Overview

What this migration involves

Moving from Corteza CRM to GoHighLevel is a migration from a self-hosted, open-source platform to a multi-tenant SaaS CRM built for agencies and SMBs. Corteza's module-based data model does not map one-to-one to GoHighLevel's Contact-Opportunity model, so we treat Corteza Leads as GoHighLevel Contacts with a lead_source tag, Corteza Accounts as GoHighLevel Locations attached to Contacts, and Corteza Opportunities as GoHighLevel Opportunities with stage mapping to GoHighLevel pipeline stages. Custom modules built in Corteza's low-code builder require a custom field strategy in GoHighLevel: personal attributes become Contact custom fields and deal-specific attributes become Opportunity custom fields. GoHighLevel distinguishes between these two types at creation and does not allow switching a field between objects after creation. We design the field partition during scoping and build the schema before any data moves. Workflows and automations from Corteza do not migrate as code; we deliver a written inventory of every active workflow for the customer's admin to rebuild in GoHighLevel's Automation builder.

Why teams make this switch

Two sides of the same decision

Leaving

Corteza CRM logo

Corteza CRM

What's pushing teams away

  • Enterprise support is unclear — despite Enterprise tier branding, there is no documented SLA or dedicated support channel, leaving self-hosted teams without recourse when issues arise.
  • Workflow stability after upgrades is inconsistent — lead conversion automation buttons have been documented as disabled after restore operations, requiring manual re-import of workflow definitions to fix.
  • The platform feels bare for production use — federation is marked experimental and disabled by default, and multiple standard CRM functions still require manual scripts or DB workarounds.
  • Self-hosting carries hidden operational cost — teams need DevOps capacity for deployment, backups, updates, and troubleshooting that SaaS CRMs absorb entirely.

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 Corteza CRM objects map to HighLevel

Each row shows how a Corteza 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.

Corteza CRM

Lead

maps to

HighLevel

Contact (with lead_source tag)

1:1
Fully supported

Corteza Leads are a first-class module with a separate conversion workflow. GoHighLevel does not have a separate Lead object; unqualified prospects are stored as Contacts. We migrate Corteza Leads as GoHighLevel Contacts and tag them with a lead_source custom field (value: 'Corteza Lead') so the customer's admin can identify converted versus non-converted records. If the Corteza instance used lead scoring, we map the score to a GoHighLevel Contact custom field. The Corteza conversion workflow (which creates Account, Contact, and Opportunity) is not migrated as code; we document the conversion logic for the admin to implement in GoHighLevel Automations.

Corteza CRM

Account

maps to

HighLevel

Contact (Location)

many:1
Fully supported

Corteza Accounts are standalone company records with industry, address, and social media fields that serve as the parent entity for Contacts. GoHighLevel has no explicit Account object; company information is stored as Location records attached to the primary Contact. We migrate each Corteza Account as a GoHighLevel Contact record representing the company (using the company name as the Contact name) with a Location record containing the address and industry. The original Contact records previously linked to the Account migrate as additional Contacts under the same Location.

Corteza CRM

Contact

maps to

HighLevel

Contact

1:1
Fully supported

Corteza Contacts represent individual people linked to a parent Account. We migrate these as GoHighLevel Contacts with the contact-account relationship preserved via Location linkage (the merged Account above). Standard fields (first name, last name, email, phone, job title) map directly to GoHighLevel Contact standard fields. Custom Contact fields from Corteza map to GoHighLevel Contact custom fields (see custom module note).

Corteza CRM

Opportunity

maps to

HighLevel

Opportunity

1:1
Fully supported

Corteza Opportunities track sales deals with stage, amount, probability, and close date linked to an Account. We map these to GoHighLevel Opportunities, using the merged Account Contact as the primary contact on the Opportunity. Corteza dealstage maps to a GoHighLevel Pipeline stage. We configure the GoHighLevel pipeline stages to match the Corteza stage names and probabilities before migration. Deal amount and expected close date migrate as Opportunity monetary_amount and expected_close fields.

Corteza CRM

Campaign

maps to

HighLevel

Contact (tag)

1:many
Fully supported

Corteza Campaigns group marketing activities and track CampaignMember responses linking Contacts and Leads. GoHighLevel does not have a native Campaign object; campaign membership is tracked via Tags, custom fields, and Pipeline stages. We migrate active Campaigns as GoHighLevel Tags on the relevant Contacts and Opportunities, preserving the campaign name as the tag value. CampaignMember status (sent, responded, bounced) migrates as a Contact custom field if the customer has active campaign tracking requirements.

