Overview
Apollo ERP operates as a sales intelligence and engagement platform with a Contact model, an Account model, a Deal model, Tasks, and Sequences as core objects. Its enrichment data — employment history, intent signals, and buying triggers — is Apollo-proprietary and has no native equivalent in HighLevel's schema. HighLevel models Contacts, Companies, Opportunities, and Tasks natively, with a separate Workflows engine for automation that is architecturally unrelated to Apollo's Sequences. FlitStack AI migrates all exportable contact records, company records, deal/opportunity records, and tasks from Apollo into their HighLevel equivalents, flags enrichment-only fields for manual re-enrichment or re-discovery, and maps every custom field by type. We sequence the migration to resolve foreign keys correctly (accounts before contacts before opportunities), run a sample migration with a field-level diff before committing the full dataset, and capture any records modified during the cutover window via a delta pickup. Workflows and Sequences do not migrate — they require a rebuild in HighLevel's Workflows builder, and we provide the export reference to support that effort.
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 Apollo ERP 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.
Apollo ERP
Contact
HighLevel
Contact
1:1Apollo contacts map directly to HighLevel contacts. The email address is the primary key for de-duplication. First name, last name, phone, job title, LinkedIn URL, and address fields transfer as direct text fields. Custom fields on the Apollo contact migrate to HighLevel contact custom fields. The Apollo contact's original create date is preserved as a custom datetime field in HighLevel.
Apollo ERP
Account
HighLevel
Company
1:1Apollo accounts map to HighLevel companies. Domain and website fields transfer directly. Industry, employee count, and LinkedIn company URL from Apollo require custom fields in HighLevel since industry and headcount are not standard HighLevel company fields. Multi-branch accounts (parent-child) are flattened to one company record per unique account ID in Apollo.
Apollo ERP
Deal
HighLevel
Opportunity
1:1Apollo deals migrate as HighLevel opportunities. The deal name maps to the opportunity name. The deal amount maps to the opportunity value field. Pipeline stage names map to HighLevel pipeline stage names, which must be pre-created in HighLevel before migration. Probability percentages are applied per stage based on Apollo stage configuration or a default mapping provided by the customer.
Apollo ERP
Task
HighLevel
Task
1:1Apollo tasks map directly to HighLevel tasks. Subject, body, due date, completion status, and owner assignment all transfer. Completed tasks preserve their completion timestamp. Task type (call, email, note) is stored as a custom field in HighLevel if type differentiation is needed for reporting.
Apollo ERP
Sequence
HighLevel
Workflow (no equivalent — rebuild required)
1:1Apollo sequences are a workflow-design artifact with step timing, A/B variants, and cadence controls that have no direct equivalent in HighLevel. We export the sequence definition (step order, email templates, delay intervals) as a reference document. HighLevel's Workflows engine must be rebuilt using that reference. Contacts enrolled in sequences are preserved as contacts — the enrollment state is not migratable and must be re-enrolled manually or via a Workflow trigger.
Apollo ERP
Contact Custom Field
HighLevel
Contact Custom Field
1:1Apollo custom fields on contacts migrate as HighLevel contact custom fields. Type mapping: Apollo string/text → HighLevel text; Apollo number → HighLevel number; Apollo date → HighLevel date; Apollo boolean → HighLevel checkbox; Apollo dropdown → HighLevel dropdown. HighLevel must create these custom fields in the Contact custom field section before migration runs. Field-level validation rules are not transferred.
Apollo ERP
Account Custom Field
HighLevel
Company Custom Field
1:1Apollo custom fields on accounts migrate as HighLevel company custom fields using the same type mapping as contact custom fields. Industry and employee count from Apollo's standard account fields are also stored as company custom fields since HighLevel does not have those as built-in company fields.
Apollo ERP
Deal Custom Field
HighLevel
Opportunity Custom Field
1:1Apollo custom fields on deals migrate as HighLevel opportunity custom fields. These are created separately from contact and company custom fields — HighLevel maintains strict object separation between contact, company, and opportunity custom fields. The migration plan must identify which opportunity custom fields exist per deal before data lands.
Apollo ERP
Enrichment Data (employment history, intent signals, buying triggers)
HighLevel
Custom fields or notes on Contact (reference only)
1:1Apollo's enrichment engine stores employment history, intent signals, and buying triggers per contact. These are Apollo-proprietary and have no native equivalent in HighLevel. We store the most recent enrichment snapshot as a read-only text custom field or contact note for reference. Full re-enrichment requires a third-party integration or manual process in HighLevel.
Apollo ERP
Contact-Account Association
HighLevel
Contact-Company Link
1:1Apollo's contact-account relationship (each contact linked to a primary account) maps to HighLevel's contact-company association. A contact in HighLevel can be linked to one primary company record plus additional associated companies. If Apollo contacts have multiple account associations, the most recently modified account is set as the primary in HighLevel.

Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Apollo ERP gotchas
Leave balance carry-forward errors on year-end migration
Chart of Accounts mapping requires manual chart design review
API rate limits throttle bulk export on lower-tier plans
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
Audit Apollo data model and HighLevel schema setup
FlitStack AI ingests your Apollo account's object structure, custom field definitions, pick-list values, and pipeline stage configuration. We compare this against your HighLevel sub-account's existing schema (contacts, companies, opportunities, custom fields) and surface gaps. The output is a schema setup checklist — a list of custom fields to pre-create in HighLevel, pipeline stages to define, and any pick-list value mappings that need manual confirmation before data lands.
Resolve owners and users by email match
Apollo owner IDs are matched to HighLevel users by email address. Unmatched owners are flagged with a pre-migration report — your team either creates the corresponding user in HighLevel before migration or assigns those records to a designated fallback owner. No record lands in HighLevel without a resolved assignedTo field. This step prevents orphaned records and ensures accountability is intact on day one.
Migrate accounts and contacts before deals and tasks
HighLevel requires accounts (companies) to exist before contacts can be linked via companyId, and requires contacts to exist before opportunities can reference them via contactId. FlitStack AI sequences the migration in dependency order: companies first, then contacts with their account associations resolved, then opportunities with their contact and company links resolved, then tasks with their contact links resolved. This ordering ensures every foreign key resolves correctly on the first pass without post-migration data repair.
Run a sample migration with field-level diff
A representative slice of records — typically 100–500 covering contacts, companies, opportunities, and tasks across multiple owners — migrates first. FlitStack AI generates a field-level diff comparing source Apollo values against destination HighLevel values for every mapped field. You verify enrichment data preservation, custom field mapping, stage name resolution, and owner assignment before the full run commits. Approval of the sample migration is required before the full dataset moves.
Cut over with delta pickup for in-flight records
The full migration commits against your HighLevel sub-account. During the cutover window (typically 24–48 hours), your team continues working in Apollo. FlitStack AI runs a delta pickup that captures any records created or modified in Apollo after the full migration timestamp. An audit log documents every record changed, and one-click rollback is available if reconciliation reveals unexpected data gaps. After delta pickup closes, Apollo is placed in read-only mode and HighLevel becomes the live CRM.
