Overview

What this migration involves

Moving from Optimiser CRM to Microsoft Microsoft Dynamics 365 Sales is a multi-step migration constrained by Optimiser's lack of a documented public API. We extract data through the platform's built-in CSV export utility, which requires pagination across multiple export runs for datasets exceeding the per-run record limit. Microsoft Microsoft Dynamics 365 Sales uses the Account-Contact-Opportunity model with a separate Lead object, so we evaluate whether Optimiser's contact records should split into Leads and Contacts or merge directly into Contacts attached to Accounts based on qualification status. Activity history (calls, emails, meetings, notes) migrates into Microsoft Dynamics 365 Sales Tasks, Events, and EmailMessage records with parent-record resolution against the imported Contacts and Accounts. Workflows, assignment rules, and triggered sequences built in Optimiser do not migrate; we deliver a written rebuild checklist mapped to Dynamics Sales accelerator templates and Power Automate flows. Pricing for Microsoft Dynamics 365 Sales starts at $65 per user per month for Sales Professional and $105 per user per month for Sales Enterprise, with the Team Member license at $8 per user per month for read-only access.

Optimiser CRM

What's pushing teams away

  • Data import is repeatedly cited as a weak point in reviews — small businesses migrating from spreadsheets or another CRM hit friction during onboarding.
  • Outlook integration depth varies by reviewer; some report automated email-report syncing does not work as expected, forcing manual exports.
  • UI is described as 'could be slightly more user-friendly' — fine for daily use but not as polished as Pipedrive, HubSpot, or Zoho CRM at similar price points.
  • Bank-transfer-only billing complicates procurement for buyers outside the UK or those used to monthly card billing.
  • Small G2/Capterra review footprint and a UK-centric ecosystem mean buyers outside the UK have limited reference customers and partner availability.

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 Optimiser CRM objects map to Microsoft Dynamics 365 Sales

Each row shows how a Optimiser 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.

Optimiser CRM

Contact

maps to

Microsoft Dynamics 365 Sales

Contact

1:1
Fully supported

Optimiser CRM Contacts map to Microsoft Dynamics 365 Sales Contact records. Standard fields (FullName, EmailAddress, BusinessPhone, MailingAddress) transfer directly. We enumerate every Optimiser custom field during scoping via trial export, create matching custom fields in Microsoft Dynamics 365 Sales (using the field name as the display label with a custom field prefix), and map values before import. Contacts without a parent Account receive a placeholder Account during migration or are linked to an Account by domain match on the email address.

Optimiser CRM

Company

maps to

Microsoft Dynamics 365 Sales

Account

1:1
Fully supported

Optimiser CRM Company records map to Microsoft Dynamics 365 Sales Account. CompanyName maps to Account Name; website domain maps to Website. We resolve duplicate Accounts by name and domain before import using a staging dedupe pass. Account is imported before Contact so that the ParentAccountId Lookup relationship is satisfied at Contact insert time.

Optimiser CRM

Deal

maps to

Microsoft Dynamics 365 Sales

Opportunity

1:1
Fully supported

Optimiser CRM Deals map to Microsoft Dynamics 365 Sales Opportunity. Deal stage names extracted from the Optimiser instance map to a Dynamics Sales Process stage via a stage-mapping table we build during scoping. Deal value maps to Amount, expected close date maps to CloseDate, and owner assignment maps via email lookup to the Dynamics User record. Closed-Lost and Closed-Won states from Optimiser translate to the corresponding Opportunity StageName values.

Optimiser CRM

Pipeline Stage

maps to

Microsoft Dynamics 365 Sales

Stage + Sales Process

lossy
Fully supported

Optimiser's configurable pipeline stages export as a distinct list per instance. We create a Microsoft Dynamics 365 Sales Sales Process that mirrors the Optimiser stage sequence, whitelists the imported stage values in the sales process, and sets probability percentages per stage. If the customer uses multiple pipelines in Optimiser, we create corresponding Record Types in Microsoft Dynamics 365 Sales with separate Sales Processes per Record Type.

Optimiser CRM

Lead

maps to

Microsoft Dynamics 365 Sales

Lead

1:1
Fully supported

Optimiser Lead records (status, source, score fields) map to Microsoft Dynamics 365 Sales Lead. We evaluate whether Optimiser Leads represent unqualified prospects (map to Lead) or should be treated as already-qualified records (map to Contact attached to Account) based on their status field value. Lead score from Optimiser migrates to a custom integer field lead_score__c in Microsoft Dynamics 365 Sales . Lead Status values map to the configured Dynamics Lead Status picklist.

