Overview
GBuilder stores contacts, companies, deals, projects, and custom properties in a flat-ish object model optimized for construction and project-driven sales workflows. Dynamics 365 Sales stores the same logical entities on Dataverse — contacts, accounts, opportunities, and custom tables — with a richer relationship graph, Option Set pick-lists per business unit, and business unit security isolation. The migration carries every GBuilder standard object into its Dataverse equivalent, maps custom fields to new or existing Dynamics 365 fields (custom fields in D365 carry the new_ prefix on the entity schema name), and translates GBuilder deal stages to D365 opportunity statuses. Workflows, project-task dependencies, and automations do not migrate — FlitStack exports their definitions as a JSON reference package so your D365 admin can rebuild them in Power Automate. We use GBuilder's REST API for data extraction and Dynamics 365's Dataverse Web API for ingestion, with bulk parallel writes against Dataverse request limits. A sample migration runs first with a field-level diff; then the full cutover commits, followed by a 24–48 hour delta-pickup window that captures any GBuilder records modified during cutover before the final audit report is generated.
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 GBuilder object lands in Microsoft Dynamics 365 Sales , including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
GBuilder
Contact
Microsoft Dynamics 365 Sales
Contact
1:1GBuilder Contact maps one‑to‑one to D365 Contact, with the primary company association transferred to the Parent Account lookup. Contacts linked to multiple companies are represented through the D365 AccountContactRelationship entity or a custom junction table, ensuring each affiliation is retained. Original create timestamps and owner assignments are preserved in custom datetime and owner fields for reporting continuity.
GBuilder
Company
Microsoft Dynamics 365 Sales
Account
1:1GBuilder Company maps to D365 Account. The primary contact flag on GBuilder translates to the Primary Contact lookup on the D365 Account record. Parent-company hierarchies in GBuilder map to the Parent Account lookup in D365; circular references are flagged and resolved before commit.
GBuilder
Deal
Microsoft Dynamics 365 Sales
Opportunity
1:1GBuilder Deal maps directly to D365 Opportunity, copying the deal name into Opportunity.Name, the amount into EstimatedRevenue, and the close date into EstimatedCloseDate. The deal owner resolves to D365 OwnerId via email lookup, and any unmatched owner is flagged for admin action. Deal stage labels are translated to D365 StatusCode Option Set values, and a Business Process Flow is attached to enforce the pipeline progression.
GBuilder
Pipeline
Microsoft Dynamics 365 Sales
Business Process Flow + Option Set
1:1GBuilder pipeline stages become D365 Opportunity Status and StatusCode Option Set values. A D365 Business Process Flow is created per GBuilder pipeline so each pipeline has its own stage progression UI. FlitStack generates the BPF as part of the migration plan.
GBuilder
Project
Microsoft Dynamics 365 Sales
Custom Table (new_Project__c)
1:1GBuilder Project is a construction or project-specific object with no direct D365 equivalent. FlitStack creates a custom Dataverse table (new_Project__c) and maps project fields individually. If the D365 instance has Project Operations licensed, Project Service Administration entities are used instead.
GBuilder
Task / Activity
Microsoft Dynamics 365 Sales
Task
1:1GBuilder tasks and activity records map to D365 Task entities. The subject, description, due date, and regardingObjectId (pointing to the parent Contact, Account, or Opportunity) are preserved. Activity type discrimination (call vs. email) uses the Category or Type field on the D365 Task.
GBuilder
Note
Microsoft Dynamics 365 Sales
Annotation
1:1GBuilder notes migrate as D365 Annotation records attached to the parent Contact, Account, or Opportunity. The note text (document body), subject line, and created‑on timestamp are preserved exactly. Notes that exceed D365's inline size limit are stored as file annotations in SharePoint, with the Annotation record pointing to the SharePoint URL so users can open the content directly from the D365 form.
GBuilder
Attachment
Microsoft Dynamics 365 Sales
SharePoint Document Location + Attachment
1:1GBuilder file attachments are downloaded from the source API and uploaded to D365 SharePoint document locations that are tied to the parent record's logical folder (Contact, Account, or Opportunity). Files under the 10 MB limit are stored as D365 Email attachments on the regardingObjectId record for quick access. Original filenames, upload timestamps, and owner information are retained in the SharePoint metadata so the audit trail remains intact.
