevel Tasks display in the Contact and Opportunity timeline. Siebel's activity type codes (CALL, MTG, TASK, EMAIL) map to GoHighLevel Task type values. Parent Contact or Account resolution uses the Siebel foreign-key row IDs matched to the migrated S_PARTY records.
Oracle Siebel
Custom Extension Table
HighLevel
Custom Field (Contact or Opportunity)
lossySiebel custom fields built via Siebel Tools (extension tables or columns on S_CONTACT, S_ORG_EXT, S_OPTY) require manual recreation in GoHighLevel before data import. We audit the extension table schema during discovery, document the data type mapping (VARCHAR to String, NUMBER to Number, DATETIME to Date/DateTime), and deliver a GoHighLevel custom field creation checklist. GoHighLevel differentiates Contact custom fields (per-person attributes) from Opportunity custom fields (per-deal attributes)—the Siebel field's parent table determines which GoHighLevel object receives the field. Migration waits for custom field creation before importing extension data.

Oracle Siebel gotchas
Version gating for Siebel Cloud Manager OCI migration
S_PARTY base table requires parent-first migration sequencing
REST API 30 req/min rate limit throttles bulk extraction
Siebel Tools SRF compilation required after extension table changes
Literature files require separate file system export
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Discovery and Siebel version audit
We audit the source Siebel environment for version (pre-18.12 vs 18.12+), deployment model (on-prem vs OCI), custom extension table inventory, quote and order record volume, case history, and activity count. We identify which Siebel Migration tool is available (Siebel Migration package file for 18.11+, Siebel Cloud Manager for OCI, or REST API with the 30 req/min rate limit). We also confirm whether the destination GoHighLevel account exists, which tier is licensed, and whether the white-label or agency structure is in use. The discovery output is a written migration scope with record counts per object and a GoHighLevel custom field creation checklist.
GoHighLevel schema preparation
We work with the customer's GoHighLevel admin to pre-create all required custom fields based on the Siebel extension table audit. Contact custom fields and Opportunity custom fields are created separately per GoHighLevel's object model. Pipeline stages are defined to match the Siebel Opportunity stages (or redesigned if the customer prefers a simplified pipeline). If the customer requires Case migration, we create a Cases Custom Object with status, priority, and description fields. Schema must be validated before extraction begins; GoHighLevel's UI-only field creation is a manual step the customer controls.
S_PARTY-first extraction sequencing
We extract Siebel data in dependency order: first S_PARTY rows with their ROW_IDs and basic party attributes, then S_ORG_EXT (Organizations) with the S_PARTY ROW_ID injected as a foreign key, then S_CONTACT (Contacts) with S_PARTY ROW_ID and Organization lookup. Following the party tables, we extract S_OPTY (Opportunities), S_DOC_QUOTE (Quotes, archived), S_ORDER (Orders, archived), S_SRV_REQ (Cases), and S_EVT_ACT (Activities). Siebel Migration package files export all selected resources atomically; REST API extraction requires per-object pagination and a post-extraction join pass to inject S_PARTY ROW_IDs into child records.
GoHighLevel import in object dependency order
We import into GoHighLevel in strict order: Companies first (from S_ORG_EXT), then Contacts with Company lookup resolved (from S_CONTACT), then Opportunities with Company lookup resolved (from S_OPTY). Custom Objects for Cases and archived Quotes follow. Tasks and Activity records land last with Contact and Company lookups resolved via the siebel_party_id__c audit field. Each phase emits a row-count reconciliation report. Bulk import uses GoHighLevel's Contacts API for Contact and Company records, with batch chunking to stay within any undocumented rate limits.
Literature and file archive delivery
We extract S_LIT metadata and the associated file paths from the Siebel File System. Binary files are packaged and delivered as a named zip archive for the customer's admin to re-upload to GoHighLevel or a linked file store. Literature metadata (document name, type, description) is included as a CSV alongside the binary archive for re-upload reference. This step is decoupled from the live CRM import and can be completed post-migration.
Cutover, validation, and post-migration handoff
We freeze Siebel writes during the cutover window, run a final delta migration of any records modified during the migration, then mark GoHighLevel as the system of record. We deliver a GoHighLevel custom field completion checklist (for any fields not yet created), a Workflow rebuild inventory (documenting Siebel Workflow Processes for the customer's admin to rebuild in GoHighLevel's workflow builder), and a Literature file upload guide. We support a three-day hypercare window for reconciliation issues. We do not rebuild Siebel Workflow Processes, Siebel EAI integrations, or Siebel Sequences in GoHighLevel as part of standard migration scope.
