Overview
Moving from ZeyOS to GoHighLevel is a migration from a unified ERP/CRM/Groupware platform to a marketing-focused CRM built for agencies and service businesses. ZeyOS stores business data across Accounts, Contacts, Leads, Items, Projects, Tasks, Tickets, Contracts, and financial records in a PostgreSQL-backed system with a REST API that lacks a bulk endpoint. We paginate through ZeyOS records individually, handle audit-locked invoices by sequencing them in strict chronological order, and convert Unix epoch timestamps to ISO 8601 strings before GoHighLevel import. GoHighLevel uses Contacts as the primary person record with tag-based segmentation and pipeline-based opportunity management, which requires us to transform ZeyOS's project-centric task hierarchy into GoHighLevel's contact-centric workflow model. We do not migrate ZeyOS iXML scripts, ERP inventory transactions, or ZeyOS workflows as code; we deliver a written inventory of these for the customer's admin to rebuild in GoHighLevel's automation builder.
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 ZeyOS 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.
ZeyOS
Account
HighLevel
Contact (company field) + Location
1:1ZeyOS Accounts map to GoHighLevel Contacts with the company name stored in the Contact's Company field and a GoHighLevel Location record created for address and phone data. The Location record preserves the ZeyOS account's primary address, billing address, and contact phone numbers. We use the account's external ID from ZeyOS as a custom GoHighLevel field for reconciliation after import.
ZeyOS
Contact
HighLevel
Contact
1:1ZeyOS Contacts map directly to GoHighLevel Contacts with name, email, phone, and the parent Account link preserved via the Company field. The ZeyOS extdata fields (nickname, custom address fields) migrate as GoHighLevel custom properties with type inference from the ZeyOS fields table schema. Any ZeyOS Contacts without an email are flagged for manual review because GoHighLevel's import process requires an email or phone for deduplication.
ZeyOS
Lead
HighLevel
Contact (tagged as Lead)
1:manyZeyOS Leads are a distinct object from Contacts and carry lead-specific status fields. We map ZeyOS Leads to GoHighLevel Contacts and apply a migration-specific tag (e.g., 'migrated-lead') plus the original ZeyOS lead status as a custom property. The customer decides during scoping whether to keep migrated Leads as GoHighLevel Contacts or use GoHighLevel's pipeline/opportunity model for lead-stage tracking.
ZeyOS
Item
HighLevel
Product
1:1ZeyOS Items (inventory and product catalog with barcode, model, and custom fields) map to GoHighLevel Products. Stock quantities from ZeyOS's automated inventory system do not migrate because GoHighLevel has no native inventory management. We store the last known stock quantity as a custom Product property and flag the absence of live inventory sync for the customer's admin to address via Zapier or a dedicated inventory integration.
ZeyOS
Project
HighLevel
Opportunity or Custom Project Object
lossyZeyOS Projects with Tasks, subtasks, and time entries require restructuring in GoHighLevel. For service businesses, we map Projects to GoHighLevel Opportunities with a custom Project Name field and Tasks as GoHighLevel Tasks linked to the Contact. For project-management-heavy teams, we pre-create a GoHighLevel Custom Object named 'Project' with lookups to Contact and custom fields for project status, budget, and dates. The customer selects the model during scoping.
ZeyOS
Task
HighLevel
Task
1:1ZeyOS Tasks belonging to Projects map to GoHighLevel Tasks with assignee, due date, and status preserved. Parent-Project linkage is maintained by adding the GoHighLevel Opportunity or Custom Project ID as a custom Task field since GoHighLevel Tasks do not have a native Project lookup. ZeyOS custom workflow flags on Tasks migrate as GoHighLevel Tags or custom task properties.
ZeyOS
Ticket
HighLevel
Opportunity (support pipeline) or Custom Ticket Object
lossyZeyOS Tickets (Helpdesk with email integration and subject-line ticket numbering) map to GoHighLevel as either a separate pipeline stage within the Opportunities object or as a GoHighLevel Custom Object named 'Ticket' with Status, Priority, and linked Contact. We recommend the Custom Object approach if the customer needs a separate support queue from their sales pipeline.
ZeyOS
Contract
HighLevel
Custom Contract Object or Opportunity
1:1ZeyOS Contracts (subscription or service agreements tied to Accounts) map to a GoHighLevel Custom Object named 'Contract' with Account lookup, start/end dates, and contract value. Contract terms and renewal rules require manual rebuild in GoHighLevel; we deliver the contract metadata and a written recommendation for renewal reminder workflows using GoHighLevel's automation builder.
ZeyOS
User
HighLevel
User
1:1ZeyOS Users (team members who own records and create files) map to GoHighLevel Users by email match. We resolve ZeyOS user_id to GoHighLevel User ID for owner assignments on Contacts, Opportunities, and Tasks. Inactive ZeyOS users are flagged for deactivation review in GoHighLevel before migration begins.
