How long does a SalesNexus to HubSpot migration take?

Most SalesNexus-to-HubSpot migrations complete in 24–48 hours of clock time for under 25,000 records. Larger accounts with 100,000+ records or extensive custom-field inventories extend to 5–8 days. The field-ID-to-property-map audit takes 2–4 hours; the HubSpot schema setup (pipelines, custom properties) is the longest planning step if not handled pre-migration. The delta-pickup window adds another 24–48 hours on top of the full migration run.

Will my SalesNexus drip automations and Nexi AI rules migrate to HubSpot?

No. FlitStack AI migrates data and schema only — SalesNexus drip sequences, Nexi AI rules, and automation configurations are system-level logic, not CRM records, and have no import path into HubSpot. They must be rebuilt in HubSpot's Workflows and Sales Hub Sequences tools. We export your SalesNexus automation definitions as a JSON rebuild reference so your HubSpot admin has the full step-by-step logic when rebuilding.

What happens to SalesNexus contact notes and activity history in HubSpot?

Contact notes from SalesNexus migrate as HubSpot contact notes (plain text; rich-text formatting converts). Emails, calls, meetings, and tasks migrate as HubSpot engagement records with original timestamps preserved and displayed on the contact timeline. The engagement type (email, call, meeting) maps to HubSpot's engagement object type. Note that SalesNexus call logging depends on API availability — we verify this during the audit phase.

How does SalesNexus deal owner resolution work in HubSpot?

SalesNexus stores owner IDs as integers mapped to email addresses in user records. FlitStack resolves each owner ID to an email, then matches that email to a HubSpot user account by email. Records whose owners have no HubSpot user account land in a quarantine set — your admin creates the HubSpot account first, then FlitStack assigns the quarantined records. This prevents orphaned records with blank owner fields in HubSpot, which would break deal and task ownership visibility.

Does the migration affect my SalesNexus account during cutover?

No. FlitStack AI uses scoped read-access on SalesNexus — your team keeps working in SalesNexus throughout the migration. The scoped access allows data extraction but not modification of your source records. A delta-pickup window (24–48 hours) captures any records created or modified in SalesNexus during the cutover so HubSpot reflects your final state at go-live. Your SalesNexus account remains fully functional until you decide to cancel or downgrade.

How does HubSpot's marketing-contact billing model affect migrated contacts?

HubSpot charges based on marketing-contact count — contacts with a lifecycle_stage value of subscriber, lead, MQL, SQL, or opportunity are counted as marketing contacts regardless of plan tier. SalesNexus has no equivalent lifecycle field. FlitStack assigns a default lifecycle_stage (usually 'lead') to migrated contacts unless you specify a different rule. After migration, you can adjust lifecycle_stage values in HubSpot to manage your marketing-contact billing exposure. Contacts with no lifecycle_stage set are not counted as marketing contacts.

SalesNexus to HubSpot Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

SalesNexus stores contacts, companies, deals, and activity records with an API model that uses integer field IDs rather than named properties — a translation layer that HubSpot's property-based schema requires during migration. HubSpot's CRM object model centers on Contacts with lifecycle_stage as a billing flag, Companies with standard properties, and Deals organized into Pipelines with stage pick-list values. FlitStack AI extracts SalesNexus records via the API using field ID lookups, maps each to the corresponding HubSpot property by name, creates any custom properties required for non-standard fields, and preserves original create/update timestamps as custom datetime properties since HubSpot's native CreatedDate reflects import time. Automation sequences, drip campaigns, and Nexi AI rules do not migrate — those are rebuilt in HubSpot's Workflows and Sequences tools using a FlitStack export as the rebuild reference. The migration runs in scoped read-access mode so your SalesNexus account stays fully operational until cutover, with a delta-pickup window capturing any in-flight changes. Audit logging and one-click rollback protect the final reconciliation step.

Why teams make this switch

Two sides of the same decision

Leaving

SalesNexus

What's pushing teams away

The legacy version and the 2026 Nexi-powered version are distinct products requiring an explicit migration path, creating confusion and data duplication for long-time users.
Automation and enrichment limits on lower tiers are restrictive, pushing growing teams toward platforms like HubSpot or Salesforce with higher per-seat quotas.
The learning curve is steeper than expected; some actions lack intuitiveness and require consulting the training library, per multiple Capterra and G2 reviews.
Contact tier caps (1000 on free, 5000 on Starter) force mid-sized teams into paid upgrades or migration, with no transparent path to unlimited contacts.
Exporting drip automation sequences and Nexi AI configurations is not supported by the public API, requiring manual rebuilding in the destination system.

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 SalesNexus objects map to HubSpot

Each row shows how a SalesNexus 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.

