Overview
Moving from MiniCRM to GoHighLevel is a structural migration across platforms with different data models and different export constraints. MiniCRM uses Cards as the primary record container with Contacts, Companies, and Deals (called Interests) as linked sub-objects; GoHighLevel separates Contacts from Opportunities and supports Custom Objects for non-standard data. The primary migration challenge is MiniCRM's sparse API documentation and lack of bulk export tooling, which requires us to request CSV exports during discovery and work around the undocumented export endpoint. Automation rules (Automatyzacje) cannot be exported at all and must be documented during discovery for the customer to rebuild in GoHighLevel's Workflow builder. We map MiniCRM custom fields on Cards to GoHighLevel Contact Custom Fields or Opportunity Custom Fields depending on the Card's record type, and we handle Polish-language labels by working with the customer's team during the mapping phase to confirm field meanings.
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 MiniCRM 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.
MiniCRM
Card (Karta)
HighLevel
Contact + Opportunity (conditional split)
1:manyMiniCRM Cards are the primary record container and may hold both person-level details and deal information. We split at migration time: Card fields that are person attributes (name, email, phone, address) map to GoHighLevel Contact; Card fields that describe a sale (deal value, stage, expected close date) map to GoHighLevel Opportunity. The split rule is defined during scoping based on the customer's Card structure. The original MiniCRM Card ID is preserved in a custom field minicrm_card_id__c for reconciliation.
MiniCRM
Contact (Kontakt)
HighLevel
Contact
1:1MiniCRM Contact sub-records map directly to GoHighLevel Contact. Standard fields (name, email, phone, address) migrate cleanly. We use email as the dedupe key during import. If a Contact sub-record has no email, we use first name + last name as the dedupe criterion.
MiniCRM
Company (Firma)
HighLevel
Contact (company info fields) or Custom Object
1:1MiniCRM Company records hold business-level data. GoHighLevel does not have a native Company/Account object separate from Contact, so company details (company name, industry, website, size) migrate to the primary Contact record's company-related fields. If the customer uses Companies as standalone entities linked to multiple Contacts, we recommend creating a Custom Object called Company in GoHighLevel and linking Contacts via a lookup relationship.
MiniCRM
Deal / Interest (Interes)
HighLevel
Opportunity
1:1MiniCRM Deals (called Interests) map to GoHighLevel Opportunities. The deal value, pipeline stage name, expected close date, and associated owner migrate. MiniCRM pipeline stages are mapped to GoHighLevel pipeline stages during schema setup. We resolve the parent Contact reference at migration time.
MiniCRM
Pipeline Stage (Etap)
HighLevel
Pipeline Stage
lossyMiniCRM pipeline stages map to GoHighLevel pipeline stages. We create the GoHighLevel pipeline before migration, define stage names that match the customer's MiniCRM stage names, and set stage probabilities. Stage ordering is preserved from MiniCRM.
MiniCRM
Task (Zadanie)
HighLevel
Task
1:1MiniCRM Tasks migrate to GoHighLevel Task. Due date, status, assignee (resolved via User mapping), and description transfer directly. Recurrence patterns and reminder settings do not export and are flagged for manual configuration in GoHighLevel.
MiniCRM
Note (Notatka)
HighLevel
Note
1:1MiniCRM Notes attached to Cards migrate as GoHighLevel Notes linked via ContentDocumentLink to the parent Contact or Opportunity. Note body transfers as rich text. We preserve the association to the original Card for reconciliation.
MiniCRM
Custom Field (Pole dodatkowe)
HighLevel
Contact Custom Field or Opportunity Custom Field
lossyMiniCRM custom fields on Cards migrate to GoHighLevel Contact Custom Fields (for person attributes) or Opportunity Custom Fields (for deal attributes). Field types are mapped: text to text, number to number, date to date, choice/dropdown to dropdown. Choice field values are mapped individually to the GoHighLevel dropdown options during schema setup.
