Overview
Propeller CRM shut down on December 15, 2019, making this migration a data-retrieval-and-re-platforming project rather than a live-system switch. The primary challenge is that Propeller users must locate their own data exports or backups — FlitStack AI guides clients through that recovery step before any migration begins. Once data is in hand, the migration maps Propeller's three core objects — contacts, companies, and deals (with their associated pipeline stages) — into HubSpot's CRM objects. Propeller's custom tags and labels become HubSpot custom properties so segmentation data is not discarded. Email-tracking history, meeting records, and note bodies migrate as HubSpot engagements with original timestamps and owner attribution preserved. Because Propeller had no workflow engine, the migration carries no automation logic to rebuild. The HubSpot side requires custom property setup for any Propeller-specific fields before the import runs, and teams should configure their pipeline stages and deal properties in HubSpot before the migration commits so field mapping resolves cleanly on the first pass.
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.
Documents, uploads, and inline notes move with the record.

Object mapping
Each row shows how a Propeller 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.
Propeller CRM
Contact (person record)
HubSpot
Contact
1:1Propeller contacts map directly to HubSpot contacts. The primary company association migrates as the contact's primary company in HubSpot. Propeller's custom per-contact tags become a HubSpot custom multi-line-text or multi-select property so segmentation data is preserved for list-building. This ensures that all contact records retain their original categorization and can be segmented immediately after migration using HubSpot's native list tools.
Propeller CRM
Company (organization record)
HubSpot
Company
1:1Propeller company records map 1:1 to HubSpot companies. Domain is preserved as the company domain property for enrichment triggering. If a Propeller contact has no associated company, a placeholder HubSpot company is created so the contact has a valid primary association on import.
Propeller CRM
Deal (pipeline opportunity)
HubSpot
Deal
1:1Propeller deals map to HubSpot deals. Each deal carries its stage name, monetary value, close date, and owner. If Propeller used multiple pipeline views, the most-active pipeline becomes the primary HubSpot pipeline; others are recreated as additional named pipelines in HubSpot.
Propeller CRM
Pipeline Stage
HubSpot
Deal Stage (per pipeline)
1:1Propeller stage names map one-to-one to HubSpot deal stage names within each pipeline. Stage display order and probability are set in HubSpot's pipeline editor. If Propeller stage names conflict with HubSpot default stage names, custom stage names are created to preserve the exact source terminology.
Propeller CRM
Email (tracked email record)
HubSpot
Email (engagement)
1:1Propeller's Gmail-tracked email history migrates as HubSpot email engagements, associated to the corresponding contact and deal by email-address match and timestamp correlation. Open/click data from Propeller is stored as HubSpot custom properties on the engagement record since HubSpot tracks opens natively.
Propeller CRM
Note
HubSpot
Note (engagement)
1:1Propeller notes map to HubSpot notes with original create timestamps and owner attribution preserved. Rich-text formatting in Propeller notes is rendered as plain text in HubSpot notes; if the note contains structured data, it is stored in a custom property on the associated contact or deal.
Propeller CRM
Call log
HubSpot
Call (engagement)
1:1Propeller call records — including call duration, direction, and outcome — migrate as HubSpot call engagements. Call disposition (answered, voicemail, no answer) maps to HubSpot's call outcome property. Owner attribution and timestamp are preserved so activity history is complete in HubSpot.
Propeller CRM
Meeting / calendar event
HubSpot
Meeting (engagement)
1:1Propeller meeting records migrate as HubSpot meeting engagements with start/end time, associated contact, and owner preserved. If Propeller recorded a meeting outcome or follow-up task, that data is stored in HubSpot custom properties on the meeting record. This preserves the complete meeting history including outcomes and follow-up commitments, enabling teams to review past interactions and track accountability after migration.
Propeller CRM
Custom tag / label
HubSpot
Custom property (multi-select or text)
1:1Propeller's per-record tag system has no direct HubSpot equivalent — HubSpot uses lists, custom properties, and smart lists for segmentation. We create a HubSpot custom property for each unique Propeller tag and populate the tag values per record so list filters in HubSpot can reproduce the original segmentation.
Propeller CRM
User / owner
HubSpot
User
1:1Propeller owner names are matched to HubSpot users by email address. Unmatched owners are flagged and assigned to a fallback HubSpot user until the client provisions the correct HubSpot accounts. Owner assignment is resolved before deal migration so every opportunity lands with a valid HubSpot owner.

Pair-specific challenges
Migration approach
Locate and recover Propeller data export
FlitStack guides the client through locating their Propeller CRM data export — a CSV, JSON, or backup file created before the December 2019 shutdown. If no export is available, we assess Gmail-side recovery options and third-party email backup sources to reconstruct contacts, companies, deals, and activities. No migration planning begins until a source dataset is in hand and its record counts are confirmed against the client's expectations.
Audit data quality and design HubSpot schema
We audit the Propeller export for completeness: record counts, null fields, duplicate contacts, and missing owner assignments. Based on the audit, we design the HubSpot schema — create custom properties for Propeller tags and custom fields, configure pipeline stages matching the Propeller stage names, and set deal stage probabilities. The client approves the schema design before any data is imported.
Resolve owners and build import ordering plan
Propeller owner names are matched to HubSpot users by email. Owners without a matching HubSpot user are flagged with a fallback assignment so no deal or contact lands without an owner. We sequence the import: companies first, then contacts (linked to companies), then deals (linked to contacts and owners), then engagement records. This ordering preserves foreign-key integrity in HubSpot's object model.
Run sample migration and generate field-level diff
A representative sample — typically 100–500 records spanning contacts, companies, deals, and a mix of engagement types — is imported into a HubSpot sandbox or staging portal. We produce a field-level diff report comparing source values to destination field values so the client can verify tag mapping, owner resolution, company association, and stage naming before the full run commits. This validation step catches mapping errors early and ensures data integrity across all object types before production migration begins.
Execute full migration with manual delta supplementation
The full dataset imports into the production HubSpot portal. Because Propeller is offline, there is no live delta-pickup window — any records created after the export date must be identified by the client and imported via a supplemental import using the same field mapping. We provide a supplemental import template and instructions so the client can capture in-flight records without re-running the entire migration.
