Overview
Moving from Atollon Lagoon CRM to GoHighLevel is a structural migration for a Central European professional services platform shifting to a North American all-in-one agency and SMB CRM. Atollon organises contacts as Folders within a Firm database and stores custom form field values in separate formvalue records linked by formID; we parse those records individually and map them to GoHighLevel custom fields. Projects span multiple subtypes (Contracts, Business cases, Service contracts, Consultations) with different template schemas; we classify each by its template origin and apply the correct field mapping before import. Atollon has no publicly documented API, so we verify access credentials during scoping and fall back to structured CSV export when the API is unavailable. Workflow Automations, Campaign Management, and any ERP integration logic do not migrate; we deliver a written rebuild guide for GoHighLevel workflows as part of the migration package.
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 Atollon Lagoon 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.
Atollon Lagoon CRM
Folders (Contacts)
HighLevel
Contact
1:1Atollon Folders with client, potential client, partner, or other classification columns map to GoHighLevel Contacts. The Folder's custom classification column maps to a Contact tag or custom field in GoHighLevel depending on whether the classification is a simple label or a structured value. Folder-level custom forms attached via formID and formvalue records are parsed individually; each formvalue field is mapped to a GoHighLevel Contact custom field with the field type resolved from the form schema. The migration resolves Folder-to-Firm parentage before import so that the contact's company association is set correctly.
Atollon Lagoon CRM
Firms (Companies)
HighLevel
Company
1:1Atollon Firms map to GoHighLevel Companies. The Firm's custom classification column (client, potential client, partner) maps to a GoHighLevel Company tag or custom field. Firm address data maps to GoHighLevel's address fields (street, city, state, postal_code, country). Any custom form data attached to the Firm via formvalue records is parsed against the formID and mapped to Company custom fields.
Atollon Lagoon CRM
Projects
HighLevel
Opportunity or Custom Object
1:manyAtollon Projects span at least four subtypes — Contracts, Business cases, Service contracts, and Consultations — each using different templates with potentially different custom field sets. We classify each project by its template origin, then apply the correct mapping schema. Projects with a generic template default to a generic mapping. In GoHighLevel, projects map to Opportunities using the pipeline stage to represent project status, with subtype recorded in a custom Opportunity field. If the customer has more than four project subtypes with materially different schemas, we discuss creating GoHighLevel custom objects for each subtype rather than forcing all project data into the Opportunity object.
Atollon Lagoon CRM
Activities
HighLevel
Task or Call/Email/Meeting
1:1Atollon Activities (calls, emails, meetings, tasks) linked to Folders or Firms map to GoHighLevel Tasks. Email activities land as Tasks with the email body preserved; call activities land as Tasks with TaskSubtype=Call and duration preserved; meeting activities land as Tasks with meeting type noted. Activity timestamps and owner references migrate directly. We resolve the Activity's parent Folder or Firm reference to the corresponding GoHighLevel Contact or Company lookup.
Atollon Lagoon CRM
Milestones
HighLevel
Task or Opportunity Note
1:1Atollon Milestones track timeline checkpoints within Projects or Activities. They may carry custom form data via formvalue records. We map Milestones preserving their order, due date, and any custom field values. Milestones with simple date and status map to GoHighLevel Tasks; Milestones with complex custom form data map to Task custom fields. Parent-project lookup is resolved to the corresponding GoHighLevel Opportunity at migration time.

Custom Forms (formvalue records)
HighLevel
Custom Fields on Contact, Company, Opportunity, Task
lossyAtollon custom form values are stored in formvalue records linked to the parent object by formID and context. The relationship between form and formvalue is not always 1:1 — one parent record may have multiple formvalues from different form schemas. We parse each formvalue record individually, resolve the field schema via formID, and map field-level values to GoHighLevel custom fields of the corresponding type. This normalization step is required for every custom form attached to Folders, Firms, Projects, Activities, and Milestones, and adds processing time proportional to the number of formvalue records in the dataset.
Atollon Lagoon CRM
Service Support Records
HighLevel
Ticket
1:1Atollon service and support module manages ticket-like records. We map these to GoHighLevel Tickets, preserving status, priority, assigned agent, and linked Firm and Project references. Ticket thread history migrates as a linked activity log or note on the Ticket record. The service agent assignment resolves against the GoHighLevel User table by email match.
