How long does a MiniCRM to HubSpot migration take?

Most MiniCRM-to-HubSpot migrations complete in 48–72 hours of clock time for under 50,000 records across contacts, companies, and deals. Larger setups with over 200,000 records or extensive custom field mapping extend to 5–10 days. HubSpot's requirement to sequence the migration (Companies before Contacts, Contacts before Deals) adds planning overhead. Polish-language field validation and diacritic normalization also extend timeline for data with non-ASCII characters.

Will my MiniCRM workflows and automations migrate to HubSpot?

No. FlitStack AI migrates data and schema only — MiniCRM automations, triggers, and notification rules do not migrate to HubSpot Workflows. MiniCRM's trigger-action model (status-change emails, deadline notifications, task assignments) has a fundamentally different architecture than HubSpot's enrollment-based workflow engine. We export your MiniCRM automation definitions as a reference document for your HubSpot admin to rebuild in HubSpot's workflow builder. Plan 1–2 hours per workflow for manual rebuild.

What does MiniCRM deal status become in HubSpot?

MiniCRM deal stages (Nowe, W trakcie, Wygrane, Przegrane) map via value mapping to HubSpot dealstage pick-list values scoped per pipeline. Wygrane maps to Closed Won; Przegrane maps to Closed Lost; Nowe and W trakcie map to your defined early and mid-stage values in the target HubSpot pipeline. Original MiniCRM stage names are preserved in a custom property (Original_Deal_Stage__c) for audit continuity.

Can I migrate MiniCRM custom fields to HubSpot custom properties?

Yes. MiniCRM custom fields per module (contacts, companies, deals, tasks) map to HubSpot custom properties on the corresponding object. Field types (text, number, date, picklist, multi-select) translate to HubSpot property types. Custom fields that have no HubSpot standard equivalent are created as custom properties before migration. We deliver a custom property creation checklist so your HubSpot admin can pre-create the schema before data lands.

What happens to MiniCRM tasks in HubSpot?

MiniCRM tasks become HubSpot Tasks or Engagements. Tasks with a due date and assignee map to HubSpot Tasks with status (NOT STARTED, COMPLETED). Tasks linked to a contact or deal with note content become HubSpot note Engagements on the contact or deal timeline. Task owner resolves by email match to HubSpot users; unmatched assignees are flagged before migration.

Does the migration affect my MiniCRM account during cutover?

No. FlitStack AI uses scoped read access on MiniCRM via API export or CSV download — your team keeps working in MiniCRM during migration. A delta-pickup window (24–48 hours) captures any records created or modified in MiniCRM during the cutover so HubSpot reflects MiniCRM's final state at go-live. MiniCRM remains fully operational until you decommission it post-migration.

How are MiniCRM tags and labels handled in HubSpot?

MiniCRM tags on contacts or deals have no native HubSpot equivalent. We migrate tags as a custom multi-picklist property (Tag__c) on the corresponding HubSpot object. Your HubSpot admin can then use these tags in filters, workflows, or views. Alternatively, tags can be mapped to HubSpot association labels if your HubSpot plan supports custom association types.

Why do my MiniCRM contacts need a primary company in HubSpot?

HubSpot's Contact object requires a primary company lookup (Contact → Company) for association logic, reporting, and email routing. MiniCRM allows multiple companies per contact without enforcing a primary link. We migrate the most-recently-modified company as primary and surface additional companies in HubSpot's Company Contact Associations table. This preserves the full association graph while satisfying HubSpot's schema requirement.

MiniCRM to HubSpot Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

MiniCRM's card-based model stores contacts, companies, deals, tasks, and notes in a flat structure optimized for small teams managing straightforward sales processes. HubSpot's CRM uses a richer object graph with Contacts, Companies, Deals, and Tickets — each with standard properties, custom properties, and association labels. The migration carries everything MiniCRM stores natively (contact details, company records, deal amounts and stages, tasks with due dates, and notes) into HubSpot's object model. The key translation points are: MiniCRM's deal status values map to HubSpot deal stages per pipeline; MiniCRM's task records become HubSpot engagements or tasks; owner email resolution ties MiniCRM users to HubSpot users; and MiniCRM's simple tagging model maps to HubSpot properties or association labels. Workflows, automations, and notification rules do not migrate — those must be rebuilt in HubSpot Workflows. FlitStack sequences the migration via HubSpot's API (Contacts → Companies → Deals) to preserve foreign-key relationships, runs a sample migration with field-level diff, and captures in-flight changes during a 24–48 hour delta window.

