Overview
Moving from EspoCRM to GoHighLevel is a structural migration from an open-source, self-hosted CRM with a separate Accounts and Contacts model to a multi-channel marketing and sales platform where Companies are a field on Contact. EspoCRM's Entity Manager custom entities map to GoHighLevel Custom Objects (up to 10 per location as of the October 2025 release), and the association relationships are rebuilt as GoHighLevel object links. We extract from EspoCRM's paginated REST API (200-record ceiling) and load via GoHighLevel's Contacts API and bulk import endpoints. Activity history (calls, meetings, tasks, emails) migrates to GoHighLevel Tasks and the activity timeline. Files attached to self-hosted EspoCRM records are extracted from the server filesystem and re-uploaded to GoHighLevel's Media Library, with file URLs stored in custom fields on the relevant records. EspoCRM Workflows, BPM extensions, and any PHP-based custom scripts do not migrate; we deliver a written inventory of every active automation for the customer's admin to rebuild in GoHighLevel's Workflow builder.

Object mapping
Each row shows how a EspoCRM 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.
EspoCRM
Contact
HighLevel
Contact
1:1EspoCRM Contacts map to GoHighLevel Contacts. The EspoCRM firstName and lastName split maps to GoHighLevel's firstName and lastName; email, phone, and address fields map 1:1. Custom fields on EspoCRM Contacts (including multi-enum fields capped at 20 options) migrate to GoHighLevel Contact custom fields. If the EspoCRM Contact has a linked Account, the Account name populates the GoHighLevel Company field on the Contact record.
EspoCRM
Account
HighLevel
Contact (Company field)
many:1EspoCRM Accounts map to GoHighLevel Company values stored on the Contact record rather than a separate Account object. We extract each distinct EspoCRM Account name, deduplicate, and map the Account-Contact relationship by writing the Account name into the GoHighLevel Contact's Company field. If the customer requires a dedicated company-level record in GoHighLevel for reporting, we discuss a Custom Object for Accounts as an optional configuration step.
EspoCRM
Lead
HighLevel
Lead
1:1EspoCRM Leads map directly to GoHighLevel Leads. Lead status, source, and assigned user fields migrate. The EspoCRM lead type and any custom lead classification fields map to GoHighLevel Lead custom fields. Note that EspoCRM's Lead conversion (which creates a Contact and Account) does not apply during data migration; we preserve the Lead as-is and the customer decides whether to convert in GoHighLevel post-migration.
EspoCRM
Opportunity
HighLevel
Opportunity
1:1EspoCRM Opportunities map to GoHighLevel Opportunities. Deal amount maps to Opportunity Value, stage maps to Pipeline stage, close date maps to Close Date, and probability maps to a custom field (GoHighLevel Opportunities do not have a native probability field but one can be added as a custom number field). The Opportunity-Contact link (primary contact on deal) maps to GoHighLevel's Opportunity contact association.
EspoCRM
Pipeline (Opportunity stage)
HighLevel
Pipeline + Stage
lossyEspoCRM Opportunity stages map to GoHighLevel Pipeline stages. We extract the stage names and order from EspoCRM, create corresponding Pipelines in GoHighLevel, and assign stage names and ordering to match the source. Each EspoCRM pipeline becomes a separate GoHighLevel Pipeline within the Opportunities module.
EspoCRM
Case
HighLevel
Task or Custom Object
lossyEspoCRM Cases (support tickets) have no native GoHighLevel equivalent. We evaluate the customer's Case usage and map to either GoHighLevel Tasks (if Cases are primarily activity tracking) or a Custom Object named Cases with fields for status, priority, subject, and related Contact. The customer chooses the strategy during scoping based on whether Cases are used for ticket management or light activity tracking.
EspoCRM
Campaign
HighLevel
Campaign
1:1EspoCRM Campaigns map to GoHighLevel Campaigns. Campaign name, status, type, and start/end dates migrate. GoHighLevel Campaigns support linking to Contacts for tracking campaign membership. Note that email send history and email engagement metrics from EspoCRM do not migrate because GoHighLevel Campaign tracking starts fresh on the new platform.
EspoCRM
Activity: Call
HighLevel
Task (Call)
1:1EspoCRM Call activities map to GoHighLevel Tasks with the type set to Call. Call duration, disposition, and related Contact reference migrate. The original call date populates the Task due date for timeline ordering. Call recordings (stored as attachments on self-hosted EspoCRM) are extracted from the filesystem and uploaded to GoHighLevel Media Library, with the file URL stored in a custom field on the Task record.
EspoCRM
Activity: Meeting
HighLevel
Appointment
1:1EspoCRM Meeting activities map to GoHighLevel Appointments. Meeting title, start and end datetime, location, and related Contact or Opportunity reference migrate. The original meeting date and time are preserved in the Appointment record. Attendee information migrates as notes on the Appointment if the customer requires attendee history.
EspoCRM
Activity: Task
HighLevel
Task
1:1EspoCRM Task activities map to GoHighLevel Tasks with the type set to Task. Status (completed, not completed), priority, due date, and assigned user migrate. The original task date preserves activity timeline ordering in GoHighLevel's contact record timeline.
