How long does a Smarketing Cloud to HubSpot migration take?

Most Smarketing Cloud to HubSpot migrations complete in 48–72 hours for under 25,000 records. Larger datasets with 200,000+ records or heavy custom property usage extend to 5–8 days. The longest planning step is auditing Smarketing Cloud custom fields and creating matching HubSpot properties — this runs before the migration clock starts. During the audit, we pull all contacts, companies, deals, and custom field definitions via Smarketing Cloud's REST API. After mapping and transformation, we import via HubSpot's Bulk API. A 24–48 hour delta pickup captures any in‑flight records created during the final cutover, ensuring HubSpot reflects the latest state when you go live.

Will my Smarketing Cloud workflows and automations migrate to HubSpot?

No. FlitStack AI migrates data and schema only — workflows, automation rules, and sequences stored in Smarketing Cloud do not transfer to HubSpot. They must be rebuilt in HubSpot's workflow engine. We export your Smarketing Cloud workflow definitions as a structured rebuild reference for your HubSpot admin to use as a design document for the new automation logic, including triggers, conditions, and time‑delay actions.

What happens to Smarketing Cloud contact lifecycle data in HubSpot?

Smarketing Cloud contacts without an explicit lifecycle stage land in HubSpot as 'lead' by default — the conservative starting point for HubSpot's lifecycle model. If Smarketing Cloud tracks lifecycle indirectly (e.g., via deal stage progression), we use that history to assign a more accurate HubSpot lifecycle stage during migration. Contacts that have associated closed-won deals receive the 'customer' lifecycle stage.

Can I migrate Smarketing Cloud custom fields to HubSpot custom properties?

Yes. Every Smarketing Cloud custom field maps to a HubSpot custom property with a matching data type. We create the properties in HubSpot before import and map picklist values value-by-value so no data is lost or truncated. Text, number, date, and boolean types migrate directly; multi-select picklists require HubSpot's multi-checkbox property type. During the audit, we also capture any conditional formatting or validation rules present in Smarketing Cloud, then document them for your HubSpot admin to consider when configuring property settings.

What happens to Smarketing Cloud deal pipelines in HubSpot?

Smarketing Cloud deal pipelines map to HubSpot deal pipelines with stage names translated value-by-value. If Smarketing Cloud uses a single pipeline, we create one corresponding HubSpot pipeline. Probability values from Smarketing Cloud stages apply to HubSpot stages unless your team specifies different forecast probabilities — those are a HubSpot configuration decision made post-migration. We also preserve any custom stage labels such as 'Proposal Sent' or 'Negotiation' as HubSpot stage names, ensuring your sales process terminology transfers without manual renaming.

Does the migration affect my Smarketing Cloud account during cutover?

No. FlitStack AI uses scoped read access on Smarketing Cloud — your team continues working in Smarketing Cloud throughout the migration. A delta-pickup window of 24–48 hours captures records created or modified during the cutover window so HubSpot reflects Smarketing Cloud's final state at go-live. No records are deleted or modified in Smarketing Cloud. During this window, any new contacts, deals, or activity entries added by your sales team are automatically pulled into the final import, maintaining data continuity and eliminating the need for a second cutover.

Will migrated contacts be counted as HubSpot marketing contacts?

No. To avoid HubSpot marketing contact billing surprises, all migrated contacts are set to non-marketing status by default. Your team reviews contact consent records in Smarketing Cloud and selectively updates the HubSpot marketing contact flag per your email marketing consent policy. This is a post-migration administrative step, not an automated migration action. If Smarketing Cloud records include explicit email opt‑in flags or GDPR consent timestamps, we capture those values in a custom property so your team can apply them accurately when activating marketing contacts in HubSpot.

Smarketing Cloud to HubSpot Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

Smarketing Cloud operates a simplified CRM model centered on Contacts, Companies, Deals, and basic activity logging with standard fields for names, emails, phone numbers, and deal values. HubSpot uses a richer object graph that includes lifecycle stages, marketing contact flags, association labels, multiple deal pipelines, and a property system that supports both standard and custom fields. The migration carries everything Smarketing Cloud stores natively — contacts, companies, deals, tasks, notes, and custom fields — into HubSpot's CRM object model. The primary complexity is translating Smarketing Cloud's contact lifecycle model into HubSpot's lifecycle_stage property, mapping deal stages to HubSpot pipeline stages, and recreating any association labels as HubSpot custom properties. Automations, email templates, and workflow logic do not migrate and must be rebuilt in HubSpot. We access Smarketing Cloud via its REST API, export all records in structured JSON, transform field names and data types to match HubSpot's property conventions, and import via HubSpot's Bulk API or CRM API depending on volume. A sample migration with field-level diff validates the mapping before the full run commits.