ZeyOS
Quote, Order, Delivery, Invoice
HighLevel
Custom Financial Objects
1:1ZeyOS's five financial objects (Quotes, Orders, Deliveries, Invoices) form a billing pipeline that GoHighLevel does not natively replicate. We create GoHighLevel Custom Objects for each financial type with line items, totals, dates, and status. Audit-locked ZeyOS invoices are sequenced in strict chronological order before import and flagged if any are out of sequence, because locked records cannot be modified or deleted via the ZeyOS API after booking.
ZeyOS
Activity (calls, emails, meetings, notes)
HighLevel
Activities via GoHighLevel API
1:1ZeyOS Activities (engagements linked to Accounts or Contacts) map to GoHighLevel Contacts with timeline entries. Calls migrate as GoHighLevel call log entries; emails as activity notes; meetings as calendar events with the Contact linked. We use GoHighLevel's REST API to insert activities in chronological order to preserve the timeline sequence. Note attachments migrate as GoHighLevel documents linked to the Contact.
ZeyOS
Time Entry
HighLevel
Custom Time Entry Object or Task
1:1ZeyOS Time Entries (billable or non-billable hours against Projects, Tasks, or Tickets) map to a GoHighLevel Custom Object named 'TimeEntry' with linked Contact, Project reference, date, hours, and description. If the customer uses GoHighLevel's built-in task tracking, time entries attach as custom fields on the relevant Task.
ZeyOS
Document (files table)
HighLevel
Document
1:1ZeyOS files stored in the files table with binary blobs in the binfile column are downloaded individually via the ZeyOS REST API and re-uploaded to GoHighLevel Documents linked to the parent Contact, Opportunity, or Project record. Files exceeding 25MB are flagged for customer review before import because GoHighLevel has documented upload size limits. We validate MIME types and convert non-standard formats as needed.
ZeyOS
Custom Fields (fields table extdata)
HighLevel
Custom Properties
lossyZeyOS custom fields exposed via the fields table and extdata JSON pattern in the REST API are read as field definitions and mapped to GoHighLevel custom properties with equivalent data types. Multi-select, date, number, and text field types map directly; ZeyOS-specific types are inferred from the extdata structure. We create the GoHighLevel custom properties before any data import so that the destination fields exist during record insertion.

Pair-specific challenges
Migration approach
Discovery and ZeyOS API audit
We audit the source ZeyOS instance via its REST API at cloud.zeyos.com/{INSTANCE}/api/v1/ covering all object types (Accounts, Contacts, Leads, Items, Projects, Tasks, Tickets, Contracts, Documents, Users, Quotes, Orders, Deliveries, Invoices, Time Entries, Activities), custom field definitions from the fields table, file attachment count and total blob size, and the invoice chronology for any audit-locked records. We produce a written scope document with record counts, data quality flags, and a recommendation on whether to use GoHighLevel native objects or custom objects for ZeyOS's ERP-layer records.
GoHighLevel schema design and custom object provisioning
We design the GoHighLevel destination schema before any data moves. This includes creating custom objects for ZeyOS ERP-layer records (Contracts, Financial objects, Time Entries) that have no native GoHighLevel equivalent, configuring custom properties on Contact to receive ZeyOS extdata fields, designing the project model (Opportunity-based or Custom Project object), and defining the migration-specific tag taxonomy for ZeyOS Leads. Schema is created in GoHighLevel's test environment first for validation.
Financial object chronology validation and invoice sequencing
We extract the full invoice history from ZeyOS and validate that records are in strict chronological order by booking date. Any invoices with out-of-sequence booking dates are flagged for customer review because they cannot be modified or deleted post-booking in ZeyOS. We provide the customer with a written chronology report and require sign-off before proceeding to invoice import. This step is a prerequisite for the financial object migration phase.
Test migration into GoHighLevel staging environment
We run a full migration into GoHighLevel's staging or sandbox environment using production-like data volume. The customer reconciles record counts, spot-checks 25-50 records for data accuracy (name spelling, email validity, phone formats, date values, file attachment presence), and reviews the custom object structures. Any mapping corrections happen in this phase. We do not proceed to production migration without written customer sign-off on the test migration results.
Production migration in dependency order
We run production migration in record-dependency order: Users (validated against GoHighLevel User list), Accounts (with Locations), Contacts (with Company linkage), Leads (with migration tags), Items (as GoHighLevel Products without inventory), Projects (as Opportunities or Custom Projects per the agreed model), Tasks (with parent linkage), Tickets, Contracts, Financial objects (Quotes, Orders, Deliveries, Invoices in chronological sequence), Activities, Time Entries, and Documents (binary blobs). Each phase emits a reconciliation report before the next phase begins.
Cutover, delta sync, and automation inventory delivery
We freeze ZeyOS writes during cutover, run a final delta migration of any records modified during the migration window, then enable GoHighLevel as the system of record. We deliver a written inventory of every ZeyOS workflow, iXML script, and automation rule with a description of its purpose and recommended GoHighLevel automation equivalent. We support a 72-hour hypercare window where we resolve any reconciliation issues raised by the customer's team. We do not rebuild ZeyOS workflows as GoHighLevel automations inside the migration scope; that is a separate engagement.
