Overview
Moving from Concord CRM to GoHighLevel is a shift from a self-hosted, one-time-license platform to a cloud-native, all-in-one SaaS CRM with monthly subscription pricing. Concord organizes data around Contacts, Companies, Deals, Products, and Activities exportable via CSV or REST API. GoHighLevel uses a Locations model for businesses and a Contact record that flattens Concord's separate Company-to-Contact relationship into a location-based link. We export Concord's Companies first, then Contacts with their company_id resolved to GoHighLevel Location IDs, then Deals mapped to GoHighLevel Opportunities in the configured pipeline. Concord's Activities (calls, meetings, tasks) migrate as GoHighLevel Tasks and Calendar Events. Concord Workflows do not fire during data import and are not migrated; we deliver a written inventory of every active automation for GoHighLevel rebuild. Attachments stored in Concord's storage/app directory require manual file-system export and re-upload to GoHighLevel Media Library. The migration timeline for a typical long_tail dataset lands between two and four weeks.

Object mapping
Each row shows how a Concord 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.
Concord CRM
Company
HighLevel
Location
1:1Concord CRM Companies map to GoHighLevel Locations, which serve as the account-level record. The Company name becomes the Location name, domain becomes the website field, and any address fields map to the Location address block. GoHighLevel Locations can represent a single business or multiple branch locations; Concord's single-company installations map to one primary Location. Company export must run first because Concord Contacts reference company_id as a foreign key that we resolve to a GoHighLevel Location ID before Contact import.
Concord CRM
Contact
HighLevel
Contact
1:1Concord Contacts map to GoHighLevel Contacts with the Concord company_id resolved to the corresponding GoHighLevel Location ID. Each Contact's email, phone, address, and custom field values transfer directly. Concord's contact type or tags map to GoHighLevel Contact tags. We deduplicate by email address and flag any records with the same email for the customer to resolve before import completion.
Concord CRM
Deal
HighLevel
Opportunity
1:1Concord Deals map to GoHighLevel Opportunities inside a configured Pipeline. The Deal stage name maps to a GoHighLevel Pipeline stage; Deal value maps to the Opportunity amount; expected_close_date maps to the GoHighLevel close date field. Concord Deal associations (linked contact and company) map to the GoHighLevel Contact and Location lookups on the Opportunity record.
Concord CRM
Pipeline Stage
HighLevel
Pipeline Stage
lossyConcord CRM exports pipeline stages as deal properties but does not include pipeline metadata in the export. We extract the distinct stage values from Deal records, create corresponding stages in the target GoHighLevel Pipeline before migration, and assign stage names and order to match Concord's sequence. If Concord uses multiple pipelines, we create multiple GoHighLevel Pipelines and map each Deal to the appropriate pipeline by comparing pipeline IDs from Concord's export data.
Concord CRM
Product
HighLevel
Product
1:1Concord Products (name, price, SKU, description) map to GoHighLevel Products. GoHighLevel Products are used in Pipeline items and can be attached to Opportunities. Product migration is straightforward because Concord Products have no foreign key dependencies on other exported objects.
Concord CRM
Activity
HighLevel
Task or Calendar Event
1:manyConcord Activities (calls, meetings, tasks, notes) with a type of 'call' map to GoHighLevel Tasks with task_type=Call and call duration preserved. Activities of type 'meeting' map to GoHighLevel Calendar Events. Tasks map to GoHighLevel Tasks. We reconstruct the association back to the parent Contact or Deal using the Concord linked_resource_type and linked_resource_id fields, resolving these to GoHighLevel Contact and Opportunity IDs via the lookup tables built during earlier migration phases.
Concord CRM
Custom Field
HighLevel
Custom Field
lossyConcord CRM custom fields (boolean, date, select, text, number, UUID-keyed in API) map to GoHighLevel custom fields with equivalent types. Boolean fields from Concord map to GoHighLevel True/False fields; date fields map to Date fields; select fields map to Dropdown fields with the source picklist values replicated as options; number fields map to Number fields. We configure all GoHighLevel custom fields before any Contact, Company, or Deal import begins.