Why teams make this switch

Two sides of the same decision

Leaving

Smarketing Cloud

What's pushing teams away

Teams outgrow the platform when data volumes increase — performance degrades during heavy campaign send periods and the infrastructure does not scale as cleanly as enterprise-grade alternatives.
Steep learning curve for non-technical users means ongoing training investment is required before teams become productive, especially for building complex automation workflows.
Hidden costs accumulate through add-on modules, per-contact pricing above plan limits, and implementation fees that are not disclosed in published pricing tiers.
Support responsiveness is inconsistent — some teams report delays when resolving configuration issues or API integration problems, particularly on lower-tier plans.
Limited third-party integrations compared to established platforms creates friction for teams using HubSpot, Salesforce, or ERP systems that require native connectors.

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 Smarketing Cloud objects map to HubSpot

Each row shows how a Smarketing Cloud 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.

Smarketing Cloud

Contact

maps to

HubSpot

Contact

1:1

Fully supported

Direct map. HubSpot Contact receives all Smarketing Cloud contact fields. If Smarketing Cloud records include a lifecycle stage value, it maps to the Lifecycle_Stage__c custom property we create in HubSpot before import. We also preserve original create dates, owner IDs, and source system IDs as separate custom properties for traceability and future delta imports.

Smarketing Cloud

Company

maps to

HubSpot

Company

1:1

Fully supported

Direct map. HubSpot Company (Account equivalent) receives company name, domain, industry, employee count, and annual revenue. Parent-child company hierarchies in Smarketing Cloud translate to HubSpot's parent company association. We also map the original company creation timestamp and any custom fields to ensure the full profile is available in HubSpot for segmentation and reporting.

Smarketing Cloud

Deal

maps to

HubSpot

Deal

1:1

Fully supported

Direct map. Smarketing Cloud deals migrate as HubSpot Deals with deal name, amount, close date, and owner preserved. The pipeline and stage names map to HubSpot pipeline and stage properties value-by-value. We retain the original deal creation date and any custom properties for reporting continuity.

Smarketing Cloud

Task / Activity

maps to

HubSpot

Engagement Timeline (Task / Note)

1:1

Fully supported

Smarketing Cloud tasks and notes map to HubSpot engagements. Call logs, emails, and meeting records become HubSpot engagements with original timestamps and owner emails preserved for audit continuity. We also map any custom activity types to HubSpot's custom activity schema, ensuring that specialized sales interactions are visible in the timeline.

Smarketing Cloud

User / Owner

maps to

HubSpot

User

1:1

Fully supported

Owner resolution by email match against HubSpot users. Unmatched owners are flagged before migration — your team either creates HubSpot users first or assigns records to a designated fallback owner. The resolution report also shows the count of records per owner, helping you plan user provisioning and role assignments before go‑live.

Smarketing Cloud

Custom Field (Contact)

maps to

HubSpot

Custom Property (Contact)

1:1

Fully supported

Smarketing Cloud custom fields on contacts become HubSpot custom properties. We create each property in HubSpot with matching data type (text, number, date, picklist) before the import run. If a custom field contains multi-select values, we map it to HubSpot's multi-checkbox property type to preserve all selections without concatenation.

Smarketing Cloud

Custom Field (Company)

maps to

HubSpot

Custom Property (Company)

1:1

Fully supported

Smarketing Cloud custom fields on companies map to HubSpot Company custom properties. Same type-aware creation process applies — picklist values map value-by-value to HubSpot picklist options. We also preserve any numeric or date custom fields with original precision, and store the source field name in a reference property for future troubleshooting.

Smarketing Cloud

Custom Field (Deal)

maps to

HubSpot

Custom Property (Deal)

1:1

Fully supported

Smarketing Cloud custom fields on deals become HubSpot Deal custom properties. Data type conversion handles date formats, currency fields, and multi-select picklists to match HubSpot's property type constraints. We retain the original deal currency symbol and convert amounts to the default HubSpot currency using the exchange rate at migration time.

Smarketing Cloud

Attachment / File

maps to

HubSpot

Files (HubSpot)

1:1

Fully supported

Smarketing Cloud file attachments re-upload to HubSpot Files and link to the parent contact, company, or deal record. File size limits apply — HubSpot caps individual files at 25MB. If a file exceeds the limit, we split it into smaller chunks or link to an external reference in the CRM notes.

Smarketing Cloud

Association Label

maps to

HubSpot

Custom Junction Property / Association Label

1:1

Fully supported

If Smarketing Cloud uses labeled associations between contacts and deals (e.g., Decision Maker, Influencer), we preserve those labels as HubSpot custom properties on the deal-contact association. HubSpot's native association labeling scope is limited, so a custom property preserves the semantic meaning.

