Overview
CRUMP CRM runs on Microsoft Dynamics 365, storing contacts, companies, deals, and custom objects in a Dynamics-backed schema. HubSpot stores equivalent records in its own object graph with lifecycle_stage as the primary contact property, deal pipelines with stage-level probability, and an association model for contact-company links. The migration carries everything CRUMP holds natively — contacts, companies, deals, tasks, notes, files, custom objects, and owner assignments — into HubSpot's CRM. We handle the schema translation from Dynamics field types to HubSpot properties, consolidate CRUMP's multi-pipeline model into HubSpot's pipeline-and-stage framework, and resolve owner IDs by email match against HubSpot users. CRUMP workflows, project records, helpdesk tickets, and invoicing data do not have a HubSpot equivalent and must be rebuilt or archived separately. We deliver a sample migration with field-level diff before the full run commits, followed by a delta-pickup window that captures in-flight changes during cutover. Throughout the process, we maintain referential integrity across all object relationships to ensure data consistency.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a CRUMP 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.
CRUMP CRM
Contact
HubSpot
Contact
1:1CRUMP contacts map directly to HubSpot contacts via email-based deduplication to prevent duplicate records. Owner resolution runs by matching CRUMP owner email addresses against existing HubSpot user accounts. Records without a matching email are flagged in a pre-migration report for manual owner assignment before the full migration run executes. This prevents orphaned records and ensures proper assignment chains are maintained from day one in HubSpot.
CRUMP CRM
Company
HubSpot
Company
1:1CRUMP company records map to HubSpot company records using company name and domain as matching keys for deduplication. HubSpot supports N:N contact-to-company associations, allowing multiple contacts to link to the same organization. The primary company designation is set from CRUMP's primary-company relationship field. Secondary associations are created via HubSpot's association API after contact records land in the system.
CRUMP CRM
Deal
HubSpot
Deal
1:1CRUMP deals map to HubSpot deals with direct field mapping for amount, closedate, and dealname columns. CRUMP's multi-pipeline setup means each CRUMP deal carries a pipeline reference that must be translated to the corresponding HubSpot pipeline ID. HubSpot deal records are created within the pipeline that matches CRUMP's original pipeline assignment, preserving deal-to-pipeline relationships throughout the migration process.
CRUMP CRM
Pipeline
HubSpot
Pipeline (HubSpot)
1:manyCRUMP supports multiple independent pipelines, each with custom stage configurations and probability weightings. When CRUMP contains more than one pipeline, FlitStack offers two approaches: create multiple HubSpot pipelines mirroring CRUMP's existing structure, or consolidate all CRUMP pipeline stages into a single HubSpot pipeline with merged stage sets. Your team selects the consolidation strategy during the planning phase before migration runs to align with your reporting structure.
CRUMP CRM
Task / Activity
HubSpot
Engagement (calls, emails, meetings)
1:1CRUMP task records including calls, emails, and meetings logged against contacts or deals map to HubSpot engagements in the CRM. Original activity timestamps and owner assignments are preserved during the transformation to maintain accurate audit trails. HubSpot's engagement timeline displays these activities chronologically on each contact and deal record, giving teams full visibility into customer interaction history.
CRUMP CRM
Note
HubSpot
Note
1:1CRUMP notes map to HubSpot notes with rich-text formatting preserved where the source format remains compatible with HubSpot's note editor. CRUMP note attachments migrate as HubSpot file attachments linked to the same parent record, maintaining context for important customer discussions. This preserves the contextual information and attached reference materials that sales teams rely on for understanding deal history and customer interactions.
CRUMP CRM
Owner / User
HubSpot
Owner (HubSpot)
1:1CRUMP stores owners as Dynamics User GUIDs, which are 32-character identifiers that have no meaning in HubSpot's system. FlitStack resolves each Dynamics GUID to the corresponding owner's email address by querying the Dynamics user table, then matches that email against HubSpot user accounts. Unresolved owners are surfaced in a pre-migration report for your team to map manually before data transfer begins.
CRUMP CRM
Custom Entity (Dynamics-backed)
HubSpot
Custom Object or Custom Property
1:1CRUMP custom entities derive from Dynamics 365 custom tables. If your HubSpot account is on Enterprise tier, we create HubSpot custom objects and map the records directly. For Starter, Professional, or Team tiers, CRUMP custom entity fields migrate as custom properties on the standard Contact or Deal object — your admin chooses the target object during planning.