Why teams make this switch

Two sides of the same decision

Leaving

MiniCRM

What's pushing teams away

Pricing structure is opaque and not clearly communicated — a G2 reviewer explicitly noted difficulty understanding what they were paying for and which features were included at their tier.
Limited advanced features as the team scales — power users outgrow the platform's capability ceiling for complex pipelines, custom objects, and integrations.
Recent acquisition by group.one introduces uncertainty — customers on review platforms express concern about product direction, support continuity, and whether pricing or terms may change.
Polish-language documentation and support — non-Polish speakers may find help resources and customer support limited when troubleshooting migration-related issues.
Lack of bulk API tooling — teams with large datasets report difficulty exporting data efficiently, making migration projects more manual and time-consuming.

Choosing

HubSpot

What's pulling them in

Lowest barrier to entry of any major CRM — the free tier with unlimited contacts lets teams validate fit before committing to a paid plan, according to G2 and Capterra reviewers.
Native integration between the CRM and sales engagement tools (sequences, email tracking, dialer) means no separate sync configuration, a theme across G2 Sales Hub reviews.
Pipeline visualization, deal tracking, and automated workflows are consistently praised as intuitive and easy to set up without developer involvement.
Strong onboarding for new team members — reviewers on Capterra and G2 highlight how quickly new reps become productive without formal training.
The HubSpot platform ecosystem (Marketing, Sales, Service, CMS hubs) allows growing companies to consolidate tools without building new integrations.

Object mapping

How MiniCRM objects map to HubSpot

Each row shows how a MiniCRM object lands in HubSpot, including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

MiniCRM

Contact (Osoba)

maps to

HubSpot

Contact

1:1

Fully supported

MiniCRM contact fields (name, email, phone, company link, address, job title) map directly to HubSpot Contact properties. HubSpot requires a primary company lookup (Contact → Company); contacts without a company link in MiniCRM receive a placeholder 'No Company' association.

MiniCRM

Company (Firma)

maps to

HubSpot

Company

1:1

Fully supported

MiniCRM company records map to HubSpot Companies. Company name, domain, industry, phone, and address fields translate directly. MiniCRM's flat company structure maps to HubSpot's hierarchical model where parent-company relationships use the Parent Company field.

MiniCRM

Deal (Interes)

maps to

HubSpot

Deal

1:1

Fully supported

MiniCRM deals (interesy) map to HubSpot Deals with deal name, amount, close date, and owner. Deal stage in MiniCRM (Nowe, W trakcie, Wygrane, Przegrane) translates via value mapping to HubSpot dealstage pick-list values scoped per pipeline.

MiniCRM

Task (Zadanie)

maps to

HubSpot

Task / Engagement

1:1

Fully supported

MiniCRM tasks map to HubSpot Tasks or Engagements depending on type. Tasks with a due date and assignee become HubSpot Tasks; tasks linked to a contact or deal with a note become Engagements on the timeline. Task status (open, completed) maps to HubSpot task status.

MiniCRM

Note (Notatka)

maps to

HubSpot

Engagement (Note)

1:1

Fully supported

MiniCRM notes attached to contacts, companies, or deals become HubSpot Timeline Engagements of type 'note'. Original timestamps and author (owner) are preserved. HubSpot's note format supports rich text.

MiniCRM

Tag / Label

maps to

HubSpot

HubSpot Property (custom)

1:1

Fully supported

MiniCRM tags on contacts or deals have no native HubSpot equivalent. Tags migrate as a custom multi-picklist property (e.g., Tag__c) or as association labels depending on your HubSpot plan and admin preference.

