How long does an Optimiser CRM to HubSpot migration take?

Most Optimiser-to-HubSpot migrations complete in 48–72 hours for under 50,000 records. Larger setups with 500,000+ records or extensive custom property configurations extend to 7–14 days. The longest planning step is lifecycle stage value mapping and custom property schema design — typically 1–2 weeks of preparation before data import begins. Actual data import typically takes 1–3 days depending on record volume, activity history depth, and the number of custom fields requiring transformation logic.

Will my Optimiser CRM workflows migrate to HubSpot?

No. Optimiser workflows and automation rules do not migrate because HubSpot's automation engine operates on a different execution model. FlitStack AI exports your Optimiser workflow definitions as a rebuild reference document, and your team recreates them in HubSpot's workflow builder. Automations are typically rebuilt for the most critical use cases first — lead routing, deal stage updates, and follow-up sequences.

What happens to Optimiser's lead status in HubSpot?

Optimiser's lead status values map to HubSpot's lifecycle_stage property on the Contact object. Standard values (Subscriber, Lead, MQL, SQL, Customer, Evangelist) migrate directly if they match HubSpot's default options. Custom lead status values require HubSpot-side option creation before migration — your team reviews and approves the value-mapping specification before the migration runs. Any Optimiser lead status values without a HubSpot equivalent are flagged for custom option creation or manual reassignment.

Can I migrate Optimiser custom objects to HubSpot custom objects?

Yes, Optimiser custom objects migrate to HubSpot custom objects on Enterprise plans. Custom object data, custom field values, and associations transfer to HubSpot. The HubSpot custom object schema must be pre-created in HubSpot (this is done programmatically as part of the migration). Custom object associations that use many-to-many relationships in Optimiser map to HubSpot association types. Your team approves the custom object mapping and schema configuration before migration runs.

What happens to Optimiser deal pipelines in HubSpot?

Each Optimiser deal pipeline becomes a HubSpot deal pipeline. Optimiser pipeline stage names and probability percentages are recreated in HubSpot as dealstage options with corresponding probability values. The migration plan maps each Optimiser pipeline to its HubSpot equivalent, and your team configures the pipeline stages in HubSpot before deal data imports. You can adjust stage names, probabilities, and pipeline layout in HubSpot after migration.

Will my Optimiser activity history (calls, emails, meetings) transfer to HubSpot?

Yes. Optimiser activity records — calls, emails, meetings, and notes — migrate as HubSpot engagements with their original timestamps, owners, and parent-record associations (contact or deal) preserved. Engagement associations link to the migrated HubSpot contacts and deals using the preserved source record IDs. Activity migration runs after the contact and deal import is validated. Engagement history continuity is maintained for reporting and historical context in HubSpot.

Does the migration affect my Optimiser CRM account during cutover?

No. FlitStack AI uses scoped read access on Optimiser CRM — your team continues working in Optimiser throughout the migration. A delta-pickup window (typically 24–48 hours after the main import) captures any records created or modified in Optimiser during the cutover, ensuring HubSpot reflects Optimiser's final state at go-live. Optimiser remains fully operational until your team confirms the HubSpot cutover is complete.

Optimiser CRM to HubSpot Migration — Field-Level Mapping & Rollback

Overview

What this migration involves

Optimiser CRM stores contacts, companies, and deals as separate object types with independent field schemas. HubSpot uses a unified Contact model with lifecycle_stage as the primary customer-progression property, Companies for account-level data, and Deals with pipeline-and-stage properties. The migration translates Optimiser contacts to HubSpot contacts, preserving Optimiser's custom field definitions as HubSpot custom properties where no native equivalent exists. Activity history (calls, emails, meetings, notes) migrates as HubSpot engagements with original timestamps and owner associations intact. Optimiser's workflow definitions, email templates, and automation rules do not transfer — those are documented in the migration plan for your team to rebuild using HubSpot's workflow builder. FlitStack AI runs the migration via HubSpot's API (and bulk import for large datasets) using scoped read access on Optimiser, so your team keeps working in Optimiser during the entire cutover window. All deal amounts, contact creation dates, and association links between records are preserved to ensure continuity in reporting and historical analysis within HubSpot after cutover.

