Agency Migration Guide
Nimble to HubSpot Migration
What actually transfers, what quietly does not, and what has to be rebuilt by hand.
We mapped Nimble against HubSpot feature by feature: 38 features, 2 synced objects, 6 documented traps and 27 items that have to be rebuilt. The whole map is on this page, ungated.
The PDF is the same reference, formatted to send to a client.

The Two Objects That Sync Natively
What the connector moves for you, and which way each one flows.
Contact (Person)
Two wayBecomes Contact
Default matching by email address. Social profile URLs from Nimble are not included in default field mappings.
Contact (Company)
Two wayBecomes Company
Default matching by company name or domain. Association mappings link contacts to their companies.
Six Things the Sync Does Not Tell You
Each one is documented, and each one has ended a migration in a bad week.
No Deal/opportunity Sync
The native HubSpot Data Sync integration does not sync Nimble Deals to HubSpot Deals. Deals must be migrated separately via CSV export/import or API.
Workaround: Export deals from Nimble as CSV (limited to editable fields only) and import into HubSpot. Alternatively, use Zapier or a third-party middleware tool.
Notes and Email History Cannot Be Exported From Nimble
Nimble does not allow exporting notes or email correspondence. The CSV export only contains data from editable fields on contact/deal records.
Workaround: Use Nimble API to extract notes and activities programmatically, then import as HubSpot engagement activities via API. Manual screenshot/archive for critical records.
Social Profile Data Does Not Sync Natively
Nimble's core value proposition is social CRM enrichment (LinkedIn, Twitter/X, Facebook profiles). These social profile URLs and social engagement data are not included in the HubSpot Data Sync default field mappings.
Workaround: Custom field mapping may capture social URLs if stored as custom fields in Nimble. Social enrichment must be recreated using HubSpot's social tools or third-party enrichment services.
Dropdown and Multi-select Fields May Only Sync One-way
HubSpot Data Sync has a known limitation where dropdown select, radio select, and checkbox property types cannot always sync bidirectionally. These may map as one-way text fields.
Workaround: Manually verify field type mappings after initial sync setup. Create custom text properties in HubSpot if needed.
Phone Number Sync Limited to Primary, Mobile, and Fax
Only the first phone number syncs to the HubSpot Phone Number property. Additional numbers sync only if labeled as Mobile or Fax in Nimble.
Workaround: Manually map additional phone numbers to custom HubSpot properties.
Tags Do Not Sync Natively
Nimble tags (used heavily for segmentation and categorization) are not automatically mapped to any HubSpot property in the Data Sync integration.
Workaround: Export contacts with tags from Nimble CSV and import into HubSpot using a custom multi-select property or HubSpot static lists. Alternatively, use Zapier to push tag data.
The 27 Items That Get Rebuilt by Hand
This is the list that separates a quote that holds from one that does not.
Data And Objects
Deals and Opportunities
Nimble's sales records, held outside the scope of any native connector.
HubSpot: Deals
Export by CSV or API and import as deals. Pipeline and stage have to exist in HubSpot before the import or every deal lands in the default stage.
Notes and Activity History
Free-text notes and logged activity attached to contacts and deals.
HubSpot: Notes and the activity timeline
Not available through the standard export, so this needs API extraction. Budget the API work explicitly rather than assuming a CSV covers it.
Email Correspondence History
Email threads logged against Nimble records.
HubSpot: Logged email on the timeline
Not exportable from Nimble. Where the mailbox is still connected, reconnecting it to HubSpot recovers recent threads, which is usually cheaper than extraction.
Tags and Segmentation
Tags used to group contacts outside the field structure.
HubSpot: Contact properties and lists
Decide per tag whether it is a property value or a list. Importing every tag as its own property is the usual mistake.
Social Profile Enrichment
The LinkedIn, X and Facebook profile data Nimble attaches to a contact automatically.
HubSpot: Contact properties, or an enrichment product
This is Nimble's signature feature and HubSpot does not reproduce it for free. If the client relies on it, price the replacement rather than assuming it comes across.
File Attachments
Documents attached to contact and deal records.
HubSpot: Attachments on records
Pulled through the API and re-associated after the records land, so it is a second pass rather than part of the main import.
Web Form Submissions
Historical submissions captured by Nimble's forms.
HubSpot: Form submissions on the timeline
Historical submissions arrive as data, not as timeline events. Agree whether the history matters before paying to move it.
Automation
Nimble Workflow Automations
Nimble's Kanban-style process boards that move records through defined stages.
HubSpot: Workflows, with pipelines for the board itself
A board is two things in HubSpot: a pipeline for the stages and workflows for the automation. Splitting it correctly is most of the work.
Email Sequences and Group Messaging
Outbound sequences and one-to-many sends from Nimble.
HubSpot: Sequences and marketing email
Sales sequences and marketing sends are separate tools in HubSpot. Decide which each Nimble campaign really was before rebuilding it.
Task Automation Rules
Rules creating tasks when a record changes.
HubSpot: Workflow task actions
Rebuild the trigger, not just the task. Task due-date offsets are the detail that usually gets lost.
Pipeline Stage Automation Triggers
Actions fired when a deal changes stage.
HubSpot: Deal stage workflow enrolment
Stages must be created before the workflows, or the enrolment criteria have nothing to point at.
Reporting
Deal and Revenue Reports
Revenue and forecast reporting over the deal pipeline.
HubSpot: Deal reports and forecasting
Depends on deal amount, close date and stage arriving clean. Fix the import before rebuilding the report.
Pipeline Conversion Analytics
Stage-to-stage conversion reporting.
HubSpot: Deal funnel reports
Conversion reporting needs stage history, which the import does not carry. Expect it to build up from cutover rather than backfill.
Activity and Engagement Reports
Reporting on calls, emails and meetings logged by the team.
HubSpot: Activity reports
Restarts at migration unless activity history is extracted, which is the expensive item above.
Sales Rep Performance Dashboards
Per-owner dashboards used to track the team.
HubSpot: Dashboards and custom reports
Owner has to map to a real HubSpot user on import or every report attributes to nobody.
Sales And Marketing Config
Deal Pipelines and Custom Stages
Nimble's sales pipelines and the stages within them.
HubSpot: Deal pipelines and stages
Quick to build and needs doing first, because deals, workflows and reports all depend on it.
Custom Fields
Custom fields on contacts, companies and deals.
HubSpot: Custom properties
Map field type as well as name. A Nimble text field holding dates has to become a real date property or nothing downstream can filter on it.
Email Templates and Saved Messages
Reusable message templates used by the sales team.
HubSpot: Email templates and snippets
Rebuilt by hand. Personalisation tokens have different names and will not carry across.
Web and Lead Capture Forms
Forms feeding contacts into Nimble.
HubSpot: Forms
Swap every website embed at cutover or leads keep arriving in the old system.
Saved Searches and Segmentation Views
Saved filters the team works from day to day.
HubSpot: Saved views and active lists
Cheap to rebuild and worth doing early: it is what the team notices missing on day one.
Users And Permissions
User Accounts and Roles
Logins and the permission level attached to each.
HubSpot: Users and permission sets
Created fresh, and needed before the import so record ownership can resolve.
Team Assignments
Which users belong to which team.
HubSpot: Teams
Map the intent rather than the structure. A literal copy usually over-restricts.
Record Ownership and Visibility Rules
Who owns a record and who else can see it.
HubSpot: Record ownership and access settings
HubSpot partitions visibility differently. Confirm what the client actually needs hidden before reproducing old restrictions.
Integrations
Connected Social Accounts
The LinkedIn, X and Facebook connections behind Nimble's social features.
HubSpot: Social publishing and monitoring
HubSpot's social tools do publishing and monitoring, not per-contact profile enrichment. The two are not the same job.
Calendar Sync
Google Workspace or Microsoft 365 calendar connection.
HubSpot: Calendar integration and the meetings tool
Reconnected per user, not once for the account. Missing a user means their meetings stop logging silently.
Third-party App Connections
Native connectors and Zapier automations joining Nimble to other tools.
HubSpot: App Marketplace integrations and updated Zapier scenarios
Zapier scenarios need editing on both sides, since the trigger and the field names both change.
Email Provider Connection
The mailbox connection that logs conversations to records.
HubSpot: Connected inbox
Per user again. Connect before cutover so conversation logging is continuous rather than gapped.