Optimiser CRM

Activity: Call

maps to

Microsoft Dynamics 365 Sales

Task (TaskSubtype = Call)

1:1
Fully supported

Optimiser call logs export as activity records with type, duration, disposition, and timestamp. Calls migrate to Microsoft Dynamics 365 Sales Task records with TaskSubtype = Call, CallDurationInSeconds, and CallDisposition preserved in custom Task fields. ActivityDate is set to the original Optimiser timestamp to preserve chronological ordering in the timeline.

Optimiser CRM

Activity: Email

maps to

Microsoft Dynamics 365 Sales

EmailMessage + Task

1:1
Fully supported

Optimiser email engagements migrate to Microsoft Dynamics 365 Sales EmailMessage records (the message content) linked to an Activity Task record (the timeline entry). The regarding (WhatId) points to the related Contact or Opportunity. Email subject, body, from, and to addresses transfer directly. Attachments download locally and re-upload to Dynamics SharePoint or as EmailAttachment records linked to the EmailMessage.

Optimiser CRM

Activity: Meeting

maps to

Microsoft Dynamics 365 Sales

Event

1:1
Fully supported

Optimiser meeting records migrate to Microsoft Dynamics 365 Sales Event with Subject, StartDateTime, EndDateTime, Location, and optional description preserved. Attendee lists from Optimiser create EventRelation records linked to the corresponding Contact or Lead. Virtual meeting links preserve as Location or as a custom field.

Optimiser CRM

Activity: Note

maps to

Microsoft Dynamics 365 Sales

Annotation

1:1
Fully supported

Optimiser Notes migrate to Microsoft Dynamics 365 Sales Annotation records (the Note body) linked via objectid to the parent Contact, Account, or Opportunity. Rich text formatting is preserved where the export supports it. Image attachments migrate as FileAttachment records linked to the Annotation.

Optimiser CRM

User/Owner

maps to

Microsoft Dynamics 365 Sales

User

1:1
Fully supported

Optimiser User records (name, email, role) map to Microsoft Dynamics 365 Sales User records via email address match. We extract every distinct owner referenced on Contact, Account, Deal, and Activity records and cross-reference against the destination org's User table. Any Optimiser owner without a corresponding Dynamics User is placed in a reconciliation queue for the customer's admin to provision before record import resumes.

Optimiser CRM

Document

maps to

Microsoft Dynamics 365 Sales

SharePoint Document or File

lossy
Fully supported

Document attachments referenced by URL or stored in Optimiser's file store are downloaded locally during the extraction phase. We re-upload files to the Microsoft Dynamics 365 Sales SharePoint document location associated with the parent Account or Opportunity. If the customer does not have SharePoint integration enabled, files attach as notes with file references preserved in Annotation.

Optimiser CRM

Tag/Label

maps to

Microsoft Dynamics 365 Sales

Multi-Select Picklist or Topic

lossy
Fully supported

Tags applied to Contacts or Deals export as label values. We migrate tags as-is into Microsoft Dynamics 365 Sales multi-select picklist fields on Contact and Opportunity. The customer chooses during scoping whether tags map to a dedicated custom multi-select field or to Topics with TopicAssignment records.

Pair-specific challenges

  • No public API means CSV extraction with per-run record limits

    Optimiser CRM does not publish a documented REST API or bulk export endpoint. We extract data via the platform's built-in CSV export utility, which limits the number of records returned per export run. For large datasets, we paginate across multiple export runs by date range or record ID offset, automating the pagination to ensure complete record coverage. This extraction method is slower than API-based migration and requires coordination with the customer to run exports in sequence without data modification during the extraction window.

  • Custom field schema varies by instance and must be enumerated individually

    Each Optimiser CRM instance defines its own custom fields on standard objects, and there is no standard reference schema. Before migration, we request a field inventory from the customer or perform a trial export to enumerate every active field across Contacts, Companies, Deals, and Activities. Fields with zero data are excluded to avoid creating dead columns in Microsoft Dynamics 365 Sales . Custom fields require pre-creation in Microsoft Dynamics 365 Sales before any data import begins, which adds 2-4 hours to scoping depending on field count.