MiniCRM

Owner (Pracownik)

maps to

HubSpot

HubSpot User

1:1

Fully supported

MiniCRM owner IDs resolve by email match against HubSpot users. Unmatched owners are flagged before migration; you either invite them to HubSpot first or reassign their records to a fallback HubSpot user.

MiniCRM

Custom Field (Pole niestandardowe)

maps to

HubSpot

Custom Property

1:1

Fully supported

MiniCRM custom fields per module (contacts, companies, deals) map to HubSpot custom properties on the corresponding object. Field types (text, number, date, picklist) translate to HubSpot property types. Multi-select picklists in MiniCRM become HubSpot multi-picklist properties.

MiniCRM

Activity History (calls, emails)

maps to

HubSpot

Engagement (call, email)

1:1

Fully supported

MiniCRM records of calls and emails linked to contacts become HubSpot Engagements with type 'call' or 'email'. Original timestamps, duration, and owner are preserved. MiniCRM's email body text migrates as engagement metadata.

MiniCRM

File Attachment

maps to

HubSpot

HubSpot File

1:1

Fully supported

MiniCRM file attachments on contacts, companies, or deals re-upload to HubSpot Files and associate to the corresponding record. File size limits apply per HubSpot plan. Inline images in notes are downloaded and rehosted.

MiniCRM

MiniCRM Workflow / Automation

maps to

HubSpot

HubSpot Workflow (rebuild required)

1:1

Fully supported

MiniCRM automations (status-change triggers, email notifications, task assignments) do not migrate to HubSpot. We export your MiniCRM automation definitions as a rebuild reference. HubSpot Workflows must be created from scratch using HubSpot's workflow builder.

Pair-specific challenges

MiniCRM deal stages require value-by-value mapping to HubSpot pipeline stages

MiniCRM's flat deal stage model (Nowe, W trakcie, Wygrane, Przegrane) does not map 1:1 to HubSpot's pipeline-specific dealstage values. HubSpot scopes dealstage pick-list values per pipeline, so each MiniCRM deal stage must be mapped to a specific HubSpot dealstage value within the target pipeline. We validate stage mapping during the sample migration and flag any stages with no HubSpot equivalent before the full run commits. Polish-language stage names in MiniCRM are preserved in HubSpot's custom property for audit continuity.
HubSpot marketing contact billing model has no MiniCRM equivalent

HubSpot's marketing contact flag is a billing construct that applies at Professional and Enterprise tiers — contacts who receive marketing emails trigger per-contact costs. MiniCRM has no equivalent distinction. We cannot automatically determine which MiniCRM contacts should be marketing-enabled in HubSpot. Your team must define the marketing contact policy post-migration; we preserve a reference field indicating which contacts had email activity in MiniCRM to inform that decision.
MiniCRM N:N contact-to-company associations require HubSpot junction management

MiniCRM allows multiple companies per contact without a formal linking table UI. HubSpot uses a primary company lookup (Contact → Company) plus a Company Contact Associations table for secondary links. We migrate the primary company by most-recent-activity rule and surface secondary associations in the Company Contact Associations table. This requires your HubSpot admin to enable and review the Associations API for contacts with multiple company links.
MiniCRM automations do not migrate — HubSpot Workflows must be rebuilt

MiniCRM's automation triggers (status-change emails, task assignments, deadline notifications) have no equivalent in HubSpot's workflow model. HubSpot Workflows use enrollment criteria, branching logic, and action sets that MiniCRM's trigger-action model does not support. We export your MiniCRM automation definitions as a reference document. Your HubSpot admin must rebuild automations in HubSpot's workflow builder; we can provide a rebuild guide mapping MiniCRM triggers to HubSpot enrollment triggers.
Polish-language field names and pick-list values require encoding normalization

MiniCRM data commonly contains Polish diacritics (ą, ć, ę, ł, ń, ó, ś, ź, ż) in company names, industry values, and pick-list options. HubSpot's API handles UTF-8 encoding, but downstream tools (reporting, email merge) may not. We normalize encoding during transformation and flag any pick-list values with diacritics that need value mapping to HubSpot's standard pick-list options.