Effort Estimator
How Big Is This Migration?
A handful of questions, no email required. The ranges come from the research above: every feature we mapped carries an effort figure, and this adds up the ones that apply to you.
Estimated Effort
Answer a couple of questions and an hours range appears here.
Built from our research on 38 Nimble features. It is a range, not a quote.
A planning range, not a quote. It is delivery effort only, with no project management line and no agency markup, so add your own. What moves it most in practice is data quality.
What Goes Wrong Most Often
The failures that show up again and again, in roughly the order they bite.
Nimble's CSV Export Does NOT Include Notes, Emails, or Activity History
this is a significant data loss risk if not addressed via API
Social Profile Enrichment (Nimble's Key Differentiator) Does Not Transfer
clients accustomed to social CRM features may need HubSpot Social tools or Clearbit/ZoomInfo
Tags Are Heavily Used in Nimble for Segmentation and HubSpot Has No Tag Object; Plan Tag-to-list or Tag-to-property Mapping Carefully, Because the Segmentation Maps Cleanly but Tag-triggered Automation Does Not

Questions
Nimble To HubSpot, Answered
Yes. Data sync, two way, covering 2 objects. What it does not do is rebuild configuration: that is the 27 items below.
Typically 2-4 weeks. Complexity is driven by automation and reporting depth, not by record count: the connector moves records, so a large database is not by itself a long project.
Of 38 features we mapped, 28 (74%) carry across directly and 10 (26%) map partially, meaning something is lost or reshaped. 0 have no HubSpot equivalent at any tier.
27 items have to be rebuilt by hand, and 6 documented limitations are not surfaced by the connector at all. The full list of both is on this page.
HubSpot Free (basic sync); Data Hub Starter+ for custom field mappings
Only in one direction. The sync is not bidirectional here, so a parallel period means picking a system of record and accepting drift in the other.
