Overview

What this migration involves

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.

GBuilder

What's pushing teams away

  • The user interface fails to present information clearly at each stage, overwhelming users instead of guiding them through workflows.
  • BIM process coordination with external software is difficult, creating friction for teams using multiple design tools on the same project.
  • Understanding and communicating project requirements is harder than expected, particularly for teams transitioning from simpler tools.

What's pulling them in

  • Deep Microsoft 365, Teams, and Outlook integration makes Microsoft Dynamics 365 Sales a natural fit for Microsoft-first organizations already invested in that ecosystem
  • Sales Enterprise and Premium tiers offer unlimited custom tables and advanced AI-driven forecasting and predictive analytics not available in lower tiers
  • Professional tier pricing at $65 per user per month offers a lower entry cost than Salesforce for SMB teams with straightforward CRM needs
  • Flexible customization options allow businesses to build bespoke apps, tailor forms and views, and integrate with other Dynamics 365 modules
  • Microsoft Copilot AI tools are embedded directly into the sales workflow on Enterprise and Premium, automating routine tasks and providing deal intelligence

Object mapping

How GBuilder objects map to Microsoft Dynamics 365 Sales

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

maps to

Microsoft Dynamics 365 Sales

Contact

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Account

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Opportunity

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Business Process Flow + Option Set

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Custom Table (new_Project__c)

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Task

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

Annotation

1:1
Fully supported

GBuilder 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

maps to

Microsoft Dynamics 365 Sales

SharePoint Document Location + Attachment

1:1
Fully supported

GBuilder 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)

maps to

Microsoft Dynamics 365 Sales

Custom Field (new_fieldname)

1:1
Fully supported

Every 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

maps to

Microsoft Dynamics 365 Sales

SystemUser

1:1
Fully supported

GBuilder 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)

maps to

Microsoft Dynamics 365 Sales

Lead

1:1
Fully supported

If 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

maps to

Microsoft Dynamics 365 Sales

Quote

1:1
Fully supported

GBuilder 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.

Pair-specific challenges

  • Business Process Flow creation is admin-side and must precede data migration

    GBuilder pipelines map to Dynamics 365 Sales Business Process Flows (BPFs), not just stage pick-lists. A BPF is a separate Dataverse entity with a stage-order graph that drives the UI in the Sales Hub app. If the BPF does not exist before opportunity records land, D365 will not enforce stage progression rules and the migrated opportunities will appear without a process context. FlitStack generates the BPF definition XML as part of the migration plan — the D365 admin must import and activate it in the solution before the opportunity migration phase begins.

  • Custom field schema names must be pre-created in the D365 solution

    GBuilder custom properties are dynamic key-value fields that have no enforced type. D365 requires every custom column to be formally created in the solution with a schema name (new_fieldname), a data type (string, integer, decimal, Option Set, etc.), and a field security level before any data loads. A GBuilder migration with 20 custom properties generates a 20-row field creation manifest. Attempting to load data into undefined fields causes a bulk API error and halts the batch. FlitStack delivers the field creation manifest at the start of the project so the admin can pre-create fields in parallel with other setup work.

  • Owner resolution by email is all-or-nothing per batch

    D365 OwnerId on every record must reference a valid Dataverse systemuser record. GBuilder owner IDs do not have a deterministic numeric correspondence to D365 systemuser IDs. FlitStack resolves owners by matching the owner email address to the D365 user record. If a GBuilder owner has no D365 user account, the record lands with a null OwnerId or a designated fallback user. This is surfaced as a pre-flight owner resolution report with a decision required before migration commits — records with unresolved owners cannot be committed in D365.

  • Option Set value mappings require manual value-by-value configuration

    GBuilder pick-list fields (deal stage, industry, activity type) use internal integer values that differ from D365 Option Set values. A naive integer-to-integer map produces incorrect labels in D365. FlitStack generates a value mapping table that lists every GBuilder pick-list label and its corresponding D365 Option Set integer value. The admin must import this map into the D365 Option Set definition UI before migration. Pick-list fields that are mapped with the wrong Option Set will display blank values in D365 forms.

  • Parent-company hierarchy requires sequential migration ordering

    GBuilder parent_company_id on Account records points to another Company record. D365 ParentAccountId also requires the referenced Account to exist at insert time. FlitStack sequences the migration as: (1) all Accounts sorted by parent relationship depth, (2) all Contacts, (3) all Opportunities. Accounts with a circular parent reference (A->B->A) are detected, flagged, and resolved to a stub Account before migration. This sequencing is mandatory and cannot be bypassed with a deferred FK strategy in D365.

Migration approach

Six steps for a successful GBuilder to Microsoft Dynamics 365 Sales data migration

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.
