Overview
Migrating from RETAINUSER CRM to GoHighLevel is a migration between two SMB-focused platforms with different architectural philosophies. RETAINUSER combines Leads and Contacts under one record model; GoHighLevel uses a unified Contact object with no separate Lead concept, meaning any RETAINUSER Lead records must be merged into Contact during import. RETAINUSER's absence of a public API means exports rely on UI-based data extraction and bulk downloads rather than programmatic API pulls, which adds time to the scoping phase. We resolve owner lookups by email match, map RETAINUSER pipeline stages to GoHighLevel pipeline stages, and preserve activity history as Notes and Tasks linked to the correct Contact. Workflows and automations from RETAINUSER are documented as a structured specification and handed off for rebuild in GoHighLevel's Automation builder, which uses a trigger-action model that differs from RETAINUSER's rule engine.

Object mapping
Each row shows how a RETAINUSER CRM 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.
RETAINUSER CRM
Lead
HighLevel
Contact
1:manyRETAINUSER captures leads via Facebook Forms, WhatsApp, and manual entry. GoHighLevel has no separate Lead object; all prospects live as Contacts. We migrate RETAINUSER Lead records as GoHighLevel Contacts, preserving lead source, lead status, and assignment owner. The lead-to-contact distinction is stored as a custom field on the GoHighLevel Contact (e.g., original_record_type__c) for reporting segmentation after migration.
RETAINUSER CRM
Contact
HighLevel
Contact
1:1RETAINUSER Contact records map 1:1 to GoHighLevel Contacts. Standard fields (first name, last name, email, phone, address) migrate directly. Custom properties on RETAINUSER Contacts require field-level mapping; we extract the custom field schema including field type and picklist values, then pre-create GoHighLevel Contact custom fields of matching type before import. GoHighLevel locks field type at creation, so this must be resolved in the schema design phase before any data loads.
RETAINUSER CRM
Company
HighLevel
Organization
1:1RETAINUSER Company records map to GoHighLevel Organizations. The Organization is created before Contact import so that the Organization ID field can be populated on each Contact during the Contact load phase. Contact-to-company linkage is preserved by exporting RETAINUSER's association table and reconstructing it as Organization ID references in GoHighLevel. If RETAINUSER Company records lack an assigned contact, the Organization migrates independently and the association is rebuilt where a contact-company relationship is established by the customer during reconciliation.
RETAINUSER CRM
Deal
HighLevel
Opportunity
1:1RETAINUSER Deals map to GoHighLevel Opportunities. Each RETAINUSER pipeline becomes a GoHighLevel Pipeline, and each stage within that pipeline becomes a GoHighLevel Stage. Deal fields (value, currency, owner, expected close date, stage) map to Opportunity equivalents. Stage names require explicit mapping because RETAINUSER stage names differ from GoHighLevel stage names; we extract the full stage name list during discovery and configure the GoHighLevel pipeline with matching names or equivalent stages per the customer's preference.
RETAINUSER CRM
Pipeline
HighLevel
Pipeline
lossyRETAINUSER supports multiple pipelines with configurable stages. We extract the full pipeline configuration including stage order, stage names, stage probabilities, and win/loss criteria. Each RETAINUSER pipeline becomes a GoHighLevel Pipeline created under the Opportunities section before Deal migration begins. GoHighLevel pipelines are configured in Settings > Opportunities > Pipelines, and the Opportunity record references the correct Pipeline ID at insert time.
RETAINUSER CRM
Activity: Email
HighLevel
Note
1:1RETAINUSER email engagements (logged emails against a Contact or Deal) migrate to GoHighLevel Notes attached to the relevant Contact. We preserve email subject, body content, sender, recipient, and timestamp. The Note body carries the email text. Notes are linked to the Contact via the Note's contact association. If the email is associated with a Deal, the Note is linked to the associated Opportunity's Contact record for traceability.
RETAINUSER CRM
Activity: Call
HighLevel
Task (Call subtype)
1:1RETAINUSER call logs migrate to GoHighLevel Tasks with a call disposition field. We preserve call duration, call outcome, owner, and the original timestamp as the Task's due date. The Task is linked to the Contact who was the call subject. Call recording URLs stored in RETAINUSER are noted as a custom field reference for the customer admin to re-link if the recording storage system supports post-migration URL updates.
