Overview

What this migration involves

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.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

Atollon Lagoon CRM

What's pushing teams away

  • Very limited public API documentation means customers needing deep integrations or data portability hit a wall and look for alternatives with better developer resources.
  • The platform has stronger market presence in Czech and Central European markets; English-language support resources and documentation are thin for international teams.
  • With only three verified G2 reviews, independent signal on long-term reliability and feature trajectory is sparse — some buyers seek more validated platforms.
  • Organizations that grow beyond mid-market requirements often find the platform's feature set less extensible than global CRM leaders like Salesforce or HubSpot.
  • Limited third-party app marketplace compared to established CRMs means teams needing niche tools (specialised enrichment, advanced analytics) migrate elsewhere.

Choosing

HighLevel logo

HighLevel

What's pulling them in

  • Agencies choose HighLevel to consolidate CRM, email, SMS, scheduling, and funnels into one subscription, eliminating monthly bills for five to ten separate SaaS tools they previously stitched together.
  • The flat-rate pricing model bills per sub-account rather than per contact, so growing a contact database from 1,000 to 100,000 records does not trigger a billing surprise—a common pain point avoided by migrating customers.
  • White-label and sub-account capabilities let agencies resell HighLevel access to their own clients, turning a software cost center into a recurring revenue stream that justifies the subscription.
  • The platform ships a 14-day free trial with no credit card required, giving teams a low-friction entry point to validate fit before committing to the $97/month Starter tier.
  • Marketing agencies managing multiple client accounts use sub-accounts to maintain data isolation per client while operating under a single agency billing relationship with HighLevel.

Object mapping

How Atollon Lagoon CRM objects map to HighLevel

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)

maps to

HighLevel

Contact

1:1
Mapping required

Atollon 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)

maps to

HighLevel

Company

1:1
Mapping required

Atollon 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

maps to

HighLevel

Opportunity or Custom Object

1:many
Mapping required

Atollon 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

maps to

HighLevel

Task or Call/Email/Meeting

1:1
Fully supported

Atollon 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

maps to

HighLevel

Task or Opportunity Note

1:1
Mapping required

Atollon 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.

Atollon Lagoon CRM

Custom Forms (formvalue records)

maps to

HighLevel

Custom Fields on Contact, Company, Opportunity, Task

lossy
Fully supported

Atollon 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

maps to

HighLevel

Ticket

1:1
Mapping required

Atollon 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

maps to

HighLevel

Invoice (Custom Object or Quote)

lossy
Mapping required

Atollon 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.

Pair-specific challenges

  • Atollon has no publicly documented API — access must be verified before migration

    The platform provides no publicly accessible API documentation covering endpoints, authentication methods, or rate limits. We verify API access credentials and test connectivity during the discovery phase. Where the API is unavailable, unstable, or returns incomplete data, we fall back to structured CSV export supported by the platform's built-in data tools. This fallback may affect the maximum exportable record volume and requires additional validation time. We confirm the extraction method before migration scoping is finalised.

  • Custom form data requires formvalue-level parsing that adds normalisation steps

    Atollon stores custom form field values in separate formvalue records linked by formID and context, not directly on the parent Folder, Firm, Project, Activity, or Milestone object. 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 typed GoHighLevel custom fields. This normalisation step is not required for standard objects and adds processing time proportional to the number of formvalue records. We identify the distinct formIDs in scope during discovery and confirm the formvalue parsing plan before migration begins.

  • Project subtypes with different templates require subtype-aware mapping before import

    Atollon Projects span at least four subtypes — Contracts, Business cases, Service contracts, and Consultations — each potentially using different templates with different custom field sets. If all project subtypes are mapped to GoHighLevel Opportunities using a single schema, fields that only exist in one subtype's template may be dropped or misnamed on records from other subtypes. We handle subtype-aware mapping by first classifying each project by its template origin, then applying the corresponding field mapping schema. Projects without a clear template origin default to a generic mapping. We confirm the subtype inventory during scoping.

