Overview
AllClients stores contacts, companies, notes, and custom field data with a straightforward flat export model — contacts include standard fields (name, email, phone, address) plus any custom fields defined by the admin. Companies are separate records with a name-to-contact link. AllClients workflows run as multi-step sequences inside the platform and cannot be exported as portable definitions. HubSpot receives contact data via its Contacts API, company data via the Companies API, and maps AllClients custom fields to HubSpot custom properties created during setup. FlitStack AI extracts AllClients data through its documented CSV export and API endpoints, transforms field names and data types to match HubSpot property conventions (snake_case to camelCase, pick-list values normalized), and loads records via HubSpot's Contacts and Companies APIs. Workflows, email sequences, and automation logic require a separate rebuild phase — we provide an export of your AllClients workflow definitions as a reference blueprint for your HubSpot admin. Activity history (call logs, emails logged as notes) migrates as HubSpot engagement timeline entries. Owner resolution matches AllClients user email addresses against HubSpot user accounts by email lookup.
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 AllClients 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.
AllClients
Contact
HubSpot
Contact
1:1AllClients contact records map 1:1 to HubSpot contacts. Standard fields (name, email, phone, address) map to HubSpot's corresponding contact properties. Owner is resolved by email match to HubSpot user accounts; unmatched owners assign to a designated fallback owner. The contact's original create date is preserved as a custom property to maintain reporting continuity from the source system.
AllClients
Company
HubSpot
Company
1:1AllClients company records map directly to HubSpot companies. The company-to-contact association in AllClients translates to a HubSpot company-contact association. HubSpot's company properties (domain, industry, phone) receive AllClients company field values. Companies load into HubSpot before contacts to ensure association lookups resolve correctly during the contact migration phase.
AllClients
Contact Custom Fields
HubSpot
Contact Custom Properties
1:1AllClients custom fields on contacts require pre-created HubSpot contact properties with matching types (text, number, date, enumeration). We map each field by name, infer the HubSpot property type from the source data format, and create the property before the import runs.
AllClients
Company Custom Fields
HubSpot
Company Custom Properties
1:1Company-level custom fields in AllClients migrate to pre-created HubSpot company properties. HubSpot company properties are created with the same type and options as the source custom fields before the migration loads company records. If an AllClients company custom field uses a pick-list, all unique source values are extracted and created as enumeration options in HubSpot.
AllClients
Notes
HubSpot
Contact / Company Engagement Timeline (Notes)
1:1AllClients contact notes map to HubSpot contact engagement timeline entries (type: note). Original timestamps, note authors, and content are preserved in HubSpot's timeline. Notes attached to company records in AllClients migrate to the corresponding HubSpot company timeline, maintaining the full context of each note entry across the CRM transition.
AllClients
Workgroup / Group Actions
HubSpot
HubSpot List
1:1AllClients Workgroups (used for segmented exports and campaign targeting) map to HubSpot static Lists. We export each Workgroup membership and associate the contact records to the corresponding HubSpot list after the main contact load completes. If a Workgroup uses dynamic filter criteria, we document those rules for the admin to recreate as HubSpot Smart Lists.
AllClients
No native Deal object
HubSpot
Deal / Opportunity
1:1AllClients does not have a native deal or opportunity tracking object. If a customer has deal-like data stored in custom fields or as tagged contact records, we surface those fields for a HubSpot admin to create Deals or custom deal properties during the migration planning phase.
AllClients
Contact Owner / Assigned User
HubSpot
Contact Owner (HubSpot User)
1:1AllClients owner fields store a user name or ID per contact. FlitStack resolves each owner by email lookup against HubSpot user accounts. Contacts whose owner email has no HubSpot user match are flagged and assigned to a designated fallback owner before import.
AllClients
Tags / Labels
HubSpot
HubSpot Contact Properties (multi-checkbox or single-line text)
1:1AllClients tags on contacts (e.g., 'vip', 'referral', 'churned') migrate to a HubSpot contact property — typically a multi-checkbox or text-list property depending on how many unique tags exist. Tags with fewer than 100 unique values use a HubSpot enumeration property; higher-cardinality tags use a text field.