Atollon Lagoon CRM
Invoices and Billing Records
HighLevel
Invoice (Custom Object or Quote)
lossyAtollon invoices linked to Projects or Firms migrate as Invoice records. We map invoice header data, line items, amounts, and status. Detailed financial history migration depends on the GoHighLevel plan tier and whether invoices are handled via a native integration (QuickBooks, Stripe) or as custom objects. The customer chooses the invoice strategy during scoping. Invoice PDFs are not migratable as attachments in the standard scope; we document the invoice record count and field set for manual handoff.

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.
Atollon Lagoon CRM gotchas
Active-user billing scoping on import
No publicly documented API for programmatic export
Custom form data requires formvalue-level parsing
Project templates and subtypes need subtype-aware mapping
Workflow Automations are tier-gated and non-portable
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 extraction method confirmation
We audit the Atollon Lagoon CRM instance across Folders, Firms, Projects (by subtype), Activities, Milestones, custom forms (formIDs in scope), service support records, and invoice data. We verify API access credentials and test connectivity; if the API is unavailable or returns incomplete data, we switch to structured CSV export via the platform's built-in data tools. We identify the distinct formIDs and their field schemas, the project subtype inventory, and the active-user count to scope GoHighLevel plan requirements. The discovery output is a written migration scope with record counts per object, extraction method, and a GoHighLevel plan recommendation based on Location requirements.
GoHighLevel sub-account and schema design
We design the GoHighLevel destination schema based on the Atollon data audit. This includes creating custom Contact, Company, Opportunity, and Ticket fields to receive Atollon custom form data, configuring Location (sub-account) structure to match the Atollon Firm hierarchy, mapping Atollon project subtypes to GoHighLevel pipeline stages or custom objects, and defining the formvalue-to-custom-field mapping for each formID in scope. If the customer has more than four materially different project subtypes, we propose a custom object per subtype rather than overloading the Opportunity object. Schema is reviewed and approved before any data is written.
GoHighLevel Location and user provisioning
We extract every distinct Atollon user referenced on Folder, Firm, Project, Activity, and Milestone records and map them to GoHighLevel Users by email match. We confirm the GoHighLevel Location assignment for each Atollon Firm and ensure that the customer's GoHighLevel plan supports the required Location count. Users without a matching GoHighLevel account go to a reconciliation queue for the customer's admin to provision before record import. Migration cannot proceed past this step because Location associations are required for all CRM record imports in GoHighLevel.
Sandbox migration and reconciliation
We run a full migration into GoHighLevel using a sandbox or a shadow account. The customer's admin reconciles record counts (Contacts in, Companies in, Opportunities in, Tasks in, Tickets in), spot-checks 25-50 records against the Atollon source for field accuracy, and validates that the formvalue-sourced custom fields populated correctly on each object type. The custom form mapping, project subtype mapping, and Location assignments are all validated here. Sign-off on the sandbox migration precedes the production migration date.
Production migration in dependency order
We run production migration in record-dependency order: Companies (from Atollon Firms), Contacts (with Location resolved and custom fields populated from formvalue records), Opportunities (with pipeline stage mapped by project subtype), Tasks and Activities (with parent Contact or Company lookup resolved), Milestones (with parent Opportunity lookup resolved), Tickets (with status, priority, and linked Company resolved), and Invoices (if in scope and mapped to custom objects or quotes). Each phase emits a row-count reconciliation report before the next phase begins. Where the Atollon API is unavailable, we use the validated CSV export method with the same dependency order.
Cutover, validation, and automation rebuild handoff
We freeze Atollon writes during cutover, run a final delta migration of any records modified during the migration window, then set GoHighLevel as the system of record. We deliver the Workflow and Campaign automation inventory document with recommended GoHighLevel Workflow equivalents to the customer's admin team. We support a one-week hypercare window to resolve reconciliation issues raised by the team. We do not rebuild Atollon Workflow Automations as GoHighLevel Workflows inside the migration scope; that is a separate engagement or an internal admin rebuild task.