SalesNexus

Contact

maps to

HubSpot

Contact

1:1

Fully supported

SalesNexus contacts map directly to HubSpot contacts. The translation step converts SalesNexus field ID integers to HubSpot property names (e.g., field 5 maps to firstname, field 6 to lastname). Email, phone, and address properties translate 1:1. Records without a primary company land as unassociated HubSpot contacts until company mapping resolves.

SalesNexus

Company

maps to

HubSpot

Company

1:1

Fully supported

SalesNexus companies map to HubSpot companies. Company name, domain, industry, employee count, and annual revenue translate by field ID to the matching HubSpot standard properties. Parent-child company hierarchies in SalesNexus map to HubSpot's parent company association via company ID lookup, preserving the organizational structure. Any unmapped custom company fields surface as custom properties requiring pre-creation in HubSpot before the migration run.

SalesNexus

Deal / Pipeline

maps to

HubSpot

Deal

1:1

Fully supported

SalesNexus deals map to HubSpot deals with pipeline and stage preserved. SalesNexus pipeline names become HubSpot pipeline names; deal stages map as value-mapped pick-list entries per pipeline. Amount, close date, deal owner, and custom deal fields carry over as HubSpot deal properties.

SalesNexus

Task

maps to

HubSpot

Task

1:1

Fully supported

SalesNexus tasks map to HubSpot tasks. Subject, due date, status, and owner email resolve to HubSpot task records. Completed task history, including completed date and notes, preserves as HubSpot task description and completion metadata. The task owner resolves by matching the SalesNexus owner email to a HubSpot user account. Unresolved owners flag records for quarantine until admin creates the matching HubSpot user. Recurring task patterns in SalesNexus map as individual task records in HubSpot.

SalesNexus

Email Activity

maps to

HubSpot

Email (Engagement)

1:1

Fully supported

SalesNexus logged emails map to HubSpot email engagements. Email subject, body, timestamp, and owner email preserve during migration. HubSpot's engagement timeline displays these under the associated contact or company record. The owner email resolves to a HubSpot user for attribution. Email attachments in SalesNexus require separate handling — FlitStack provides a file inventory during audit and guidance on attaching files to the appropriate HubSpot engagement records post-migration.

SalesNexus

Call Activity

maps to

HubSpot

Call (Engagement)

1:1

Fully supported

SalesNexus call logs (if available via API) map to HubSpot call engagements. Duration, call outcome, and notes attach to the contact record. Call recording links stored as a custom property on the engagement if SalesNexus exposes them. HubSpot's call engagement model captures call direction (inbound/outbound), disposition, and duration. If SalesNexus records call duration in minutes rather than seconds, FlitStack converts the value during the field mapping phase. Call recording URLs transfer as custom properties since HubSpot stores recordings separately.

SalesNexus

Meeting

maps to

HubSpot

Meeting (Engagement)

1:1

Fully supported

SalesNexus meeting records map to HubSpot meeting engagements. Start time, end time, title, attendees, and notes preserve during migration. HubSpot meetings display on the contact timeline and associate with the relevant company record. Meeting organizer and attendee emails resolve to HubSpot user and contact records respectively. If SalesNexus tracks meeting location or conference room details, these map to HubSpot's meeting location field or custom properties. FlitStack preserves the meeting title exactly as entered in SalesNexus.

SalesNexus

Custom Field (any object)

maps to

HubSpot

Custom Property

1:1

Fully supported

SalesNexus custom fields identified by non-standard field IDs translate to HubSpot custom properties. These must be pre-created in HubSpot with matching data types before migration. FlitStack generates a property-creation checklist from the SalesNexus field inventory during the audit phase. The checklist includes property name, display label, data type, and any picklist values. HubSpot's property API or manual property creation interface both satisfy the pre-creation requirement.

SalesNexus

Owner / User

maps to

HubSpot

HubSpot User

1:1

Fully supported

SalesNexus owner IDs (integers) resolve by email against SalesNexus user records, then matched by email to HubSpot user accounts. Unmatched owners are flagged in the migration report; their records are held in a quarantine set until your admin assigns a HubSpot user or creates the account in HubSpot first.

SalesNexus

Nexi AI Rules / Drip Sequences

maps to

HubSpot

Workflow / Sequence (rebuild reference)

1:1

Fully supported

SalesNexus Nexi AI rules and drip automation sequences are configuration data, not records, and do not migrate as data. FlitStack exports the rule definitions, sequence step order, and enrollment criteria as a JSON reference file your HubSpot admin uses to rebuild in HubSpot Workflows and Sales Hub Sequences.