Why teams make this switch

Two sides of the same decision

Leaving

Optimiser CRM

What's pushing teams away

Data import is repeatedly cited as a weak point in reviews — small businesses migrating from spreadsheets or another CRM hit friction during onboarding.
Outlook integration depth varies by reviewer; some report automated email-report syncing does not work as expected, forcing manual exports.
UI is described as 'could be slightly more user-friendly' — fine for daily use but not as polished as Pipedrive, HubSpot, or Zoho CRM at similar price points.
Bank-transfer-only billing complicates procurement for buyers outside the UK or those used to monthly card billing.
Small G2/Capterra review footprint and a UK-centric ecosystem mean buyers outside the UK have limited reference customers and partner availability.

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 Optimiser CRM objects map to HubSpot

Each row shows how a Optimiser 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.

Optimiser CRM

Contact

maps to

HubSpot

Contact

1:1

Fully supported

Optimiser Contact maps directly to HubSpot Contact. Standard fields (firstname, lastname, email, phone) migrate as HubSpot properties. The lifecycle stage concept from Optimiser's Lead object becomes HubSpot's lifecycle_stage property. Custom contact fields that lack HubSpot equivalents are preserved as HubSpot custom properties with their original data types.

Optimiser CRM

Company

maps to

HubSpot

Company

1:1

Fully supported

Optimiser Company maps 1:1 to HubSpot Company. Company name, domain, industry, employee count, and annual revenue map as HubSpot properties. Parent-company hierarchy preserved via HubSpot's parent company association. Custom company fields without HubSpot equivalents become custom properties on the Company object.

Optimiser CRM

Deal

maps to

HubSpot

Deal

1:1

Fully supported

Optimiser Deal maps to HubSpot Deal. Deal name, amount, close date, and stage migrate as HubSpot Deal properties. The Optimiser pipeline becomes HubSpot's pipeline property on the Deal. Optimiser deal stage names and probability percentages are recreated as HubSpot dealstage options.

Optimiser CRM

Lead

maps to

HubSpot

Contact

many:1

Fully supported

Optimiser Lead merges into HubSpot Contact with lifecycle_stage set based on Optimiser's lead status. MQL/SQL-style values from Optimiser map to HubSpot lifecycle_stage options. Original lead creation date preserved as a custom property. Custom lead fields become custom properties on the HubSpot Contact.

Optimiser CRM

Call / Email / Meeting / Note

maps to

HubSpot

Engagement (Activity)

1:1

Fully supported

Optimiser activity records (calls, emails, meetings, notes) become HubSpot engagements. Original timestamps, owners, and parent-record associations (contact or deal) preserved. Engagement type maps to HubSpot's engagement type property. Each engagement links back to its source Optimiser record via the preserved source_record_id.

Optimiser CRM

Custom Field (Contact)

maps to

HubSpot

Custom Property

1:1

Fully supported

Optimiser custom contact fields without HubSpot equivalents become HubSpot custom properties. Field type (text, number, date, picklist) determines HubSpot property type. Picklist values are recreated as HubSpot option labels. Multi-select picklists translate to HubSpot multi-checkbox properties with array-formatted values.

Optimiser CRM

Custom Field (Company)

maps to

HubSpot

Custom Property

1:1

Fully supported

Optimiser custom company fields become HubSpot custom properties on the Company object. Data type mapping applies: dates become date properties, numbers become number properties, text becomes text properties. Boolean fields map to HubSpot's checkbox property type with true/false values.

Optimiser CRM

Custom Field (Deal)

maps to

HubSpot

Custom Property

1:1

Fully supported

Optimiser custom deal fields become HubSpot custom properties on the Deal object. Multi-select picklists in Optimiser are translated to HubSpot's multi-checkbox or single-select property based on the source field configuration. Currency fields preserve the original currency code as part of the value format.

Optimiser CRM

Owner / User

maps to

HubSpot

HubSpot User

1:1

Fully supported

Optimiser users are matched to HubSpot users by email address. Unmatched owners are flagged before migration — teams either invite them to HubSpot first or assign their records to a fallback HubSpot user. Activity owners without HubSpot accounts are imported without an owner assignment after flagging.

Optimiser CRM

Optimiser Record ID

maps to

HubSpot

Source_Record_ID__c

1:1

Fully supported

The original Optimiser record ID is preserved as a custom string property on each migrated record. This enables delta-run de-duplication and traceability back to the source system. The property name follows HubSpot's standard naming convention for source tracking fields.

Optimiser CRM

Workflow / Automation

maps to

HubSpot

N/A

1:1

Fully supported

Optimiser workflows and automation rules do not migrate — HubSpot's automation engine has a different execution model. FlitStack exports Optimiser workflow definitions as a rebuild reference for HubSpot workflow builder. Your team reviews the exported definitions and rebuilds critical automations in HubSpot after migration.

