Overview
Nimble CRM organizes all contact data in a flat, relationship-first object model where contacts, companies, and deals live in a simple properties bag. HubSpot separates contacts from companies with explicit lookup relationships, uses a lifecycle_stage property on contacts to track lead-to-customer progression, and supports multiple deal pipelines with configurable stages per pipeline. The migration carries contacts, companies, deals, activities, and custom fields from Nimble into HubSpot's object graph — creating HubSpot custom properties for Nimble fields that have no direct equivalent, mapping Nimble's deal stages to HubSpot pipeline stages, and resolving Nimble owner emails to HubSpot user accounts. HubSpot's association labels and Nimble's contact tags require manual reconstruction after migration. We do not migrate workflows, automations, email templates, social enrichment data, or file attachments — those are rebuilt post-migration using HubSpot's native tools. During the migration, FlitStack AI validates field-level mappings against HubSpot's property schema, creating custom properties for any Nimble field that lacks a direct counterpart. Owner resolution matches Nimble user emails to HubSpot user IDs, with unresolved owners flagged for manual assignment. The delta-pickup window captures changes made in Nimble during the cutover, ensuring minimal data loss.
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.

Object mapping
Each row shows how a Nimble CRM 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.
Nimble CRM
Contact (People)
HubSpot
Contact
1:1Nimble contacts map directly to HubSpot contacts. HubSpot stores contact properties in a flat properties bag (properties.firstname, properties.email). We map every Nimble standard field to its HubSpot equivalent property name. Nimble contacts without a company association land in HubSpot as contacts with no primary company.
Nimble CRM
Contact (people record)
HubSpot
Lead
1:1Nimble does not separate leads from contacts — all contacts live in one object. HubSpot uses lifecycle_stage to distinguish early-stage contacts from customers. We preserve the full Nimble contact record in HubSpot contacts and populate lifecycle_stage based on the contact's group or tag membership, defaulting to 'lead' where no segment signal exists.
Nimble CRM
Company
HubSpot
Company
1:1Nimble companies map 1:1 to HubSpot companies. Company properties (name, domain, industry, phone, address) map to HubSpot company properties with identical names or close equivalents. Nimble parent-child company hierarchies map to HubSpot's parent company lookup. Nimble's custom company fields, such as industry classification or employee count, map to HubSpot company properties with matching names. If Nimble uses pick-list fields, the values are created as HubSpot pick-list options during property setup.
Nimble CRM
Contact-Company association (N:N)
HubSpot
Contact-Company primary + secondary
1:1Nimble allows each contact to be associated with multiple companies simultaneously. HubSpot contacts have one primary company (via the hubspot_owner_id or company association field) plus optional secondary associations. We migrate the most recently modified company as primary and surface the rest as secondary HubSpot contact-company relationships.
Nimble CRM
Deal
HubSpot
Deal
1:1Nimble deals map directly to HubSpot deals. Each Nimble deal retains its name, amount, stage, close date, and owner. Nimble's single-pipeline or multi-pipeline configuration maps to HubSpot deal pipelines — each Nimble pipeline becomes a HubSpot pipeline with its own stage labels and probability weights.
Nimble CRM
Deal Stage
HubSpot
Deal Stage (per pipeline)
1:1Nimble deal stages map to HubSpot deal stages by value. Each Nimble pipeline maps to a corresponding HubSpot pipeline, and the stage names within each pipeline map one-by-one. Stage probability values are reapplied based on HubSpot's stage configuration. Closed-won and closed-lost statuses align across platforms.
Nimble CRM
Activity: Logged Call
HubSpot
Engagement (Call)
1:1Nimble logged calls migrate to HubSpot engagements with type=Call. The call subject, body, duration, direction (inbound/outbound), and timestamp are preserved. Call owner resolves by email match to HubSpot user. Call is linked to the associated contact via HubSpot's engagement association.
Nimble CRM
Activity: Email
HubSpot
Engagement (Email)
1:1Nimble logged emails migrate to HubSpot engagements with type=Email. The email subject, body, timestamp, and associated contacts are preserved. HubSpot creates engagement records linked to the contact. Note that email content and attachments may be subject to HubSpot's file size limits.
Nimble CRM
Activity: Meeting / Event
HubSpot
Engagement (Meeting)
1:1Nimble calendar events migrate to HubSpot engagements with type=Meeting. Title, body, start time, end time, location, and associated contacts are preserved. Owner resolves by email match to HubSpot user. HubSpot displays meetings on the contact's timeline under the Engagements section.
Nimble CRM
Activity: Note
HubSpot
Note
1:1Nimble notes map to HubSpot notes. The note body, create date, and associated contacts or companies are preserved. HubSpot notes display on the contact timeline and company timeline. If the Nimble note contains rich text, formatting is simplified to plain text or basic HTML consistent with HubSpot's note rendering.
Nimble CRM
Custom Data Fields
HubSpot
Custom Properties
1:1Nimble custom data fields on contacts, companies, and deals require HubSpot custom properties. We create HubSpot custom properties (type matches Nimble field type — text, number, date, dropdown) before import and map the data during migration. Custom property names are normalized to HubSpot's lowercase-with-hyphens naming convention.
Nimble CRM
Tag
HubSpot
HubSpot List / Tag
1:1Nimble tags do not have a direct HubSpot equivalent. Tags are migrated as HubSpot static list memberships — contacts with tag 'referral-partner' are added to the 'referral-partner' list. For Nimble tags that represent behavioral data, we recommend recreating equivalent HubSpot lists and populating them with HubSpot workflows post-migration.