Corteza CRM

Case

maps to

HighLevel

Opportunity (status tag)

1:many
Fully supported

Corteza Cases track customer support issues with status, priority, origin, and resolution linked to Accounts and Contacts. GoHighLevel's CRM is not a full service desk; support cases are typically tracked via Opportunities with status tags or via the built-in Tasks and Appointments. We migrate Cases as GoHighLevel Opportunities with a 'Support Case' pipeline or as tagged Tasks, depending on the customer's preferred tracking method chosen during scoping. Case priority and resolution details migrate as Opportunity custom fields.

Corteza CRM

Task

maps to

HighLevel

Task

1:1
Fully supported

Corteza Tasks can be standalone or related to any parent record (Lead, Account, Contact, Opportunity). Each task has status, due date, assignee, and description. We migrate Tasks as GoHighLevel Tasks with status (open, complete), due date, and description preserved. Task assignment migrates by resolving the Corteza assignee to a GoHighLevel User by email match. Parent-record linkage migrates via GoHighLevel's Opportunity and Contact lookup fields.

Corteza CRM

Event

maps to

HighLevel

Appointment

1:1
Fully supported

Corteza Events represent calendar items (meetings, calls) related to any CRM record, storing datetime, duration, organizer, and attendee references. We migrate Events as GoHighLevel Appointments with start time, end time, location, and description preserved. Attendee references migrate as related Contact lookups. Note that GoHighLevel's Appointment scheduling (Calendar feature) is separate from migrated Event records; we migrate the calendar content but do not configure GoHighLevel's Availability settings.

Corteza CRM

Custom Module (personal attributes)

maps to

HighLevel

Contact Custom Field

lossy
Fully supported

Corteza's low-code module builder can create entirely custom modules beyond the standard CRM set. Personal attributes (lead type, birthday, preferred contact method, referral source) that were stored in Corteza custom modules map to GoHighLevel Contact custom fields. We design the Contact custom field schema during scoping: field types are matched (text, number, date, dropdown) and fields are created in GoHighLevel before migration. Note: GoHighLevel Contact custom fields cannot be switched to Opportunity custom fields after creation, so the field partitioning decision is made during scoping.

Corteza CRM

Custom Module (deal attributes)

maps to

HighLevel

Opportunity Custom Field

lossy
Fully supported

Corteza custom modules storing deal-specific attributes (budget range, urgency, timeline to close, property type) map to GoHighLevel Opportunity custom fields. We create the GoHighLevel Opportunity custom fields before migration, matching Corteza field types to GoHighLevel supported types (text, number, date, dropdown, multi-select). The Opportunity custom fields appear within the Opportunity record and are used in pipeline views and Opportunity-level automations.

Corteza CRM

Files and Attachments

maps to

HighLevel

Contact / Opportunity attachments

1:1
Mapping required

Corteza file fields store attachments per module. GoHighLevel supports file attachments on Contacts and Opportunities via its native file storage. We extract files from Corteza module records and attach them to the corresponding GoHighLevel Contact or Opportunity records. Folder structure from Corteza does not map directly to GoHighLevel's flat file organization; files are attached without the original folder hierarchy. We flag any file attachment exceeding GoHighLevel's size limits for the customer's admin to handle separately.

Pair-specific challenges

  • Corteza namespace export fails on orphaned page references

    Corteza's namespace export path explicitly fails when any page in the namespace references a deleted module, preventing the 'take your entire CRM and move it' export from completing. We audit the namespace for orphaned page references before attempting export, clean up the broken page-module links, and then proceed with the namespace package so the migration does not stall at the export step. This audit is part of the discovery phase and must be resolved before data extraction begins.

  • GoHighLevel custom field type is locked at creation

    GoHighLevel distinguishes between Contact custom fields (personal attributes like birthday, preferred contact method) and Opportunity custom fields (deal-specific attributes like budget, timeline, property type). Once a field is created as one type, it cannot be switched to the other. If Corteza's custom modules mixed personal and deal attributes into a single custom module, we must partition them during scoping before migration. Migrations that skip this step end up with fields in the wrong context and require manual field deletion and recreation after the fact.

  • Corteza workflow automation does not migrate to GoHighLevel

    Corteza workflows automate CRM operations including lead conversion, quote creation, and task assignment, but these do not have a direct GoHighLevel equivalent and do not migrate as code. We deliver a written inventory of every active Corteza workflow with its trigger, conditions, actions, and recommended GoHighLevel Automation equivalent for the customer's admin to rebuild. The workflow inventory is captured during discovery before the migration window begins.

  • No publicly documented Corteza API rate limits

    Corteza does not publish API rate limit quotas in its public documentation. For bulk migration operations, this means we cannot pre-configure rate-limit-aware throttling without performing discovery requests against the specific instance. We start with conservative request pacing during extraction and monitor for HTTP 429 responses to dynamically adjust throughput. If the instance exhibits throttling behavior, we introduce exponential backoff and reduce batch sizes accordingly.