MiniCRM
Automation Rule (Automatyzacja)
HighLevel
Workflow (not migrated)
lossyMiniCRM automation rules cannot be exported via API. We document every active automation during discovery with its trigger, conditions, actions, and execution order. The customer rebuilds these in GoHighLevel's Workflow builder. We prioritize documenting revenue-impacting sequences (deal stage triggers, follow-up emails) first.
MiniCRM
User / Worker (Pracownik)
HighLevel
User
1:1MiniCRM Users map to GoHighLevel Users. We resolve by email match. Any MiniCRM User without a matching GoHighLevel User is held in a reconciliation queue for the customer's admin to provision before record import resumes.
MiniCRM
Calendar / Event
HighLevel
Appointment / Calendar Event
1:1MiniCRM calendar events linked to Cards migrate as GoHighLevel Appointments. Event title, date, time, and linked Contact transfer. Full attendee lists and calendar-specific metadata require supplemental mapping during scoping.
MiniCRM
Tag / Label
HighLevel
Tag
1:1Tags applied to MiniCRM Cards for segmentation migrate as GoHighLevel Tags on the corresponding Contact or Opportunity. We deduplicate tags during import to avoid recreating messy taxonomy in the new system.

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.
MiniCRM gotchas
Automation rules do not export via API
Pricing tier boundaries are opaque
API export tooling is limited and undocumented
Acquisition by group.one may affect product continuity
Polish-language interface and documentation
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 assessment
We audit the MiniCRM account for record counts (Cards, Contacts, Companies, Deals, Tasks, Notes), active automation rules, custom field definitions, and user list. We assess the available export path given MiniCRM's undocumented bulk API. If CSV exports are available via the platform UI, we request them during discovery. If not, we flag manual export preparation as a required customer task before migration begins. We also confirm the GoHighLevel plan tier and assess whether Custom Objects are needed for Company-to-Contact mapping.
Schema design and Polish field translation
We design the GoHighLevel destination schema including pipeline stages (matching MiniCRM Interest stages), Contact Custom Fields and Opportunity Custom Fields (mapped from MiniCRM Card custom fields), and Custom Objects if the customer uses Companies as standalone linked entities. We work with the customer's team to translate Polish-language field labels and automation rule descriptions into English equivalents for the GoHighLevel schema. This step produces a written field mapping document that the customer reviews and approves before any data moves.
Automation rule documentation
We document every active MiniCRM automation rule during discovery with its trigger event, conditions, actions, and execution order. We categorize them by business impact and deliver a written automation inventory with recommended GoHighLevel Workflow equivalents. The customer uses this document to rebuild automations in GoHighLevel post-migration. This step is manual and requires the customer's admin to participate in a discovery call or provide screen recordings of their active rules.
User reconciliation and GoHighLevel provisioning
We extract every distinct MiniCRM User referenced on Cards, Tasks, and Deals and match by email against the GoHighLevel destination's User table. Any MiniCRM User without a matching GoHighLevel User goes to a reconciliation queue. The customer's GoHighLevel admin provisions missing Users before record import resumes. Owner assignment on migrated records depends on this step being complete.
Record migration in dependency order
We run migration in record-dependency order: Users (validated), Contacts (from MiniCRM Contact sub-records), Companies (mapped to Contact company fields or Custom Object), Opportunities (with Contact link resolved and pipeline stage mapped), Tasks (with owner resolved), Notes (linked to parent Contact or Opportunity), and Tags (applied to Contacts and Opportunities). Each phase emits a row-count reconciliation report before the next phase begins. We use GoHighLevel's CSV import for Contact and Opportunity bulk loads with custom field mapping applied during the transform step.
Cutover, validation, and automation rebuild handoff
We freeze MiniCRM 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 the automation inventory document and support the customer through a one-week hypercare window for reconciliation issues. We do not rebuild MiniCRM Automatyzacje as GoHighLevel Workflows inside the migration scope; that work is documented for the customer's admin and is a separate engagement if specialized configuration is needed.