RETAINUSER CRM
Activity: Meeting
HighLevel
Task (Meeting subtype)
1:1RETAINUSER meeting logs migrate to GoHighLevel Tasks with meeting details preserved in the task description. Meeting title, attendees, date, and location map to task fields. The Task is linked to the relevant Contact. If RETAINUSER stores attendee email addresses, we include them in the task notes for the GoHighLevel admin to re-invite in the new calendar integration post-migration.
RETAINUSER CRM
Activity: Note
HighLevel
Note
1:1RETAINUSER standalone notes (not attached to an engagement type) migrate to GoHighLevel Notes linked to the relevant Contact or Organization. Note content migrates as plain text. Attachments on notes are exported as individual files and re-uploaded to GoHighLevel as file attachments on the relevant record. Note timestamps are preserved to maintain the activity timeline sequence.
RETAINUSER CRM
User / Owner
HighLevel
User
1:1RETAINUSER Users map to GoHighLevel Users by email match. We extract all distinct owners referenced on Contact, Company, Deal, and Activity records and cross-reference against GoHighLevel User accounts by email address. Users without a matching GoHighLevel account go to a reconciliation queue for the customer's admin to provision before the migration window. Inactive RETAINUSER users are flagged for archive rather than active-seat migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
RETAINUSER CRM gotchas
No public API documentation for direct export
Workflow automations are not directly portable
Email/SMS template merge field syntax differs from destination CRMs
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 export scope confirmation
We audit the source RETAINUSER account across record volume (Contacts, Companies, Deals, Activities), custom field schema, pipeline count, active workflows, and export format availability. Because RETAINUSER has no public API, we confirm the export options available under the customer's current plan tier (bulk CSV download, per-object export, attachment export). We also confirm the GoHighLevel destination account setup and whether a single account or sub-account structure applies. The discovery output is a written scope document with record counts, field mapping table, pipeline stage list, and workflow inventory request.
Schema design in GoHighLevel
We design the GoHighLevel destination schema before any data moves. This includes creating all required custom fields (with the correct Contact vs Opportunity type assignment locked in GoHighLevel before import), configuring Pipelines and Stages matching the RETAINUSER pipeline structure, and setting up Organization records for later Contact linkage. Pipeline stage names are mapped explicitly from RETAINUSER to GoHighLevel equivalents, with the customer confirming stage name choices during a design review call. Schema is deployed in a GoHighLevel sandbox or staging account first for validation.
Data audit and cleansing
We audit the RETAINUSER data for duplicates, incomplete records, and inconsistent formats before migration. Duplicate Contacts (same email) are flagged for merge or archive. Contacts and Companies missing required fields (name, email) are flagged for the customer to complete or accept as partial records. Phone number formats are standardized to a consistent format. This step reduces post-migration data quality issues and ensures the GoHighLevel import does not carry forward problems that existed in RETAINUSER.
Record migration in dependency order
We migrate in record-dependency sequence: Organizations first (from RETAINUSER Companies), then Contacts (from RETAINUSER Leads and Contacts merged into GoHighLevel Contacts with Organization ID resolved), then Opportunities (from RETAINUSER Deals with Pipeline and Stage resolved). Owner resolution happens throughout by email match against GoHighLevel User accounts, with unresolved owners flagged in a reconciliation queue. Activity history (emails, calls, meetings, notes) migrates as Notes and Tasks linked to the relevant Contact record after the Contact base layer is confirmed complete.
Validation and reconciliation
We run reconciliation against the source RETAINUSER data: record counts per object, spot-checks on 25 to 50 randomly sampled records for field-level accuracy, pipeline stage distribution match, and activity timeline completeness. The customer reviews the reconciliation report and raises any discrepancies before cutover. GoHighLevel's built-in reporting views are used for spot validation against the RETAINUSER source data. Any field mapping corrections are applied and the affected records are re-imported before the production cutover window.
Cutover and workflow handoff
We freeze writes to RETAINUSER during the cutover window, run a final delta migration of any records modified during the migration window, then confirm GoHighLevel as the system of record. We deliver the migration summary report including record counts, mapping decisions, and any unmigrated data (e.g., attachments in formats not supported for re-upload). We deliver the written workflow inventory document listing every RETAINUSER automation with trigger, conditions, and actions for rebuild in GoHighLevel's Automation builder. Post-migration, FlitStack AI does not provide ongoing admin support, training, or workflow rebuild; these are separate engagements.