Pair-specific challenges

SalesNexus field-ID model requires a translation layer that HubSpot's property-name model doesn't need

SalesNexus exposes fields via integer IDs in its API — the documentation shows field_id_lookup calls where field 5 is firstname, field 6 is lastname, etc. HubSpot's import model requires named property strings (firstname, lastname, email). FlitStack resolves the SalesNexus field ID inventory during the audit phase, builds a field-ID-to-HubSpot-property-name map, and uses that map for every record during migration. If a SalesNexus custom field has no clear HubSpot equivalent, it surfaces as a custom property to create before the migration run. This translation step is invisible to you but is the single most common source of migration failures when attempted without tooling.
SalesNexus drip automations and Nexi AI rules do not migrate as data

SalesNexus stores drip sequences, email automation rules, and Nexi AI configurations as system-level logic, not as CRM records. HubSpot has no equivalent import path for these — workflows and sequences are rebuilt as HubSpot-native automation objects. FlitStack exports your SalesNexus automation definitions (sequence step order, enrollment criteria, delay rules) as a JSON reference file. Your HubSpot admin uses this to rebuild in HubSpot Workflows and Sales Hub Sequences. Plan 1–3 days of admin time for this rebuild depending on automation complexity.
HubSpot's lifecycle_stage acts as a marketing-contact billing flag — migrated SalesNexus contacts need lifecycle assignment

SalesNexus has no native lifecycle_stage equivalent; contacts carry status or lead scores but not HubSpot's multi-stage lifecycle model. HubSpot charges based on marketing-contact count — contacts with lifecycle_stage set to subscriber, lead, MQL, SQL, or opportunity are counted as marketing contacts. FlitStack sets a default lifecycle_stage (usually 'lead') for migrated contacts unless your team specifies a different rule. You can post-migrate adjust lifecycle values in HubSpot to control billing exposure.
SalesNexus API rate limits apply during extraction — large datasets may require batching

SalesNexus API enforces per-account request limits (50 API calls on Free plan, higher on paid tiers). Large accounts with 50,000+ records may need chunked extraction runs. FlitStack's migration engine respects SalesNexus API quotas using exponential backoff, splitting large object queries into page-size batches to avoid hitting rate limit thresholds. This approach adds extraction time but prevents token revocation mid-migration and ensures all records are captured reliably. The audit phase estimates extraction time based on your record volume and plan tier, allowing you to plan for the additional window needed for large datasets.
Owner resolution by email is required before migration — orphaned records route to a quarantine set

HubSpot requires an owner_id on deals and tasks, and owner_id resolves by email match against HubSpot users. SalesNexus stores owner IDs as integers with email addresses in separate user records. FlitStack resolves the full owner map (integer ID → email → HubSpot user) before writing records. Users who exist in SalesNexus but not yet in HubSpot are flagged. If their HubSpot accounts are not created before migration, their records land in a quarantine set for post-migration manual assignment.

Migration approach

Six steps for a successful SalesNexus to HubSpot data migration

Audit SalesNexus field inventory and build the ID-to-property map

FlitStack runs a field inventory against your SalesNexus API, pulling the complete list of field IDs and their current values across a sample of records. This builds the translation map from SalesNexus field IDs (e.g., field 5, field 6) to HubSpot property names (firstname, lastname). Any custom fields that lack a HubSpot standard equivalent surface as candidates for custom property creation. The audit also captures pipeline names, stage values, and owner ID ranges so the full migration plan is scoped before any data moves.
Create HubSpot pipelines, custom properties, and user accounts

Before migration writes begin, your HubSpot admin (or FlitStack on your behalf) creates the pipeline structure matching your SalesNexus pipelines, sets up custom properties identified in the audit, and ensures all SalesNexus owner email addresses have corresponding HubSpot user accounts. This step prevents blocked writes from missing schema elements. FlitStack delivers a HubSpot setup checklist from the audit data so this can run in parallel with migration planning.
Run a sample migration with field-level diff on 100–500 records

A representative slice of SalesNexus records (contacts, companies, deals, and a few tasks) migrates to HubSpot using the ID-to-property map. FlitStack generates a field-level diff comparing source values against HubSpot imported values for every mapped field. You verify lifecycle_stage assignment, pipeline mapping, owner resolution, and timestamp preservation before committing to the full run. Adjustments to the field map and custom property list happen here.
Execute full migration with delta-pickup window

Full data extraction runs against SalesNexus in scoped read-access mode — your team continues working in SalesNexus throughout. A delta-pickup window (24–48 hours) captures any records created or modified during the cutover. All records write to HubSpot with original create timestamps preserved, owner IDs resolved, and pipeline/stage mapping applied. FlitStack's audit log records every operation and one-click rollback is available if reconciliation reveals unexpected data shape mismatches.
Reconcile and deliver the migration report

FlitStack runs a final reconciliation report comparing record counts, field completeness, and association integrity between SalesNexus and HubSpot. Quarantined records (unmatched owners, unmapped custom fields) appear in a separate tab with resolution instructions. You receive the Nexi AI automation export JSON for HubSpot rebuild, the field-ID-to-property map for documentation, and a post-migration checklist covering owner assignment, lifecycle_stage review, and pipeline stage probability tuning.