CRUMP CRM
File Attachment
HubSpot
File Attachment (HubSpot)
1:1CRUMP files attached to Dynamics annotations (email attachments, note attachments, entity file attachments) are downloaded from the Dynamics backing store and re-uploaded to HubSpot's file manager. Files over 25 MB are flagged; your team decides whether to split or exclude them from the migration.
CRUMP CRM
Pipeline Stage
HubSpot
Deal Stage (HubSpot)
1:1Each CRUMP pipeline stage name maps to a HubSpot deal stage name in the target pipeline. CRUMP stage probabilities are stored as a custom field in HubSpot since HubSpot's stage probability is tied to the stage pick-list, not a separate field. Stage-transition timestamps from CRUMP are preserved in a custom datetime field.
CRUMP CRM
Project / Helpdesk / Invoicing
HubSpot
No equivalent
1:1CRUMP bundles project management, helpdesk, and invoicing alongside CRM. These modules have no direct HubSpot equivalent. Project and helpdesk records must be exported separately and archived or rebuilt in dedicated tools. We can export these as structured CSVs for reference or re-import into HubSpot tickets (Service Hub) where applicable.
CRUMP CRM
Workflow / Automation (Dynamics)
HubSpot
No equivalent
1:1CRUMP automations run on the Dynamics layer (Power Automate flows, plugin steps, workflow definitions). These do not migrate. We export your workflow definitions as a JSON reference document for your HubSpot admin to rebuild using HubSpot workflows or Operations Hub.

Migration approach
Audit CRUMP data and configure HubSpot schema
FlitStack connects to your CRUMP CRM via the Dynamics 365 API and exports the full object inventory: all contacts, companies, deals, pipeline definitions, custom entities, owner list, and activity history. We cross-reference this against your HubSpot portal to identify which custom properties already exist and which need to be created before migration. If HubSpot is not on Enterprise tier, we confirm which CRUMP custom entities will map to HubSpot custom properties instead of custom objects. This step produces a schema plan — a field-level checklist your HubSpot admin executes before data lands.
Resolve CRUMP owners to HubSpot users by email
We extract the CRUMP user list from Dynamics and generate a mapping table of Dynamics User GUIDs to email addresses. Each GUID is matched against your HubSpot user roster by email. FlitStack surfaces a pre-migration owner report listing every owner that has no HubSpot match. Your team resolves these before migration day by either inviting the user to HubSpot or reassigning their records to a fallback owner. No record is placed in HubSpot without a confirmed owner ID — this prevents orphaned records that cannot be assigned after import.
Export and transform CRUMP data for HubSpot API import format
We extract CRUMP data via the Dynamics 365/CDS API using paginated requests to stay within CRUMP API rate limits. Each record type is transformed to match HubSpot's import format: field names are converted from Dynamics schema (underlines and GUID references) to HubSpot property names (camelCase), owner GUIDs are replaced with HubSpot owner IDs from the resolution table, and multi-pipeline CRUMP records are assigned to the target HubSpot pipeline based on your consolidation strategy. The transformed dataset is staged in a FlitStack migration sandbox for field-level diff before the full run.
Run a sample migration with field-level diff
A representative slice — typically 100–500 records spanning contacts, companies, deals, and a selection of activity records — migrates first. We generate a field-level diff comparing every source field value against the corresponding HubSpot property. You verify that lifecycle stage data, deal amounts, owner assignments, and pipeline-stage mapping look correct before the full run commits. Any field mapping errors discovered in the sample are corrected and the diff is re-run until the output meets your sign-off criteria. This step is the last gate before the production migration runs.
Execute full migration with delta-pickup and rollback plan
The full dataset loads into HubSpot via the HubSpot CRM API and Bulk Import API. After the initial load completes, a delta-pickup window (typically 24–48 hours) captures any records created or modified in CRUMP during the cutover window. FlitStack logs every operation to an audit trail including record count, field-level changes, and owner assignments. If reconciliation fails — record counts do not match, field values are incorrect, or owner assignments break — one-click rollback reverts the HubSpot portal to its pre-migration state. Your team keeps working in CRUMP throughout the window; FlitStack uses scoped read access only.