Concord CRM
User
HighLevel
User
1:1Concord CRM does not include a native export feature for Users and Roles. We retrieve user data via the Concord REST API (email, name, role assignment) for mapping purposes. GoHighLevel Users are provisioned by email invite by the customer's admin; we provide a user mapping table cross-referencing each Concord user email to the target GoHighLevel user email so that Deal assignments and Activity ownership resolve correctly during migration.
Concord CRM
Attachment
HighLevel
Media Library
1:1Concord CRM does not include a document attachment export feature in the standard export tool. Attachments stored in the Concord server's storage/app directory must be exported manually via file system access (SFTP or direct server file access) and re-uploaded to GoHighLevel's Media Library. We coordinate the file export as a separate step with the customer's IT contact, provide a file-to-record mapping table linking each exported file to the corresponding GoHighLevel Contact or Deal record, and the customer re-uploads files manually or via GoHighLevel's Media Library API.

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.
Concord CRM gotchas
Workflows do not fire during data import
Self-hosted data export requires role permission
API pagination cap at 100 records per page
Domain transfer requires full server migration
CSRF headers cause API auth failures
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 export permission setup
We audit the Concord CRM instance: record counts for Contacts, Companies, Deals, Products, and Activities; custom field definitions and types; active workflow configurations; and pipeline stage names. We confirm export permissions with the customer's admin and assign the export permission to the API token user if not already enabled. We retrieve user data via the Concord API for owner mapping. The output is a written migration scope document covering record counts, custom field inventory, and workflow count.
GoHighLevel pipeline and schema configuration
Before any data moves, we configure the destination GoHighLevel environment: create Pipelines matching Concord's deal stage sequence, create Locations (the GoHighLevel account-level record), configure custom fields matching Concord's custom field types, and set up Contact tags corresponding to Concord's contact types or groups. GoHighLevel's schema must be live and ready before import begins because GoHighLevel's import tools reference existing pipeline IDs and custom field IDs.
Companies export and Location seeding
We export Concord Companies first (as required by the relational export order) and import them as GoHighLevel Locations. Company name maps to Location name; address fields map to the Location address block; domain maps to the website field. We generate a Concord company_id to GoHighLevel Location ID lookup table used to resolve Contact associations in the next step. Row counts are reconciled against Concord export totals before proceeding.
Contacts export with Location resolution
We export Concord Contacts and resolve each contact's company_id against the Concord company ID in the lookup table built in Step 3, inserting the corresponding GoHighLevel Location ID on each Contact import. Custom field values transfer to the matching GoHighLevel custom fields. Concord contact tags map to GoHighLevel Contact tags. We run deduplication by email and flag duplicates for customer resolution.
Deals, Products, and Activities import
Concord Deals import as GoHighLevel Opportunities inside the configured Pipeline, with Deal stage mapped to the corresponding Pipeline stage, amount mapped to Opportunity value, and linked Contact and Company resolved via the lookup tables. Products import as GoHighLevel Products. Activities (calls, meetings, tasks) import as GoHighLevel Tasks and Calendar Events with parent Contact and Opportunity IDs resolved from the lookup tables. Each object phase emits a row-count reconciliation report.
Cutover, file export handoff, and automation rebuild guide delivery
We freeze Concord writes during cutover, run a final delta migration of records modified during the migration window, then enable GoHighLevel as the system of record. We deliver the Concord file export mapping to the customer's IT contact for manual Media Library re-upload. We deliver the written Workflow inventory and GoHighLevel rebuild guide for the customer's admin to reconstruct automations. We provide a one-week post-cutover support window for reconciliation issues. We do not rebuild Concord Workflows as GoHighLevel Workflows within the migration scope.
