Overview
Efficy CRM and Microsoft Microsoft Dynamics 365 Sales share a similar core object model — Companies map to Accounts, Contacts map 1:1, and Opportunities map to Opportunities — but they diverge sharply on Activities, Projects, and automations. Efficy stores calls, emails, meetings, and tasks as a single Activities object; Dynamics 365 splits these across Task, Event, and EmailMessage, requiring a type-aware transform during migration. Efficy's Projects and Tickets have no native equivalent in Microsoft Dynamics 365 Sales and require either the separate Project Service module or a custom entity approach agreed upon during scoping. Efficy's automation rules, follow-up sequences, and workflow triggers do not export via the API or Import Wizard and must be rebuilt in Power Automate, which we document fully for the customer's RevOps team. We extract from Efficy using the JSON-RPC Enterprise API with API key authentication, transform records to typed Dynamics Dataverse columns, and load via the Dynamics 365 REST API with batch chunking and parent-record lookup resolution.
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 Efficy CRM 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.
Efficy CRM
Company
Microsoft Dynamics 365 Sales
Account
1:1Efficy Companies map directly to Dynamics 365 Accounts. The Efficy company name becomes Account Name, the domain property becomes Website, and Industry maps to the Dynamics Industry picklist. We extract Companies first and load Accounts first in the migration sequence because Contacts and Opportunities carry foreign-key lookups to the parent Account (Efficy KCompany or equivalent). Account is created in Dynamics before any Contact batch begins so that the AccountId reference is satisfied at insert time.
Efficy CRM
Contact
Microsoft Dynamics 365 Sales
Contact
1:1Efficy Contacts map to Dynamics 365 Contact with the parent Company resolved to the AccountId lookup. Standard properties (name, email, phone, address) map to typed Contact fields; custom fields on Contact in Efficy map to custom fields on Contact in Dynamics. Multi-address records are flattened to the primary address unless the customer specifies a different strategy during scoping. We validate email format and uniqueness before insert.
Efficy CRM
Opportunity
Microsoft Dynamics 365 Sales
Opportunity
1:1Efficy Opportunities map to Dynamics 365 Opportunity with the parent Company resolved to AccountId and the primary Contact resolved to ContactId. The Efficy dealstage maps to Dynamics StageName, and pipeline assignments map to a Dynamics Sales Process or Record Type that we configure before migration. Closed-Lost reason and Closed-Won reason from Efficy custom properties become Dynamics LossReason and Win Reason fields.
Efficy CRM
Activities (calls, emails, meetings, tasks)
Microsoft Dynamics 365 Sales
Task, Event, EmailMessage
1:manyEfficy stores calls, emails, meetings, and tasks as a single Activities object with a type discriminator field. Dynamics 365 separates these into Task (Call subtype), Event, and EmailMessage, each with a distinct schema. We apply a type-aware transform during migration: call activities become Task records with TaskSubtype=Call and duration preserved; meeting activities become Event records with StartDateTime and EndDateTime; emails become EmailMessage records with IsEmailIncoming flag; standalone tasks become Task records. The WhoId and WhatId lookups are resolved to the migrated Contact and Account or Opportunity respectively.
Efficy CRM
Project
Microsoft Dynamics 365 Sales
SharePoint + Dynamics custom entity or Project Service
lossyEfficy's project management module (Kanban views, milestones, nested tasks) has no direct equivalent in Microsoft Dynamics 365 Sales . We agree on the target approach during scoping — either the separate Dynamics 365 Project Service module (if the customer has or will acquire that license) or a SharePoint document library integrated with a custom Project entity in Dataverse. We preserve project structure, milestones, and task assignments as the migration deliverable; the entity and relationship configuration is a separate configuration step before or after data migration.
Efficy CRM
Ticket
Microsoft Dynamics 365 Sales
Case or custom entity
lossyEfficy Tickets (status, priority, agent assignment, conversation history) map to Dynamics 365 Case if the destination org includes Service Cloud or Sales Enterprise/Premium. Custom ticket fields map to Case custom fields; conversation history migrates as threaded Case Comments or EmailMessages linked to the Case. If Service Cloud is not in scope, we agree on a custom entity approach during scoping and pre-create the schema before migration. We flag any Ticket with no resolution as open and preserve the original Efficy ticket ID in a custom field for cross-reference.
Efficy CRM
Custom Fields
Microsoft Dynamics 365 Sales
Custom Fields
1:1Efficy allows custom fields on all major objects (Company, Contact, Opportunity, Activities). During scoping we extract the full field schema per object — field names, types (text, picklist, numeric, date, checkbox), and picklist values — and pre-create the equivalent custom fields in Dynamics Dataverse before any data loads. Picklist values map directly; numeric and date fields map to typed Dataverse columns. We validate Dynamics field limits (maximum 500 custom fields per entity) before migration and flag any customer whose schema approaches the limit.
