Overview

What this migration involves

Moving from TeamSystem CRM to Microsoft Microsoft Dynamics 365 Sales requires first disentangling years of sales data from a platform where CRM records sit alongside accounting, payroll, and operational data in a unified schema. We identify which database tables correspond to the sales layer, extract Contacts, Companies, Opportunities, and Activities without including financial records, then load them into Microsoft Dynamics 365 Sales via the Dataverse API with owner lookups resolved against the destination User table. Custom fields, pipeline stage configurations, and activity type taxonomies require explicit field-to-field mapping since the two platforms use different schemas. Workflow rules and automation configurations in TeamSystem are not exportable as discrete data; we deliver a written inventory for the customer's admin to rebuild in Microsoft Dynamics 365 Sales using Power Automate or Dynamics workflows. Email integration data and attachments migrate by reference URL where available, subject to storage and expiry rules confirmed during scoping.

Field-level fidelity

Every standard and custom field arrives verified.

Schema-aware mapping

AI proposes the map; you confirm before any record moves.

Relationships preserved

Parent–child, lookups, and ownership stay linked.

Full activity history

Calls, emails, meetings — with original timestamps.

Attachments & notes

Documents, uploads, and inline notes move with the record.

Why teams make this switch

Two sides of the same decision

Leaving

TeamSystem CRM logo

TeamSystem CRM

What's pushing teams away

  • Some users report that the accounting modules lack the flexibility of dedicated ERP solutions, prompting moves to best-of-breed stacks.
  • Custom pricing without public tiers makes cost predictability difficult, and organizations on growth trajectories find per-user costs hard to forecast.
  • The integrated nature of the platform means leaving requires separating years of intermingled CRM and financial data, a barrier that slows adoption of better-fit alternatives.
  • Smaller teams find the administrative overhead and IT-dependent setup disproportionate to their sales automation needs compared to lighter CRMs.

Choosing

Microsoft Dynamics 365 Sales  logo

Microsoft Dynamics 365 Sales

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 TeamSystem CRM objects map to Microsoft Dynamics 365 Sales

Each row shows how a TeamSystem 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.

TeamSystem CRM

Contact

maps to

Microsoft Dynamics 365 Sales

Contact

1:1
Fully supported

TeamSystem Contact records map to Microsoft Dynamics 365 Sales Contact. We extract name, email, phone, address, ownership assignment, and any custom fields on the contact record. The email address serves as the primary dedupe key during import. Owner resolution maps TeamSystem owner IDs to Dynamics 365 User records by email match; any unresolved owner goes to a reconciliation queue for the customer's admin to provision before Contact insert proceeds.

TeamSystem CRM

Company

maps to

Microsoft Dynamics 365 Sales

Account

1:1
Fully supported

TeamSystem Company records map to Microsoft Dynamics 365 Sales Account. The company name becomes Account Name; address fields map to the standard Address compound field in Dataverse. Where TeamSystem stores a domain or website on the Company record, we map that to the Account Website field. Account is created before Contact import so the parent AccountId lookup is satisfied at the moment of Contact insert.

TeamSystem CRM

Lead

maps to

Microsoft Dynamics 365 Sales

Lead

1:1
Fully supported

TeamSystem Lead records with status, source, and scoring fields map to Dynamics 365 Lead. Lead status values from TeamSystem require explicit mapping to Dynamics 365 Lead Status picklist values since the stage taxonomy differs per organization. Any scoring field in TeamSystem migrates as a custom integer field on the Dynamics Lead for post-migration segmentation use.

TeamSystem CRM

Opportunity

maps to

Microsoft Dynamics 365 Sales

Opportunity

1:1
Fully supported

TeamSystem Opportunity records (deals with value, stage, expected close date, and pipeline association) map to Microsoft Dynamics 365 Sales Opportunity. The pipeline stage name in TeamSystem maps to a Microsoft Dynamics 365 Sales Process stage value; we create the Sales Process and whitelisted stages during configuration before migration begins so the stage reference is valid at insert time. Deal amount maps to EstimatedRevenue.