Optimiser CRM

Report / Dashboard

maps to

HubSpot

N/A

1:1

Fully supported

Optimiser reports and dashboards are not migrated. The underlying data (deals, contacts, activities) transfers to HubSpot where equivalent reports can be built. Historical report configuration is documented for manual rebuild. The migration specification includes a reference list of Optimiser reports for rebuilding in HubSpot.

Pair-specific challenges

Lifecycle stage value mapping requires explicit configuration

Optimiser's lead status values do not automatically align with HubSpot's lifecycle_stage options. If Optimiser uses custom status labels (Lead Qualified, Proposal Sent, Contract Review), those values must be explicitly mapped to HubSpot lifecycle_stage options during migration planning. Values that do not have a corresponding HubSpot option will default to the closest matching label or require a custom HubSpot option to be created before migration runs. We deliver a value-mapping specification before migration executes so your team approves the mapping logic.
Multi-select picklist fields require value-splitting logic

Optimiser's multi-select fields (fields that allow multiple values per record, such as product categories or service offerings) map to HubSpot's multi-checkbox property type. If Optimiser stores multi-select values as a delimited string (with commas or semicolons separating values), the migration splits the string and transforms each value into HubSpot's array format for multi-checkbox properties. Teams using picklist-based multi-select fields in Optimiser should review which fields qualify and approve the transformation logic before the full import runs. The migration specification includes a complete list of identified multi-select fields.
Custom field schema must be pre-created in HubSpot

HubSpot requires custom properties to be created before data can populate them. Unlike Optimiser, where custom fields can be created during data import, HubSpot requires the property schema (name, type, options) to exist before the import step. FlitStack AI creates the property schema programmatically via HubSpot's API, but teams should review the custom property list and approve the field types and picklist options before the schema creation step runs. Any custom HubSpot options (for picklist properties) are also created during this schema step.
Association integrity depends on import order

HubSpot's association model requires companies to exist before contacts can associate to them, and contacts to exist before deals can associate to them. Optimiser's flat import model does not enforce this dependency. The migration sequences companies first, then contacts with their primary company associations resolved, then deals with their contact and company links established. Skipping this order creates orphaned associations or failed imports. The migration plan documents the import sequence and validates each step before proceeding to the next.
Activity engagement owners resolve by email match

Optimiser activity records store owner information by internal user ID. HubSpot engagements associate owners by HubSpot user ID, which requires an email-based lookup against HubSpot's user list. If an Optimiser activity owner does not have a corresponding HubSpot user account, the engagement is imported without an owner assignment. We flag unmatched owners before migration and recommend creating HubSpot user accounts for all active Optimiser users before the activity import step.

Migration approach

Six steps for a successful Optimiser CRM to HubSpot data migration

Audit Optimiser CRM data and schema

We extract a full data dump from Optimiser CRM: all contacts, companies, deals, activities, custom field definitions, and user accounts. We document the field types, picklist values, and any custom object schemas used. We also inventory workflows, automation rules, and email templates that require manual rebuild in HubSpot. This audit produces a migration specification that your team reviews and approves before migration begins.
Design HubSpot property schema and field mapping

We map each Optimiser field to its HubSpot equivalent, creating HubSpot custom properties for Optimiser-specific fields that have no native HubSpot counterpart. We configure the HubSpot property schema via HubSpot's API — including picklist options for lifecycle stages and deal stages — before data import begins. The field-mapping specification documents each field transformation, custom property creation, and value mapping. Your team reviews and approves the mapping before migration execution.
Import companies, then contacts, then deals in sequence

HubSpot requires companies to exist before contacts can associate to them, and contacts to exist before deals can associate to them. We import companies first, then contacts with their primary company associations resolved, then deals with their contact and company links established. Owner assignment resolves by email match to HubSpot users. Each batch is validated before the next step proceeds.
Migrate activity history as HubSpot engagements

Calls, emails, meetings, and notes from Optimiser are imported as HubSpot engagements with their original timestamps, owners, and parent-record associations preserved. Engagement associations link to the migrated HubSpot contacts and deals using the preserved source record IDs. Activity migration runs after the contact and deal import is validated. We import activities in chronological batches to maintain engagement timestamp accuracy.
Run delta-pickup and validate final record state

After the full migration completes, we capture any records created or modified in Optimiser during the cutover window (typically 24–48 hours) and apply those changes to HubSpot. We validate record counts, field-level accuracy on a representative sample, and association integrity before your team approves go-live. One-click rollback is available if reconciliation uncovers unexpected discrepancies. Final validation reports are shared for your records and audit trail.