Migration approach

Six steps for a successful MiniCRM to HubSpot data migration

Audit MiniCRM data model and export structure

FlitStack reads your MiniCRM data via API export or CSV download, cataloging all objects (contacts, companies, deals, tasks, notes), custom fields, pick-list values, and owner records. We document the full schema before writing any transformation logic. This step identifies duplicate records, missing foreign keys, and encoding issues that affect migration scope.
Create HubSpot custom properties and pipeline configuration

Before data moves, your HubSpot admin (or our team) creates the custom properties and pipeline configuration needed for MiniCRM fields that have no HubSpot standard equivalent. This includes custom properties for MiniCRM ID tracking, custom multi-picklist for tags, and deal pipeline stages mapped from MiniCRM's status values. We deliver a HubSpot setup checklist so the destination schema is ready before validation runs.
Resolve owners and validate association rules

MiniCRM owner IDs are matched to HubSpot users by email. Unmatched owners are flagged before migration — your team either invites them to HubSpot or assigns their records to a fallback owner. We also validate MiniCRM's N:N contact-company associations and surface the primary company per contact using your specified rule (most-recently-modified or your defined priority). No record lands in HubSpot without a resolved owner.
Run sample migration with field-level diff

A representative slice migrates first — typically 100–500 records spanning contacts, companies, deals, tasks, and notes. We generate a field-level diff between source MiniCRM records and destination HubSpot records so you can verify stage mapping, owner resolution, and custom property population before the full run commits. Polish-language values and diacritics are validated in this step.
Execute full migration with delta-pickup window

The full migration runs against HubSpot via API, sequencing objects correctly (Companies → Contacts → Deals → Tasks → Engagements) to preserve foreign-key relationships. A delta-pickup window (typically 24–48 hours) captures any records modified in MiniCRM during cutover. Audit log captures every operation; one-click rollback is available if reconciliation identifies data discrepancies at go-live.

Platform deep dives

Context on both ends of the pair

MiniCRM

Source

Strengths

Card-based record model is easy for small teams to understand and use immediately.
Monthly subscription tiers scaled to micro and small business budgets, with no upfront installation cost.
Built-in automation triggers and actions cover common follow-up sequences without third-party tools.
Active Polish-language support community and documented features tailored to local SME workflows.
Responsive browser-based UI accessible on desktop and mobile without requiring desktop software.

Weaknesses

API documentation is sparse — no public rate limit spec, no bulk export endpoint clearly documented, limiting automated migration options.
Pricing transparency is a known friction point — customers report difficulty understanding what features map to which subscription tier.
Small product team and regional focus mean fewer third-party integrations compared to global CRM platforms.
Automation rules cannot be exported and must be manually rebuilt in the destination system.
Recent acquisition by group.one introduces potential for product instability, API changes, or shifting support terms.

HubSpot

Destination

Strengths

Genuinely useful free CRM tier with no seat limit on contact records.
All-in-one sales engagement layer (sequences, email tracking, calling, dialer) embedded natively in the CRM, eliminating a separate integration.
Intuitive interface and fast onboarding for individual reps, per G2 and Capterra reviews.
Workflow automation triggers across contacts, deals, and tickets with a visual builder.
API coverage for all standard objects including custom objects at Enterprise tier.

Weaknesses

Pricing model is contact-based at the marketing layer — importing all records as marketing contacts can multiply the monthly bill by 4×.
Feature tier cliffs are frequent surprises: sequences, calling, advanced reporting, and quoting are all gated, often requiring plan upgrades mid-implementation.
Mandatory onboarding fees at Professional ($1,500) and Enterprise ($3,500) are not prominently disclosed on the pricing page.
API rate limits are restrictive for bulk migration — burst limits of 100-200 req/10sec and search endpoint limits of 4 req/sec require careful job queuing.
Custom objects, additional pipelines, and advanced forecasting are Enterprise-only, making cost projections difficult for growing teams.