TeamSystem CRM

Pipeline

maps to

Microsoft Dynamics 365 Sales

Sales Process + Record Type

lossy
Fully supported

TeamSystem pipeline definitions (stage names, probabilities, and sequence) map to Dynamics 365 Record Types and Sales Processes. Each TeamSystem pipeline becomes a Record Type on Opportunity with a corresponding Sales Process that controls the stage dropdown values and their probabilities. We configure these in the destination Dynamics 365 org during the schema design phase before record migration.

TeamSystem CRM

Activity

maps to

Microsoft Dynamics 365 Sales

Task, EmailMessage, or custom Activity table

1:1
Fully supported

TeamSystem Activity logs (calls, emails, meetings, tasks) require value mapping since the activity type taxonomy differs between platforms. We classify each TeamSystem activity by its type attribute, then map to the corresponding Dynamics 365 entity: calls to Task with TaskSubtype=Call, emails to EmailMessage linked to a Task, meetings to Event, and standalone tasks to Task. The original TeamSystem timestamp maps to ActivityDate to preserve the timeline ordering.

TeamSystem CRM

Custom Field

maps to

Microsoft Dynamics 365 Sales

Custom Field (on corresponding Dataverse entity)

lossy
Fully supported

Organization-specific fields on any standard object in TeamSystem require pre-discovery to identify the full field registry. We query the field schema during scoping to ensure all non-standard columns are included in the export package. Each custom field maps to a Dataverse custom column of equivalent type (text, integer, decimal, date, picklist) on the target entity, created during the schema design phase before record migration.

TeamSystem CRM

User and Ownership

maps to

Microsoft Dynamics 365 Sales

User

1:1
Fully supported

TeamSystem User accounts with role assignments and record ownership do not map directly by ID to Dynamics 365 User records. We build a user mapping table during scoping that matches TeamSystem user email to the corresponding Dynamics 365 User. The customer's admin provisions any missing Dynamics 365 Users before migration. Owner resolution fails cleanly with a reconciliation report for any TeamSystem owner without a destination User match.

TeamSystem CRM

Email Integration Data

maps to

Microsoft Dynamics 365 Sales

EmailMessage + Task

1:1
Mapping required

Email tracking and inbox association data from TeamSystem migrates as EmailMessage records linked to Tasks on the Contact or Opportunity timeline. We extract email content, timestamps, and sender-recipient relationships. Full email body migration is subject to the TeamSystem integration configuration; we flag any emails that cannot be extracted due to attachment expiry or storage limits during scoping.

TeamSystem CRM

Attachment

maps to

Microsoft Dynamics 365 Sales

Note or SharePoint (via Dynamics integration)

1:1
Fully supported

Files linked to deals, contacts, or activities export by reference URL or download where accessible. Attachment migration is conditional on TeamSystem storage availability and any expiry rules set on the account. We flag any attachments that exceed storage limits or are inaccessible due to the customer's TeamSystem configuration during the discovery phase.

Pair-specific challenges

  • ERP-CRM data separation requires manual table identification

    TeamSystem stores CRM objects (Contacts, Opportunities, Activities) alongside financial records (invoices, payroll, chart-of-accounts entries) in a unified database. Extracting clean CRM exports means identifying which tables belong to the sales layer and excluding financial records from the migration package. We build a data separation map during discovery, cross-referencing table names with the customer's IT team or TeamSystem support. Organizations that have used TeamSystem's full ERP suite for several years have more intermingled data and require a longer scoping phase before any data moves.

  • TeamSystem API is not publicly documented

    TeamSystem does not publish comprehensive API documentation in English or a public developer portal for the CRM module. The public GitHub organization (CRM-in-Cloud) shows code samples for basic integrations only. For this migration, we engage TeamSystem support directly or work with the customer's IT team to obtain API credentials and endpoint documentation. In cases where API access is restricted, we fall back to a coordinated database-level export with vendor support, which adds time and requires the customer's IT team to be actively involved in the extraction phase.

  • Microsoft Dynamics 365 Sales requires custom table creation for non-standard objects

    Any TeamSystem custom objects or non-standard entity types that have no direct Microsoft Dynamics 365 Sales equivalent require Dataverse custom table creation before migration begins. This includes provisioning the table schema, custom columns, and lookup relationships to standard entities (Contact, Account, Opportunity). The schema design and deployment happen in a Dynamics 365 Sandbox first, which adds a validation step that extends the overall timeline by one to two weeks compared to migrations between platforms with fully aligned object models.