Efficy CRM
Document
Microsoft Dynamics 365 Sales
SharePoint or Notes
1:1Documents attached to Companies, Contacts, or Opportunities in Efficy migrate to SharePoint document libraries integrated with the relevant Dynamics Account or Contact record, or as Notes with file attachments if SharePoint is not available in the destination org. We extract the document list from Efficy via the API, resolve the parent record reference, and create ContentDocumentLink records linking each document to the migrated Account, Contact, or Opportunity. Documents without a download URL are flagged in the reconciliation report for manual handling.
Efficy CRM
User
Microsoft Dynamics 365 Sales
User
1:1Efficy Users carry roles and assignments that map to Owner or Assignee fields in Dynamics. We extract distinct Efficy owners referenced on Contacts, Opportunities, and Activities and match by email against the Dynamics destination org's User table. Owners without a matching User go to a reconciliation queue for the customer's admin to provision before record import resumes. Inactive Efficy users are excluded from the user count mapping but their historical assignments are preserved by mapping to an inactive Dynamics user record created for migration purposes.
Efficy CRM
Tag
Microsoft Dynamics 365 Sales
Multi-select picklist
lossyEfficy Tags are object-level labels that map to Dynamics multi-select picklist fields on the relevant entity. We flatten the tag list per object, create a multi-select picklist field in Dynamics Dataverse, and populate it during the Contact and Opportunity import phases. The customer chooses whether to preserve all tags or consolidate to a top-N set during scoping.
Efficy CRM
Workflow and Automations
Microsoft Dynamics 365 Sales
Not migrated — documented for rebuild
1:1Efficy automation rules, follow-up sequences, and workflow triggers do not export via the API or Import Wizard and cannot be delivered as Power Automate flows by automatic conversion. We document every active automation during discovery — trigger type, conditions, actions, and assigned owner — and deliver a written rebuild specification mapping each Efficy automation to a Power Automate flow or Dataverse workflow step. The customer's Power Platform team or a Microsoft partner rebuilds the automations post-migration.

Pair-specific challenges
Migration approach
Discovery and source audit
We audit the source Efficy CRM instance: object inventory (Companies, Contacts, Opportunities, Activities, Projects, Tickets), record counts per object, custom field schema per object, active automation count and rule type, user count and role assignments, and API key access for extraction. We pair this with a Microsoft Dynamics 365 Sales edition assessment: Sales Professional ($65/user) covers most migrations without custom objects; Sales Enterprise ($105/user) is required for advanced forecasting, Sales Insights AI, or multiple sales processes; Sales Premium ($150+/user) adds Viva Sales and deeper AI features. The discovery output is a written migration scope document that both parties sign off on before work begins.
Sandbox schema design and import sequencing plan
We design the destination schema in a Dynamics 365 Sandbox: custom fields on Account, Contact, and Opportunity (with __c API names matched to Efficy field names); Sales Processes and Record Types for each Efficy pipeline; picklist values mapped from Efficy to Dynamics; and the Activity type-split logic defined as a named transform in the migration tool. We also agree on the target approach for Projects (Project Service or SharePoint custom entity) and Tickets (Case or custom entity) during this phase. Schema is deployed via the Dynamics 365 admin center or a deployment package into the Sandbox for validation.
Sandbox migration trial and reconciliation
We run a full migration into the Dynamics Sandbox using production-like data volumes. The customer's RevOps lead reviews the migrated record counts (Accounts in, Contacts in, Opportunities in, Activities in per type), spot-checks 25-50 records per object against the Efficy source, and validates that relationship links (Contact to Account, Opportunity to Account and Contact) are intact. Any field mapping corrections, Activity type-split logic adjustments, or picklist value mismatches are fixed here. The customer signs off the sandbox results before production migration begins.
Production migration in dependency order
We run production migration in the sequenced order validated in Sandbox. Accounts load first from Efficy Companies. Contacts load second with AccountId resolved by matching Efficy KCompany to Dynamics Account. Opportunities load third with AccountId and primary ContactId resolved. Activity history loads last via the Dynamics 365 REST API with batch chunking — Task records for calls, Event records for meetings, EmailMessage records for emails, and Task records for standalone tasks — with WhoId and WhatId resolved to the migrated Contact and Account or Opportunity. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, delta sync, and automation handoff
We freeze Efficy write access during the cutover window. Any records modified in Efficy during the migration window are synced as a final delta pass. We validate the production data in Dynamics against the Efficy source record counts and relationship integrity. We deliver the automation rebuild specification document to the customer's Power Platform team or Microsoft partner. We support a one-week post-cutover window to resolve any record-level issues raised by the customer's sales team. We do not rebuild Efficy automations as Power Automate flows inside the standard migration scope; that work is a separate engagement or an internal Power Platform task.
