Overview

What this migration involves

Constructor CRM stores accounts, contacts, leads, and opportunities in a flat object model with straightforward field structures. Microsoft Dynamics 365 Sales uses the Dataverse (Common Data Model) foundation, splitting records into Account, Contact, Lead, and Opportunity tables with relationship attributes, status codes, and process flows that govern how records advance through stages. FlitStack AI reads Constructor CRM via its export API and maps each standard field to its Dynamics 365 counterpart, creating custom fields for any Constructor properties that lack a direct equivalent. For opportunities, Constructor's pipeline stages map to Dynamics 365 Sales process stages, with probability weights and forecast categories re-applied per business unit. Custom fields migrate as Dynamics 365 custom columns, preserving data types and option-set values where present. Owner resolution uses email matching against Dynamics 365 users. Activity history—calls, emails, tasks—migrates as Dynamics 365 Activities with original timestamps and assigned owners. FlitStack does not move workflows, automations, or Power Automate flows; those require Dynamics 365-side rebuild using the exported configuration as reference. The migration runs via Dynamics 365's Bulk API (ExecuteMultiple) and Dataverse Web API, batched to stay within Power Platform request limits. A delta-pickup window of 24–48 hours captures any Constructor records modified during cutover so Dynamics 365 reflects the final state at go-live.

What's pushing teams away

  • G2 reviewers report uptime falling below 90% during some periods, which is below the threshold most modern SaaS customers tolerate.
  • Reporting is consistently called out as weak — reviewers note reports are not always available and filters are 'tough to administer and utilize'.
  • Filter management is described as difficult to manage and use effectively, slowing down ad-hoc data analysis and list-building.
  • Customers seeking strong native integrations beyond the listed Salesforce / ClickHomes / OCR / ELO connectors hit gaps and have to commission custom API work.
  • Builders that expand outside ANZ outgrow the platform's regional focus, since progress-claim conventions and tax treatments are tuned for Australian and New Zealand construction practice.

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 Constructor objects map to Microsoft Dynamics 365 Sales

Each row shows how a Constructor 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.

Constructor

Account

maps to

Microsoft Dynamics 365 Sales

Account

1:1
Fully supported

Constructor account records map directly to Dynamics 365 Account. The Account Name maps to the Account.Name field; Constructor's company address fields map to the composite address fields in Dynamics 365's address schema (street, city, state, postalcode, country). Additional standard fields such as phone, website, industry code, and employee count are also transferred to the corresponding Account attributes, preserving all core business data.

Constructor

Contact

maps to

Microsoft Dynamics 365 Sales

Contact

1:1
Fully supported

Constructor contact properties map to Dynamics 365 Contact fields. The primary key is ContactId in Dynamics. If Constructor stores multiple companies per contact, we map the primary company to AccountId (lookup) and surface additional companies as Account Contact Roles in Dynamics 365.

Constructor

Lead

maps to

Microsoft Dynamics 365 Sales

Lead

1:many
Fully supported

Constructor leads with status='new' or 'contacted' route to Dynamics 365 Lead. Leads already converted in Constructor (status='qualified') route to both Contact and Account, with the Lead record retained as a reference. We split by Constructor's lead status code value_mapping. Unqualified leads are imported as inactive Leads, preserving historical data for reporting. Lead source, rating, and custom scoring fields map to the corresponding Dynamics 365 Lead attributes.

Constructor

Opportunity

maps to

Microsoft Dynamics 365 Sales

Opportunity

1:1
Fully supported

Constructor opportunities map to Dynamics 365 Opportunities. Each Opportunity requires an AccountId (or Account lookup). Constructor's pipeline stage maps to Dynamics 365 process stage via Business Process Flow assignment per opportunity. Close date and estimated revenue map directly. Probability values and forecast category assignments transfer to the corresponding Dynamics 365 fields, and opportunity attributes are preserved as Dataverse columns. Owner resolution follows same email‑match process used for accounts and contacts.

Constructor

Pipeline

maps to

Microsoft Dynamics 365 Sales

Business Process Flow + Stage

1:1
Fully supported

Constructor's pipeline object maps to a Dynamics 365 Business Process Flow. Each Constructor pipeline creates its own BPF in Dynamics 365 so stage names, probabilities, and progression logic are scoped per pipeline. BPF activation requires Dynamics admin configuration after schema setup.