EspoCRM
Activity: Email
HighLevel
Activity Timeline Entry
1:1EspoCRM email activities migrate as timeline entries in GoHighLevel Contacts. Email subject, body, direction (sent or received), and timestamp migrate. The full email body is stored in a custom field or note attached to the Contact record. Note that GoHighLevel's email deliverability runs on shared Mailgun infrastructure (LC Email); we flag this in the gotchas and advise warming a dedicated sending domain post-migration.
EspoCRM
Custom Entity (Entity Manager)
HighLevel
Custom Object
1:1EspoCRM Entity Manager custom entities map to GoHighLevel Custom Objects. We extract the entity definition metadata (field types, labels, relationships) during discovery, create the corresponding Custom Object schema in GoHighLevel (field types mapped: text to text, varchar to short text, int to number, decimal to number, date to date, datetime to datetime, enum to dropdown, multi-enum to multi-select, link-multiple to association). Up to 10 Custom Objects per location are available on all GoHighLevel plans as of the October 2025 release. Cross-entity relationships map to GoHighLevel object associations (1:1, 1:N, or N:N).
EspoCRM
Document (Attachment)
HighLevel
Media Library + Custom Field
lossyEspoCRM Documents and attachments on self-hosted instances are stored on the server filesystem under data/files/. We extract the referenced files during migration, upload each file to GoHighLevel's Media Library via the API, and store the resulting file URL in a custom field on the parent record (Contact, Opportunity, or Custom Object). File names and original upload dates are preserved in the custom field label. For cloud-hosted EspoCRM, attachments are referenced via the Attachment entity and migrated as file URL custom fields in GoHighLevel.
EspoCRM
User
HighLevel
User
1:1EspoCRM Users map to GoHighLevel Users by email match. We extract the EspoCRM user list (name, email, role, team membership) and match against GoHighLevel Users created during the account setup phase. Any EspoCRM User without a matching GoHighLevel User goes to a reconciliation queue for the customer's admin to provision. Role and team mapping is documented in the migration inventory for manual configuration in GoHighLevel's team settings.

Pair-specific challenges
Migration approach
Discovery and EspoCRM API audit
We audit the source EspoCRM instance across entity types (standard and custom via Entity Manager), record counts per entity, custom field definitions, pipeline and stage configuration, user list, and attachment volume. For self-hosted instances, we also assess the server filesystem for attachment storage location and estimate file transfer scope. The discovery output is a written migration scope document listing every entity to migrate, the target mapping, and any entities that will not migrate (workflows, BPM extensions, PHP scripts) with a rebuild inventory delivered separately.
Schema design for GoHighLevel Custom Objects
We design the GoHighLevel destination schema before any data moves. This includes creating any Custom Objects needed for EspoCRM Entity Manager entities, defining custom fields on Contact, Lead, and Opportunity with types mapped from EspoCRM field definitions, configuring Pipelines and Stages to match EspoCRM Opportunity stages, and defining Custom Object associations (1:1, 1:N, N:N) to replicate EspoCRM link-multiple relationships. For Case records, we present the customer with a choice between Task-based or Custom Object-based mapping and configure accordingly.
Sandbox migration and reconciliation
We run a full migration into a GoHighLevel test environment using production-like data volume. The customer's team reconciles record counts, spot-checks 20-30 random records against the EspoCRM source (verifying field values, linked records, and activity timestamps), and validates the Custom Object schema. Any field mapping corrections, custom field type adjustments, or association configuration issues surface here before production migration begins.
Attachment extraction and Media Library upload
For self-hosted EspoCRM instances, we extract all files from the server filesystem under data/files/ that are referenced by Attachment records. Files are organized by parent entity (Contact, Opportunity, Custom Object) and uploaded to GoHighLevel's Media Library via the API. The returned file URLs are staged in a mapping table that is applied during the record import phase. Cloud-hosted EspoCRM instances do not require filesystem extraction; attachment references are extracted from the Attachment API entity and mapped directly.
Production migration in dependency order
We run production migration in record-dependency order: GoHighLevel Users (validated against EspoCRM user list by email), Leads, Accounts mapped to Contact Company fields, Contacts (with Account/Company resolved), Opportunities (with Contact and Pipeline stage resolved), Custom Objects (in topological order for cross-referencing entities), Activities (Calls, Meetings, Tasks, Emails mapped to GoHighLevel Tasks and Appointments), Campaigns, and Case records mapped to the chosen strategy. File URLs from the attachment mapping table are written to custom fields on each parent record. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, validation, and automation rebuild handoff
We freeze EspoCRM writes during cutover and run a final delta migration of any records modified during the migration window. We validate the GoHighLevel data in production (record counts, spot-checks on 25-50 records, pipeline stage distribution, custom object record counts) and hand off the written automation inventory to the customer's admin team. We support a 72-hour hypercare window where we resolve any data issues raised by the customer's team. Workflow rebuild in GoHighLevel's Workflow builder is outside migration scope; the inventory document provides the mapping guidance for the admin team.