Migration approach

Six steps for a successful Corteza CRM to HighLevel data migration

  1. Discovery and instance audit

    We audit the source Corteza instance: namespace structure, module definitions, custom module field inventory, workflow list, active user count, and record volume across Leads, Accounts, Contacts, Opportunities, Campaigns, Cases, and Tasks. We also audit for orphaned page references that would block namespace export and document any file attachment volume. The discovery output is a written migration scope that defines the field partition between Contact and Opportunity custom fields in GoHighLevel, the pipeline stage mapping, and the workflow inventory requiring rebuild.

  2. GoHighLevel sub-account and schema design

    We create the GoHighLevel destination structure: sub-account provisioning (if managing multiple client locations), pipeline configuration with stages mapped from Corteza deal stages, Contact custom fields (from Corteza Leads and personal custom module attributes), and Opportunity custom fields (from Corteza Opportunities and deal-specific custom module attributes). We configure Location records to represent Corteza Accounts. Schema design is validated in a GoHighLevel sandbox or trial account before production migration begins.

  3. Corteza data extraction and file download

    We extract records from Corteza via the JSON API (authenticated via OIDC) in dependency order: Leads, Accounts (for Location merge planning), Contacts (with parent Account reference resolved), Opportunities (with Account and Contact lookups resolved), Campaign members, Cases, Tasks, Events, and custom module records. Files and attachments are downloaded from Corteza file fields. The orphaned page reference audit is performed against the namespace before extraction begins to avoid export stalls.

  4. Data transformation and field mapping

    We transform the extracted data: Corteza Leads become GoHighLevel Contacts tagged as leads; Corteza Accounts become GoHighLevel Contacts with Location records; Corteza Contacts attach to the corresponding Location; Corteza Opportunities map to GoHighLevel Opportunities with stage names aligned to the configured pipeline. Custom module attributes are partitioned into Contact or Opportunity custom fields based on the scoping decision. Email addresses are validated and deduplicated against existing GoHighLevel records if any pre-existing data exists.

  5. Production migration and reconciliation

    We run production migration in dependency order: Location records (from Corteza Accounts), Contact records (from Corteza Leads and Contacts with Location linked), Opportunities (with Contact and pipeline stage resolved), Campaign tags, Case records, Tasks, Events, and custom field values. Each phase emits a row-count reconciliation report. Files and attachments are uploaded to the corresponding Contact or Opportunity record. Owner assignment resolves by email match to GoHighLevel Users; any unmatched owners are flagged for admin provisioning.

  6. Cutover, validation, and workflow rebuild handoff

    We freeze Corteza writes during cutover, run a final delta migration of any records modified during the migration window, and hand off GoHighLevel as the system of record. We deliver the Corteza workflow inventory document with each workflow's trigger, conditions, and recommended GoHighLevel Automation equivalent. We do not rebuild workflows as GoHighLevel Automations inside the migration scope; that is a separate engagement or an internal admin task. We support a one-week hypercare window for reconciliation issues raised by the customer's team.

Platform deep dives

Context on both ends of the pair

Corteza CRM logo

Corteza CRM

Source

Strengths

  • 100% open-source with no per-user, per-contact, or tier-gated feature restrictions on the self-hosted version.
  • Self-hosted deployment gives complete data ownership and sovereignty over where customer data resides.
  • Low-code module builder lets non-developers create custom CRM objects and fields without writing code.
  • API-first design documented via OpenAPI with OIDC authentication for secure integrations.
  • Fine-grained RBAC with field-level read and update permissions for complex internal security policies.

Weaknesses

  • No documented SLA or dedicated enterprise support tier despite Enterprise tier branding — self-hosted teams rely on community forums.
  • Upgrade and restore events can break standard CRM workflow behavior, including lead conversion automation buttons.
  • Federation feature is marked experimental and disabled by default, limiting multi-instance identity management.
  • Self-hosted deployment requires DevOps resources for installation, configuration, backups, and ongoing maintenance.
  • Community-driven support has inconsistent response times compared to vendor-backed SaaS alternatives.

HighLevel

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.

Small Corteza instances under 10,000 Contacts, 2,000 Opportunities, and no custom modules typically complete in one to three weeks. Migrations with multiple custom modules, high file attachment volume, or additional Corteza modules (Campaigns, Cases, Contracts) extend to three to five weeks because of the custom field partitioning design work and multi-module sequencing. The timeline also depends on GoHighLevel sub-account configuration complexity and whether a sandbox validation step is required before production migration.