AllClients
Email / Communication History (logged in notes)
HubSpot
HubSpot Engagements (emails logged as timeline entries)
1:1AllClients email communications logged against contact records (stored as note entries with timestamps) migrate to HubSpot engagement timeline entries. Each logged email receives a timestamp, owner, and subject line derived from the note content. This preserves the full communication history within HubSpot's engagement timeline for each contact record.
AllClients
Task / Follow-up Reminders
HubSpot
HubSpot Tasks
1:1AllClients tasks and follow-up reminders attached to contacts migrate as HubSpot tasks with the same due date, owner, and description text. Completed vs. open status is preserved from the source record. Task ownership is resolved via the same email-matching logic used for contact owner resolution during the migration.
AllClients
Workflow Definitions
HubSpot
HubSpot Workflows / Sequences
1:1AllClients workflow definitions cannot be exported in a portable format. We export workflow step descriptions and trigger conditions as a reference document for a HubSpot admin to rebuild. No workflow logic moves automatically; the automation layer requires a separate rebuild project.

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.
AllClients gotchas
Contact count limits enforced as hard caps per tier
Notes export separately from main contact CSV
Workflows migrate as inactive templates only
API rate limits are undefined and enforced at vendor discretion
HubSpot gotchas
Marketing Contacts billing model is migration-critical
Feature tier gating is not visible until onboarding
Mandatory onboarding fees inflate year-one cost
HubSpot CSV importer cannot migrate engagements or attachments
Custom objects require Enterprise and a pre-existing schema
Pair-specific challenges
Migration approach
Audit AllClients data structure and export configurations
FlitStack connects to your AllClients account via the Data Migration export tool and API endpoints. We pull a full contact export, company export, and notes export. During this phase we identify all custom fields, tag sets, workgroup memberships, and owner assignments. We also capture the list of AllClients workflow definitions for the reference document. The audit produces a Data Migration Plan listing every object, field, and custom property that will be created in HubSpot before data moves.
Create HubSpot custom properties and list structures
Before any data loads, FlitStack creates all required HubSpot contact and company custom properties using the HubSpot Properties API. Property types (text, number, date, enumeration) are inferred from the AllClients export. Enumeration properties receive all unique pick-list values from AllClients. Simultaneously, we create HubSpot static Lists corresponding to each AllClients Workgroup. This step runs in a HubSpot sandbox or the live account (by agreement) and is validated before the migration load begins.
Resolve owners by email and validate foreign-key dependencies
AllClients owner names are matched against HubSpot user accounts by email address. FlitStack generates an Owner Resolution Report listing matched owners, unmatched owners, and the fallback owner assignment for each unmatched record. We also validate that all company records are ready before contact loads run, since contact-to-company links require the company to exist first. Any circular or orphaned references are flagged and resolved before the migration window opens.
Run a sample migration with field-level diff on 100–500 records
A representative sample of contacts, companies, and notes migrates into HubSpot first. FlitStack generates a field-level diff comparing source values (AllClients CSV) against destination values (HubSpot API response) for every field in the mapping plan. You review the diff to verify that custom property mapping, pick-list values, date formats, and owner resolution are correct. Sample migration runs typically complete within 2–4 hours and are a gate before the full migration proceeds.
Execute full migration with delta-pickup window and post-load validation
The full contact, company, and notes migration runs against the live HubSpot account using the sequence validated in the sample. A delta-pickup window of 24–48 hours is opened at the point of cutover — any contacts or companies created or modified in AllClients during the migration run are captured and applied to HubSpot before go-live. After the load completes, FlitStack runs a reconciliation report comparing record counts, field-population rates, and association completeness against the AllClients source data.
Deliver migration audit log, rollback plan, and workflow rebuild reference
FlitStack delivers a complete audit log of every record created, updated, or skipped during the migration, with source-system IDs and destination record IDs. If reconciliation reveals any discrepancy above the agreed tolerance, a one-click rollback reverts the HubSpot account to its pre-migration state. We also deliver the AllClients Workflow Reference Document listing every automation step for HubSpot rebuild, and a final Workgroup-to-List mapping sheet your team uses to finalize HubSpot list memberships.