Nimble CRM
Group / Smart List
HubSpot
HubSpot List
1:1Nimble groups and smart lists segment contacts by criteria. HubSpot lists serve a similar segmentation role. We map Nimble group names to HubSpot list names and add matching contacts. For Nimble smart lists with dynamic membership rules, we document the logic for manual recreation as HubSpot lists with filter conditions.
Nimble CRM
Owner
HubSpot
User
1:1Nimble owner records map to HubSpot users. Resolution happens by matching the Nimble owner email address against HubSpot user email addresses. Unmatched owners are flagged before migration — your team either invites them to HubSpot or reassigns their records to an existing HubSpot user before the migration runs.
Nimble CRM
Social Profile data
HubSpot
Contact social links (custom properties)
1:1Nimble enriches contact records with social profile data (LinkedIn, Twitter, Facebook URLs) automatically. This enriched social data is stored in Nimble's profile cache and is not exportable as part of a standard CSV export. We preserve the social profile URLs as HubSpot custom properties if they appear in the export — otherwise the social enrichment is not migrated and must be refreshed using HubSpot's enrichment tools post-migration.
Nimble CRM
Workflow / Automation
HubSpot
Workflow
1:1Nimble workflows (the Workflow tab with kanban-style process boards) do not migrate to HubSpot. HubSpot's workflow engine uses different trigger types, conditions, and actions. We export your Nimble workflow definitions as a reference document for your HubSpot admin to rebuild using HubSpot's workflow builder. Priority goes to workflows that affect deal stage progression and follow-up task creation.
Nimble CRM
Email Template
HubSpot
Email Template
1:1Nimble email templates and sequence templates do not migrate to HubSpot. HubSpot has its own template library with CRM-specific merge tags. We export your Nimble template content as a text reference document so your team can recreate them in HubSpot's template editor.
Nimble CRM
Attachment / File
HubSpot
HubSpot Files
1:1File attachments on Nimble contacts, companies, and deals are re-uploaded to HubSpot Files and associated with the target record. HubSpot's file size limit applies (default 25 MB per file). Files exceeding this limit are flagged for manual handling. We preserve the original filename and attach the file to the corresponding HubSpot record on migration.
Nimble CRM
Deal-Contact association
HubSpot
Deal-Contact association
1:1Nimble deal-contact associations map to HubSpot deal-contact associations. A Nimble deal linked to three contacts creates a HubSpot deal with the same three contacts associated via HubSpot's deal-contact association model. Association order is preserved where Nimble provides it. If a deal has no associated contacts in Nimble, the deal will be imported as a standalone HubSpot deal, and you can manually link contacts afterward.
Nimble CRM
Source System ID
HubSpot
HubSpot source ID (custom property)
1:1The original Nimble record ID is stored as a HubSpot custom property (nimble_record_id) on each record for traceability, delta-run de-duplication, and rollback identification. This property is invisible to end users but critical for migration audit and future sync operations. This ID property is indexed for fast lookups and can be used in HubSpot workflows to reference the original Nimble record.

Pair-specific challenges
Migration approach
Audit Nimble storage and export feasibility
Before any data is touched, FlitStack AI reviews your Nimble portal for storage usage, record counts per object, and active pipelines. We identify accounts near the 2 GB storage limit and flag them for cleanup. We also identify which Nimble fields are available in the standard export CSV versus fields that require manual export and map those gaps in the migration plan. This step produces a Nimble-specific pre-flight checklist before we trigger the first export.
Trigger Nimble export and receive CSV package
We initiate the Nimble contact, company, deal, and activity exports from within Nimble's UI. Nimble delivers the export files via email — FlitStack AI monitors for delivery and downloads the files. For large datasets, multiple export batches may be required. We parse the CSV files and validate record counts against Nimble's reported totals. Any discrepancies are flagged for re-export before proceeding to mapping.
Build HubSpot custom properties before import
We create HubSpot custom properties for every Nimble custom field and for properties that require preservation (original create date, source system ID). This includes custom date fields, number fields, and dropdown fields matching Nimble's field types. HubSpot custom property creation is done in the HubSpot portal before records are imported, ensuring all target fields exist at migration time. We use HubSpot's API to create properties in bulk and validate that they appear correctly in the HubSpot UI.
Migrate companies first, then contacts, then deals
HubSpot requires companies to exist before contacts can be associated with them via a company association. We sequence the migration: companies first, then contacts with their company associations, then deals with their contact associations. This foreign-key ordering prevents orphaned records. Nimble owner emails are resolved to HubSpot user IDs during this step — any unresolved owners are flagged and assigned to a fallback HubSpot user before records land.
Run sample migration with field-level diff
A representative slice — typically 100–500 records spanning contacts, companies, deals, and activities — migrates first. We generate a field-level diff comparing the Nimble source values against the HubSpot destination values for every mapped field. You review the diff to verify that lifecycle stage mapping, deal stage mapping, owner resolution, and company associations look correct before the full run commits. Adjustments to field mapping are made at this stage before the full dataset runs.
Execute full migration with delta-pickup window
The full dataset migrates to HubSpot using HubSpot's Bulk API for contacts and companies and the REST API for deals and activities. A delta-pickup window of 24–48 hours runs after the full migration, capturing any records created or modified in Nimble during the cutover. FlitStack AI generates a migration audit log listing every record migrated, its source Nimble ID, and its destination HubSpot ID. One-click rollback is available if reconciliation identifies discrepancies exceeding your defined tolerance threshold.