Constructor

Activity (Call)

maps to

Microsoft Dynamics 365 Sales

PhoneCall (Task)

1:1
Fully supported

Constructor call logs migrate as Dynamics 365 PhoneCall activities or Tasks with Type='Phone'. Original timestamps, call duration, owner, and parent record (Contact or Opportunity) links are preserved. Direction (inbound/outbound) maps to DirectionCode in Dynamics. Call notes are transferred to the PhoneCall description field. If the call is linked to a Contact, the regarding field points to the Contact record; if linked to an Opportunity, the regarding field references the Opportunity.

Constructor

Activity (Email)

maps to

Microsoft Dynamics 365 Sales

Email (Activity)

1:1
Fully supported

Constructor email records map to Dynamics 365 Email activities. Subject, body (plain text or HTML), sender, recipients, and timestamps migrate. Attachments are downloaded and re-uploaded to Dynamics 365 SharePoint or Notes attachments per destination's file storage configuration. Email status (sent, received, draft) is stored in the Email.Status field, and flags map to the Email.Priority attribute. If the source email references a Contact or Opportunity, the regarding field is set accordingly.

Constructor

Activity (Meeting)

maps to

Microsoft Dynamics 365 Sales

Appointment

1:1
Fully supported

Constructor meeting records map to Dynamics 365 Appointments. Start time, end time, location, organizer, and attendee list are preserved. If Constructor stores meeting notes separately, they migrate as Note records linked to the Appointment. The appointment subject and description are taken from the Constructor meeting title and details. The organizer field maps to the Dynamics 365 user who created the meeting.

Constructor

Note

maps to

Microsoft Dynamics 365 Sales

Annotation (Note)

1:1
Fully supported

Constructor notes migrate as Dynamics 365 Annotations. The note subject, body text, created date, and owner are mapped. If the note references a specific record in Constructor, we preserve the object reference as a custom field (SourceObjectId__c) for traceability. Any file attachments on the note are transferred to the related Annotation's file attachments, and note language or HTML formatting is retained in the body.

Constructor

Product

maps to

Microsoft Dynamics 365 Sales

Product

1:1
Fully supported

Constructor products map to Dynamics 365 Product records. Product name, SKU, unit price, and product type (service vs. inventory) migrate. If Constructor stores product bundles, we map those as Dynamics 365 Product Bundles with bundled items. Product description, unit, and hierarchy categories are transferred to the corresponding Dynamics 365 Product fields. Pricing details are linked through Price List Items, and stock tracking flags are set according to the inventory type.

Constructor

Custom Field (any entity)

maps to

Microsoft Dynamics 365 Sales

Custom Column (Dataverse)

1:1
Fully supported

Any Constructor custom field that has no direct Dynamics 365 equivalent is created as a custom column in the Dataverse table. We preserve the data type (string, integer, decimal, picklist, boolean, datetime) and option-set values as a Global Option Set in Dynamics 365 when applicable.

Constructor

User / Owner

maps to

Microsoft Dynamics 365 Sales

SystemUser

1:1
Fully supported

Constructor owner IDs are resolved by email address against Dynamics 365 SystemUser records. If a Constructor owner has no matching Dynamics user, we flag the record before migration—your admin either creates the Dynamics user or assigns those records to a fallback owner designated for migration.

Pair-specific challenges

  • Business Process Flow stage mapping requires Dynamics admin setup before data lands

    Constructor pipeline stages are flat text values associated with an opportunity. In Dynamics 365 Sales, each pipeline becomes a Business Process Flow (BPF) with its own set of stage names, probabilities, and progression logic. The BPF entity does not exist until your Dynamics admin creates it through the Process Designer. FlitStack AI delivers a BPF specification document showing which Constructor pipeline maps to which BPF, but the BPF activation itself is a Dynamics-side configuration step. If records land before the BPF is active, opportunities will have StageCode values with no associated process, making pipeline views incomplete until the BPF is retroactively assigned.

  • Sales Professional tier caps custom tables at 15; Enterprise required for complex custom-field schemas

    Constructor setups with more than 15 unique custom fields across entities may exceed Dynamics 365 Sales Professional's table limit (5 custom tables plus 15 total columns per table in Professional). Enterprise licensing removes this cap and allows unlimited custom tables and columns via Dataverse. FlitStack AI identifies this during the pre-migration assessment: if your Constructor schema requires more than 15 custom fields, we recommend Enterprise licensing before migration begins. Migrating to a Professional instance and then upgrading mid-migration requires a second schema-reconciliation pass that adds cost and timeline.