  • Workflow rules and automation configurations do not migrate

    TeamSystem workflow configurations are embedded in the ERP-CRM integration layer and are not exportable as discrete data. We document every active workflow trigger, condition, and action during the discovery phase and deliver a written inventory with recommended Dynamics 365 equivalents using Power Automate or Dynamics 365 native workflows. The customer's admin rebuilds these post-migration. We do not migrate workflow logic as code, and we do not provide post-migration admin support for the rebuild as standard scope.

Migration approach

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

  1. Discovery and data separation mapping

    We conduct a technical discovery call with the customer's IT team to identify which TeamSystem database tables correspond to the CRM layer versus the ERP-financial layer. We query the TeamSystem field registry to enumerate all standard and custom fields on Contacts, Companies, Opportunities, Leads, and Activities. We also identify the current owner assignments, pipeline configurations, and any email or attachment storage limits. The output is a written data separation map and migration scope that explicitly lists which tables and fields enter the export package.

  2. API credential acquisition and extraction

    We engage TeamSystem support or work with the customer's IT team to obtain API credentials and endpoint documentation for the CRM module. Where API access is restricted, we coordinate a database-level export with vendor support. We run a pilot extraction of 50-100 records per object to validate field coverage and confirm the data separation map is accurate before running the full export.

  3. Schema design in Dynamics 365 Sandbox

    We provision the destination Microsoft Dynamics 365 Sales environment in a Sandbox, creating any custom tables, custom columns, Record Types, and Sales Processes required to receive the TeamSystem data. We design the Lead and Contact field mappings, opportunity stage configurations, and user mapping table. Schema is validated in Sandbox before production migration begins.

  4. Sandbox migration and reconciliation

    We run a full migration into the Dynamics 365 Sandbox using production-like data volumes. The customer's RevOps or CRM admin reconciles record counts (Contacts, Accounts, Opportunities, Activities), spot-checks 25-50 records against the TeamSystem source, and validates that owner assignments, stage probabilities, and activity timestamps are correct. Schema corrections and mapping adjustments happen here, not in production.

  5. Owner provisioning and user reconciliation

    We extract every distinct TeamSystem owner referenced across Contacts, Companies, Opportunities, and Activities and match by email against the Microsoft Dynamics 365 Sales User table. Owners without a matching Dynamics 365 User go to a reconciliation queue. The customer's Dynamics 365 admin provisions any missing Users before production migration resumes. Migration cannot proceed past record insert without resolved OwnerId references.

  6. Production migration in dependency order

    We run production migration in record-dependency order: Accounts (from TeamSystem Companies), Contacts (with AccountId resolved), Leads, Opportunities (with AccountId, OwnerId, and RecordTypeId resolved), Activity history (Tasks, Events, EmailMessages via Dataverse API), then Custom Objects last since they often have lookups to standard entities. Each phase emits a row-count reconciliation report before the next phase begins. The TeamSystem CRM is set to read-only during cutover, and we run a final delta migration of any records modified during the migration window.

  7. Cutover, validation, and workflow rebuild handoff

    We enable Microsoft Dynamics 365 Sales as the system of record and deliver the workflow and automation inventory document to the customer's admin team. We support a one-week hypercare window where we resolve any data quality issues raised by the sales team. We do not rebuild TeamSystem workflow rules as Power Automate flows or Dynamics 365 native workflows inside the migration scope; that is a separate engagement. Reports and dashboards do not migrate and are listed in the handoff document for the admin to rebuild in Dynamics 365's reporting workspace.

Migrations land between five and eight weeks for accounts under 15,000 Contacts, 4,000 Opportunities, and a clean CRM-only extract with no ERP entanglement. Migrations with years of intermingled ERP-CRM data requiring manual table identification, large activity histories (over 200,000 records), or organizations with 20+ active users needing owner reconciliation extend to ten to eighteen weeks because of the discovery overhead for data separation and the lack of public API documentation on TeamSystem.