Smarketing Cloud	HubSpot	Compatibility
Contact	Contact1:1	Fully supported

Pair-specific challenges

HubSpot lifecycle stage requires a custom property when Smarketing Cloud has no equivalent

Smarketing Cloud does not enforce a lifecycle stage property on contacts — lifecycle is often inferred from deal activity or not tracked at all. HubSpot bills on marketing contacts and uses lifecycle_stage for lead routing, so contacts without an explicit stage value need a default assignment during migration. We set unmapped contacts to 'lead' as the default HubSpot lifecycle stage, which is the safest starting point for most teams but may need adjustment based on your sales process definition.
Association labels between contacts and deals need HubSpot custom property preservation

Smarketing Cloud allows labeled associations between contacts and deals (e.g., Decision Maker, Influencer, Champion). HubSpot's native association model supports basic role labels but does not expose arbitrary custom labels through the standard CRM UI. We preserve Smarketing Cloud association labels as a custom deal property (Association_Labels__c) that stores the label value as a comma-separated list. Your HubSpot admin can convert these to HubSpot association labels or keep them as a reference property.
Smarketing Cloud custom fields become HubSpot custom properties — type mapping required

Smarketing Cloud stores custom fields with implicit types (text treated as string, numbers as numeric). HubSpot requires explicit property types — picklist, date, number, text, boolean. We audit Smarketing Cloud custom fields before migration and create matching HubSpot properties with the correct type. Any picklist values in Smarketing Cloud map to HubSpot picklist options value-by-value to avoid silent data truncation on import. For numeric fields we enforce integer or float precision according to Smarketing Cloud metadata, and for date fields we standardize to ISO 8601 so HubSpot's date picker interprets them correctly. Multi-select picklists become HubSpot multi-checkbox properties, preserving all selected values without concatenation.
Single Smarketing Cloud pipeline maps to one HubSpot pipeline but stage names differ

Smarketing Cloud pipelines typically use generic stage names (e.g., New, Qualified, Won, Lost). HubSpot pipelines use stage names you define, and the stage probability values drive forecasting. We map Smarketing Cloud stages to HubSpot stages value-by-value and apply HubSpot's standard probability percentages per stage unless your Smarketing Cloud data includes explicit probability values. Stage probability reconfiguration is a configuration step your team validates before go-live. If Smarketing Cloud stage names differ from your desired HubSpot terminology, we retain the original names in a temporary custom property and provide a rename script your admin can run after go‑live.
Marketing contact billing flag has no direct HubSpot equivalent

Smarketing Cloud does not separate contacts into marketing and sales billing categories. HubSpot charges based on marketing contacts, which are contacts opted into marketing emails. If your HubSpot portal will use HubSpot's marketing features, we flag all migrated contacts as non-marketing by default (the conservative setting) so your team can selectively update the marketing contact status in HubSpot based on your email consent records. This prevents unintended billing surprises at migration.

Migration approach

Six steps for a successful Smarketing Cloud to HubSpot data migration

Audit Smarketing Cloud data model and export via API

FlitStack AI connects to Smarketing Cloud via its REST API using scoped read access. We export all Contacts, Companies, Deals, Activities, and Custom Fields with field names, data types, and picklist values. This audit identifies orphaned records, duplicate email addresses, and custom field types that need HubSpot-side property creation before import. During export we capture any custom relationship labels, company hierarchies, and attachment references so they can be recreated in HubSpot. The export is structured JSON, preserving original timestamps and owner IDs for accurate record recreation.
Create HubSpot custom properties and pipeline configuration

Before data moves, we create all required HubSpot custom properties for contacts, companies, and deals based on the Smarketing Cloud audit. If Smarketing Cloud uses multiple pipelines or named stages, we configure matching HubSpot pipelines and stage names. This step runs in parallel with your team validating the HubSpot portal setup so schema is ready before validation. We also set up any required picklist options, define validation rules, and configure default values for new properties. If your Smarketing Cloud data includes deal probability percentages, we apply those to the corresponding HubSpot pipeline stages during setup.
Resolve Smarketing Cloud owners to HubSpot users by email

Owner records in Smarketing Cloud map to HubSpot users via email address matching. We generate a pre-migration owner report that lists matched users, unmatched owners, and the fallback assignment rule (typically a designated HubSpot admin). No record imports without a resolved HubSpot owner ID. If multiple Smarketing Cloud owners share the same email, we flag duplicates and resolve to a single HubSpot user to prevent split assignments. The report also includes a summary of owner coverage by record type so you can assess training needs before go‑live.
Run sample migration with field-level diff

A representative slice of 100–500 records migrates first — spanning contacts, companies, deals, and activities. We generate a field-level diff comparing source values against HubSpot values for every mapped field. You verify lifecycle stage defaults, association label preservation, and owner resolution before the full run commits. The diff report highlights any data type mismatches, missing picklist options, and truncated text fields, allowing your team to adjust HubSpot property settings before the full load. We also test association integrity by verifying contact‑company and deal‑contact links are preserved.
Execute full migration with delta-pickup window

The full dataset migrates to HubSpot. A delta-pickup window of 24–48 hours captures records created or modified in Smarketing Cloud during cutover so HubSpot reflects the final state at go-live. FlitStack AI logs every import operation. One-click rollback reverts the HubSpot portal to its pre-migration state if reconciliation fails. During the delta window, any new contacts, deals, or activity logs are automatically appended to the import set, ensuring no data is missed. The import log records each batch's record count, error details, and timestamp for auditability.