  • Option-set (pick-list) fields require Global Option Sets pre-created in Dynamics 365

    Constructor stores pick-list values as enumerated properties on a field. Dynamics 365 distinguishes between local option sets (scoped to one field) and Global Option Sets (reusable across fields). When migrating Constructor pick-list fields to Dynamics, each value set must either be created as a local option set during migration (which creates a separate metadata object per field) or pre-created as a Global Option Set and referenced by schema name. The difference matters for ongoing maintenance: Global Option Sets allow one change to propagate across all fields that reference them. FlitStack creates local option sets during migration by default; Global Option Sets require advance specification from your Dynamics admin.

  • Power Platform API request limits throttle bulk migration throughput

    Dynamics 365 Sales runs on Dataverse, whose API request allocation is tied to your licensing tier. Professional licenses have lower daily API request limits than Enterprise. FlitStack AI uses Bulk API ExecuteMultiple requests for batch inserts, which counts as one request per batch (up to 200 records), but Upsert and Update operations count individually. Large migrations (over 100,000 records) may hit throttling windows that extend migration clock time. We monitor throttling responses (HTTP 429) and implement exponential backoff; your Dynamics admin can increase throughput by temporarily assigning Enterprise API add-on capacity during the migration window.

  • Constructor file attachments require SharePoint or Dataverse file storage configuration

    Constructor stores file attachments against records (e.g., PDFs, images, contracts). Dynamics 365 Sales stores files either in SharePoint Online (requires SharePoint integration setup) or as Dataverse File Attributes (introduced in 2021 Release Wave 2). If your Constructor instance has attachments, FlitStack AI identifies the storage target during assessment. SharePoint integration requires your Office 365 admin to configure document libraries and site URLs in Dynamics; without this, file attachments cannot migrate directly. We can alternatively migrate attachments as Notes annotations, which preserves the content but changes the access pattern in Dynamics.

Migration approach

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

  1. Schema discovery and Dynamics 365 pre-configuration

    FlitStack AI connects to Constructor CRM via read-only API credentials and exports the full object schema: all standard and custom fields, data types, pick-list values, and relationship definitions. Simultaneously, we assess the target Dynamics 365 instance: license tier (Professional or Enterprise), existing custom tables, Business Process Flows, and Global Option Sets. We deliver a Schema Setup Plan specifying which Constructor pipelines require BPF creation, which pick-lists need Global Option Sets, and which custom fields require Dataverse columns. Your Dynamics admin (or our team acting as admin) creates the schema in Dynamics before data migration begins.

  2. Owner and user resolution

    Constructor owner records are matched against Dynamics 365 SystemUser table by email address. We generate a pre-migration Owner Resolution Report listing all matched owners, unmatched owners, and the number of records affected per owner. For unmatched owners, your team either creates the corresponding Dynamics user before migration or designates a fallback owner. No record migrates without a resolved owner. This step prevents orphaned records that have no assignable user in Dynamics.

  3. Sample migration run with field-level diff

    A representative slice of 100–500 records—spanning Accounts, Contacts, Leads, Opportunities, and a sample of activities—migrates to Dynamics 365 first. FlitStack AI generates a field-level diff comparing source Constructor values against destination Dynamics values for every mapped field. You review the diff to verify that pick-list mappings are correct, custom fields populated, BPF stage assignments accurate, and owner resolution working. Approval of the sample diff is the gate for the full migration run.

  4. Full migration with delta pickup and audit log

    The full record set migrates to Dynamics 365 using Bulk API ExecuteMultiple for inserts and Upsert for records that may already exist. FlitStack AI sequences the migration (Accounts first, then Contacts/Leads, then Opportunities, then Activities) to satisfy foreign-key dependencies. During the cutover window, Constructor remains fully operational for your team. A delta pickup phase (typically 24–48 hours) captures any records created or modified in Constructor after the full migration started. Every operation is logged in the FlitStack audit log with source record ID, destination record ID, timestamp, and operation type. One-click rollback reverts all migrated records if reconciliation reveals data integrity issues.

  5. Post-migration reconciliation and workflow export for rebuild

    After delta pickup closes, FlitStack AI runs a reconciliation report comparing Constructor record counts and a statistical sample of field values against the Dynamics 365 destination. Record counts per object, owner distribution, and stage counts are verified. Any discrepancies above the agreed tolerance trigger a re-run of the affected record set. Finally, we export Constructor workflow definitions, automation rules, and sequence configurations as JSON and PDF documentation so your Dynamics admin has a rebuild reference for Power Automate flows and Dynamics Sales automation.