  • Automation rules and workflows do not transfer

    Workflows, assignment rules, and triggered sequences built in Optimiser are stored in the platform's proprietary logic layer and are not accessible via CSV export or any other programmatic method. We do not migrate automations. During scoping, we document every Optimiser automation the customer identifies and map each to the equivalent Microsoft Dynamics 365 Sales accelerator or Power Automate flow template. Rebuild time is estimated at 1-2 hours per automation and falls outside the standard migration scope as a separate engagement or internal admin task.

  • Microsoft 365 integration requires post-migration configuration

    Microsoft Dynamics 365 Sales ' native Outlook email and calendar tracking, Teams collaboration, and SharePoint document management are not enabled by default during data migration. We document the required Microsoft 365 integration steps (OAuth connection to the customer's tenant, mailbox mapping, SharePoint site provisioning) but do not configure these integrations as part of the standard migration scope. Enabling them requires an active Microsoft 365 commercial subscription and tenant admin consent, which the customer must coordinate separately.

  • Optimiser activity logs may not export with full timestamp or owner attribution

    Some Optimiser CRM instances store activity records without complete owner attribution or with truncated timestamps depending on the export format selected. We validate activity export completeness during the trial extraction phase. If owner attribution is missing, we set the OwnerId to a migration service account in Microsoft Dynamics 365 Sales and flag the records for customer review. If timestamps are incomplete, we use the record creation date as a fallback ActivityDate.

Migration approach

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

  1. Discovery and data export preparation

    We audit the Optimiser CRM instance with the customer to enumerate all active objects (Contacts, Companies, Deals, Leads, Activities), custom fields, pipeline stages, and user accounts. Because Optimiser lacks a public API, we identify the CSV export settings, per-run record limits, and date-range or offset pagination strategy needed to extract the full dataset. We request a trial export to enumerate custom field names, validate data completeness, and build the field-level mapping inventory before committing to a migration timeline.

  2. Schema design and Microsoft Dynamics 365 Sales configuration

    We design the destination schema in Microsoft Dynamics 365 Sales . This includes creating custom fields to match every active Optimiser custom property, configuring Sales Processes and Record Types to mirror the Optimiser pipeline stages, provisioning the Lead status values, and setting up the Account-Contact relationship model. Schema design is validated in a Microsoft Dynamics 365 Sales sandbox environment before production migration begins. We coordinate with the customer's Microsoft partner or admin to ensure the migration user has the required Dataverse permissions.

  3. Data extraction and CSV pagination

    We run the Optimiser CSV export in paginated batches using the strategy defined during discovery. Batches are defined by date range or record ID offset to stay within the per-run record limit. Each batch is downloaded, validated for completeness (row counts, expected column headers), and stored in a staging area before transformation begins. We flag any records modified during the extraction window for a delta re-export before cutover.

  4. Data transformation and field mapping

    We transform Optimiser records into Microsoft Dynamics 365 Sales format using the mapping inventory built during discovery. Contacts receive AccountId via domain-match or placeholder Account. Deals map to Opportunities with stage translation. Activities split into Task, Event, and EmailMessage records with parent-record resolution (WhoId, WhatId) against the imported Contacts and Opportunities. Owner resolution maps Optimiser user emails to Dynamics User IDs, with unresolved owners placed in the reconciliation queue.

  5. Sandbox migration and reconciliation

    We run a full migration into a Microsoft Dynamics 365 Sales sandbox using production-like data volume. The customer's RevOps lead reviews record counts (Contacts in, Accounts in, Opportunities in, Activities in), spot-checks 25-50 records against the Optimiser source, and validates that stage values, custom field values, and activity timelines match expectations. Any mapping corrections are applied before production migration begins. Owner reconciliation resolves or escalates any remaining unresolved user mappings.

  6. Production migration and cutover

    We run production migration in dependency order: Accounts first, then Contacts with AccountId resolved, then Opportunities with AccountId and OwnerId resolved, then Activities via Dataverse API. Each phase emits a row-count reconciliation report before the next phase begins. We freeze Optimiser writes during the cutover window, run a final delta migration of any records modified during migration, and enable Microsoft Dynamics 365 Sales as the system of record. We deliver the automation rebuild checklist mapped to Dynamics Sales accelerator templates and Power Automate. A one-week hypercare window is included for reconciliation issues raised during the first production week.
