Overview
Moving from Atollon Lagoon CRM to Nutshell is a migration from a Central European all-in-one platform with bundled projects, service, and finance into a focused SMB CRM with strong English-language documentation, a documented REST API, and a straightforward per-user pricing model. Atollon organizes individual contacts as Folders within a Firm database, stores custom form field values in separate formvalue records linked by formID, and has no publicly accessible API documentation. We resolve the Folder-to-Contact mapping, parse each formvalue record individually against its formID, and apply subtype-aware mapping for the four project subtypes (Contracts, Business cases, Service contracts, Consultations). Nutshell has no native Projects module, so Projects migrate as linked Note records with classification metadata or as a custom object if the Nutshell plan supports it. Workflow automations are Advanced-tier only in Atollon and are not exposed via API, so we document the automation inventory and provide a rebuild guide for Nutshell instead of migrating them as code.
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.

Object mapping
Each row shows how a Atollon Lagoon CRM object lands in Nutshell, 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)
Nutshell
People
1:1Atollon Folders classified as client, potential client, or partner map to Nutshell People records. We preserve the folder classification in a custom field on the Person record. Each Folder is resolved individually against its parent Firm (Company) reference to populate the Company link in Nutshell. The Folder's full name, email addresses, phone numbers, address fields, and any custom column values migrate directly.
Atollon Lagoon CRM
Firms (Companies)
Nutshell
Company
1:1Atollon Firms map to Nutshell Companies 1:1. We use the Firm name as the Company name and carry forward any custom classification columns, industry tags, and address data. A Company record is created first so that the People-to-Company relationship is satisfied at the moment of Person insert. Firms without a clear name default to a placeholder and are flagged for manual review post-migration.
Atollon Lagoon CRM
Projects
Nutshell
Note or Custom Object
1:manyNutshell has no native Projects module. We map Projects as Nutshell Notes with a classification prefix indicating the subtype (Contract, Business case, Service contract, Consultation) and a reference link back to the related Firm (Company) or Folder (Person). For customers on Nutshell Growth or higher plans, we can create a Project custom object with a subtype picklist, a Firm lookup, and custom fields carrying project-specific data. Projects without a clear template default to a generic Note mapping. Each project subtype is classified before mapping so that the correct field schema is applied.
Atollon Lagoon CRM
Activities
Nutshell
Activity Timeline
1:1Atollon Activities (calls, emails, meetings) linked to Folders or Firms migrate to Nutshell Activity records on the corresponding Person or Company. We preserve the activity type, timestamp, owner, direction (inbound/outbound), and body content. If Atollon stores call duration or meeting attendees, these migrate to custom fields on the Activity record. The activity ordering is preserved by setting the timestamp to the original Atollon Activity timestamp.
Atollon Lagoon CRM
Milestones
Nutshell
Task
lossyAtollon Milestones tracking timeline checkpoints within Projects or Activities map to Nutshell Tasks linked to the corresponding Note or Person/Company. Milestone order, due date, and completion status migrate as Task fields. Any custom field values on the Milestone are parsed via formvalue and mapped to Task custom fields.
Atollon Lagoon CRM
Custom Forms (formvalue records)
Nutshell
Custom Fields
lossyAtollon custom forms attached to Folders, Projects, Activities, or Milestones store field values in separate formvalue records linked by formID and context. We parse each formvalue record individually, resolve the field schema via the corresponding formID, and map each field value to a Nutshell custom field on the relevant object (Person, Company, or Note). Because the formvalue-to-form relationship is not always 1:1, we aggregate all formvalues for a given parent into a single set of custom field values, with multi-value fields migrated as comma-separated values or a custom text area.
Atollon Lagoon CRM
Service Support Records
Nutshell
Person or Case
1:1Atollon service and support ticket records map to Nutshell Cases if the customer is on a plan supporting Cases, or to Person records with a custom status field if Cases are not available. We preserve ticket status, priority, assigned agent reference, and the linked Firm/Project relationship as custom fields or linked Notes.
Atollon Lagoon CRM
Workflow Automations
Nutshell
None
1:1Workflow Automation in Atollon is an Advanced-tier feature gated at EUR 496/month and is not accessible via the public API. We do not migrate automation rules. We audit which automations existed during the scoping call, document the trigger, conditions, and actions for each, and provide a written rebuild guide mapped to Nutshell's workflow rule builder as part of the migration package.
Atollon Lagoon CRM
Campaign Records
Nutshell
Person Tags or Lists
1:1Atollon Campaign Management (Ultimate tier) records including campaign name, status, and linked targets migrate to Nutshell as a combination of Person tags and a linked Note describing the campaign. Marketing automation actions do not migrate; we provide a rebuild guide for any marketing sequences that existed in Atollon.

Migration approach
Scoping and export feasibility assessment
We audit the Atollon Lagoon CRM instance for Folders, Firms, Projects (with subtypes), Activities, Milestones, and custom forms. We verify API access credentials and test connectivity against the observed internal API patterns (CreateCustomForm, formID, context, formvalue). Where the API is inaccessible or returns incomplete data, we fall back to structured CSV export. We identify active-user count, active Workflow Automations count, and the form template inventory to scope the formvalue normalisation workload. The scoping output is a written migration scope document and an export feasibility report.
Destination schema design and custom field provisioning
We design the Nutshell destination schema. For each Folder field, we map to a corresponding Nutshell Person field or create a custom field on Person. For each Firm field, we map to a Company field or create a custom field on Company. For custom form fields, we create Nutshell custom fields on the relevant object (Person, Company, or Note), aggregating multi-value formvalue entries. For Projects, we configure either a Note-based structure with classification metadata or a custom object if the Nutshell plan supports it. We verify the destination plan's custom field limits against the total formvalue field count before provisioning.
Project subtype classification and formvalue parsing
We classify every Atollon Project by its template origin (Contract, Business case, Service contract, Consultation) before applying any field mapping. For each custom form, we parse every formvalue record, resolve the field schema via formID, and normalise the field values into a flat record keyed on the parent object. This step is the most Atollon-specific part of the migration and cannot be automated generically because the formvalue structure varies by form.
Firm-Folder dependency resolution and Company-Person import
Atollon Firms (Companies) and Folders (Contacts) have a dependency: Folders can reference a parent Firm. We export Firms first, create Nutshell Company records, then export Folders and create Person records with the Company relationship resolved. Owner reconciliation maps Atollon user references to Nutshell user accounts by email match. Any Owner without a matching Nutshell user is flagged for the customer's admin to provision before record import resumes.
Activity timeline and Milestone import
We import Activities (calls, emails, meetings) as Nutshell Activity records linked to the corresponding Person or Company. Milestones import as Tasks linked to the related Note or Person/Company. For large engagement volumes, we batch records and use Nutshell's API with rate-limit handling. Activity ordering is preserved by setting timestamps to the original Atollon Activity timestamps. Service support tickets import as Cases or Person-based records depending on the destination plan.
Cutover, validation, and automation rebuild handoff
We freeze Atollon writes during the cutover window, run a final delta migration of any records modified during the migration period, then designate Nutshell as the system of record. We validate record counts in Nutshell against the Atollon export totals and spot-check 20-30 records for field-level accuracy. We deliver the Workflow Automation inventory and rebuild guide to the customer's admin team. We do not rebuild Atollon Workflows as Nutshell workflow rules inside the migration scope; that work is documented for the admin to configure post-migration.