GBuilder
Custom Property (any object)
Microsoft Dynamics 365 Sales
Custom Field (new_fieldname)
1:1Every GBuilder custom property maps to a typed custom field in D365. The migration plan includes a field creation manifest (schema name, data type, Option Set binding where applicable) that the D365 admin pre-creates. Custom fields follow the new_ schema prefix convention.
GBuilder
User / Owner
Microsoft Dynamics 365 Sales
SystemUser
1:1GBuilder owner records resolve to D365 SystemUser rows by matching the owner email address to the Dataverse systemuser table. FlitStack generates a pre‑flight owner resolution report that lists matched users (green), unmatched owners (red), and a recommended fallback owner for each red entry. The admin must create D365 user accounts or designate a fallback before migration proceeds; no record commits with an unresolved owner.
GBuilder
Lead (if applicable)
Microsoft Dynamics 365 Sales
Lead
1:1If GBuilder stores leads separately from contacts, they map to D365 Lead. The lead status pick-list in GBuilder maps to D365's LeadStatus Option Set value-by-value. Upon lead qualification, D365 entity mappings carry custom fields from Lead to Contact using the OOB field mapping UI.
GBuilder
Quote / Proposal
Microsoft Dynamics 365 Sales
Quote
1:1GBuilder quotes and proposals map to D365 Quote records that are linked to the parent Opportunity. Each quote line item becomes a QuotedProduct record, preserving product name, quantity, unit price, discount percentage, and tax amount. Pricing adjustments and global discounts on the quote are transferred field‑by‑field, and the Quote's status follows the D365 Sales process so the quote lifecycle is visible in the opportunity pipeline.

Migration approach
GBuilder API extraction and data profiling
FlitStack connects to GBuilder via its REST API using the customer's API credentials (read-only scope). It paginates through large record sets, extracting contacts, companies, deals, activities, notes, and file attachments in batches to avoid time‑outs. During extraction, a data‑quality profile runs automatically, flagging missing required fields for D365, duplicate records, and parent‑company circular references. The profiling report, delivered within 24 hours of credential handoff, also lists any GBuilder custom properties that will need new_ fields in Dataverse.
D365 schema preparation and field creation manifest delivery
Based on the data profile, FlitStack generates a D365 field creation manifest listing every custom field that must exist before migration: schema name, data type, Option Set bindings, and whether the field applies to Account, Contact, Opportunity, or a custom table. The D365 admin creates these fields in the target solution before the migration run. Simultaneously, FlitStack generates the Business Process Flow XML for each GBuilder pipeline.
Owner pre-flight resolution against Dataverse systemusers
FlitStack pulls the D365 systemuser list by email address and runs a match against every GBuilder owner_id. The owner resolution report lists matched users (green), unmatched users (red), and a recommended fallback owner per unmatched record. The admin resolves red entries — either by creating D365 user accounts or designating a fallback — before the migration run proceeds. No record commits with an unresolved owner.
Sample migration with field-level diff
A representative slice of records — typically 200–500 spanning contacts, accounts, opportunities, and activities — migrates first against the live D365 target. FlitStack generates a field-level diff comparing source values to destination values for every mapped field. The customer reviews the diff to verify Option Set value mappings, BPF stage labels, owner resolution, and parent-account linkage before the full run commits.
Full migration with delta-pickup cutover window
The full dataset commits to D365 using parallel bulk writes against the Dataverse Web API, with multiple threads writing concurrently up to the platform's request limits. A 24–48 hour delta‑pickup window opens simultaneously; any GBuilder record created or modified during cutover is captured by a re‑query and written as an incremental update. Every operation is recorded in an audit log that tracks source record ID, destination record ID, timestamp, and user. If reconciliation finds mismatched counts or field values, a one‑click rollback reverts D365 to its pre‑migration snapshot, enabling corrections and a clean rerun.