  • GoHighLevel sub-account structure requires location scoping before record import

    GoHighLevel agencies often operate multiple client sub-accounts (Locations) under a single account. Records migrated without a pre-assigned Location association land in the agency's master account by default, which can cause confusion for multi-client Atollon deployments where each Firm may represent a distinct client. We scope the Location structure during discovery, map each Atollon Firm to a corresponding GoHighLevel Location or the master account, and apply the Location ID during import. If the GoHighLevel plan does not include multi-location access (Starter tier), all records land in a single account by design.

  • Workflow Automations, Campaign Management, and ERP integration are not migratable

    Workflow Automation in Atollon is an Advanced-tier feature (EUR 496+/month) and Campaign Management is an Ultimate-tier feature — neither is exposed via API. GoHighLevel Workflows are a core platform feature available across all paid tiers with a different automation model. We do not migrate workflow rules as code. We deliver a written inventory of every Atollon automation rule and campaign with its trigger, conditions, and actions, plus a recommended GoHighLevel Workflow equivalent for the customer's admin to rebuild. ERP integration logic does not migrate.

Migration approach

Six steps for a successful Atollon Lagoon CRM to HighLevel data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

Source

Strengths

  • All-in-one CRM, project management, service, and finance reduces tool sprawl for professional services teams.
  • Custom forms on Folders, Projects, Activities, and Milestones allow administrators to extend the data model without code.
  • Active-user billing model — paying only for users who log in — differentiates from per-seat pricing for firms with variable team sizes.
  • Built-in team email, SMS, and phone integration within the CRM eliminates separate communication stack costs.
  • Cloud and desktop deployment options give customers flexibility on hosting preference.

Weaknesses

  • Extremely limited public API documentation — no publicly available developer reference, authentication method, or rate limits documented.
  • Very low independent review volume (3 verified G2 reviews) makes it difficult to assess real-world satisfaction with support and uptime.
  • Central European market focus means fewer English-language resources, community forums, and integration connectors than globally-distributed CRMs.
  • No documented bulk export or bulk API capabilities, which complicates large-volume data migration for customers switching platforms.
  • Workflow automations are not exposed via API — automation rules cannot be migrated and must be manually rebuilt in the destination system.

Destination

Strengths

  • Consolidates CRM, marketing automation, email, SMS, scheduling, and funnels into one platform at a predictable flat monthly rate.
  • Supports unlimited contacts and unlimited users on all paid tiers, removing per-record billing anxiety as databases grow.
  • Offers white-label and sub-account capabilities that let agencies resell access and manage multiple client environments under one billing relationship.
  • Includes built-in review management, reputation monitoring, and AI agents as native features rather than third-party add-ons.
  • Exports Contacts and Companies via a scalable async bulk CSV system that handles multi-million-row datasets without blocking the UI.

Weaknesses

  • The breadth of features creates a steep learning curve; advanced automations and Workflow configuration require significant time investment that smaller teams may not recover.
  • The platform charges usage-based fees for telecommunications and AI features that are not included in the base subscription, leading to bill surprises.
  • Recurring user reports on Reddit and G2 describe bugs, errors, and slow support response times that disrupt live marketing and sales operations.
  • Sub-account architecture, while powerful for agencies, adds migration complexity when identifying which client data lives in which isolated environment.
  • The platform is designed for agencies and SMBs; larger enterprises requiring deep reporting, custom objects at scale, or complex role-based access may outgrow its capabilities.

Most migrations land between three and five weeks for accounts under 15,000 Folders, 3,000 Firms, and 500 Projects with straightforward custom field structures and a single GoHighLevel Location. Migrations with multi-template project subtypes (Contracts, Business cases, Service contracts, Consultations), large engagement histories (over 200,000 Activities), complex formvalue parsing across multiple formIDs, or multi-location GoHighLevel sub-account structures move to seven to twelve weeks because of the subtype-aware mapping, formvalue normalisation, and Location dependency resolution work.
