Overview
Oracle Field Service Cloud organizes service delivery around Activities (work orders), Resources (technicians), Locations, and Assets — a data model optimized for dispatch, routing, and on-site execution. Microsoft Dynamics 365 Sales is a sales CRM centered on Leads, Accounts, Contacts, Opportunities, and Cases. The migration does not move a like-for-like schema; it requires decomposing Oracle's FSM objects and redistributing them across Dynamics' CRM entities. Activities map most directly to Cases, where work-order description, priority, status, and time entries live as case fields and notes. Locations attach to Account addresses. Assets map to the Dynamics Assets table with a lookup to the customer Account. Resources (technicians) have no native CRM counterpart — FlitStack creates a custom Resource entity in Dynamics Sales so skill profiles, territories, and certification data survive the move. We migrate all standard and custom Activity fields, Asset records with installation and maintenance history, Location addresses, and Resource profiles. Workflows, routing rules, skill-based scheduling configurations, and SLA templates do not migrate — those are platform-native FSM constructs rebuilt manually in Dynamics or re-evaluated for Dynamics 365 Field Service. The migration runs against Oracle's REST API and Dynamics' Dataverse Web API, with a sample-run field-level diff before the full cutover and a 24–48-hour delta-pickup window for in-flight records.
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 Oracle Field Service Cloud 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.
Oracle Field Service Cloud
Activity (Work Order)
Microsoft Dynamics 365 Sales
Incident (Case)
1:1Oracle Activities are work orders with status, priority, time entries, parts consumed, and technician assignments. Dynamics Cases (Incidents) hold problem descriptions, priority, status, and resolution notes. FlitStack maps Activity.description to Case.title, Activity.status to Case.statuscode, Activity.priority to Case.priority, Activity.createdDate to Case.createdon (preserved as Original_Created_Date__c), and Activity.startDate/endDate to Case fields. Parts used and time entries migrate as Case notes or custom sub-entities.
Oracle Field Service Cloud
Resource
Microsoft Dynamics 365 Sales
Custom Resource__c Entity + System User
1:1Oracle Resources are technicians with skill profiles, territories, certifications, and capacity calendars. Dynamics 365 Sales has no native Resource object — technicians are System Users who may be assigned Cases but carry no skill or certification data. FlitStack creates a custom Resource__c entity in the Dynamics solution to hold skill labels, service territories, certification dates, and capacity type. The Resource's email maps to a Dynamics User for owner assignment on migrated Cases.
Oracle Field Service Cloud
Location
Microsoft Dynamics 365 Sales
Account (Address Fields)
1:1Oracle Locations represent service addresses with street, city, state, postal code, country, and geo-coordinates. Dynamics Accounts hold address fields (address1_line1, address1_city, address1_stateorprovince, address1_postalcode, address1_country). FlitStack maps Location.street to Account.address1_line1, Location.city to address1_city, and so on. Locations without a parent Organization link to a default Account or require Account pre-creation.
Oracle Field Service Cloud
Asset (Installed Base)
Microsoft Dynamics 365 Sales
Asset (msdyn_asset)
1:1Oracle Assets represent installed equipment at a customer location with name, model, serial number, installation date, warranty expiration, and customer link. Dynamics 365 Sales includes a native Asset table (msdyn_asset) with the same purpose. FlitStack maps Asset.name to msdyn_asset.name, Asset.serialNumber to msdyn_asset.msdyn_serialnumber, Asset.installDate to msdyn_asset.msdyn_installeddate, and the customer link to msdyn_asset.msdyn_customer (Account lookup). Custom Asset properties migrate as custom fields on msdyn_asset.
Oracle Field Service Cloud
Organization
Microsoft Dynamics 365 Sales
Account
1:1Oracle Organizations represent the business entities (customers) that receive service. These map directly to Dynamics Accounts — the primary company record in a sales CRM. Organization.name maps to Account.name, Organization.address to Account address fields, and Organization.phone to Account.telephone1. Additional Oracle fields such as industry classification, annual revenue, and number of employees transfer to corresponding Dynamics fields when present in the source schema. The original Oracle Organization identifier is stored in a custom field on the Account for traceability back to the source system.
Oracle Field Service Cloud
Activity Note / Attachment
Microsoft Dynamics 365 Sales
Annotation (Note) + Attachment
1:1Oracle Activity notes and file attachments migrate to Dynamics Case annotations (notes) and SharePoint-attached files. FlitStack preserves original timestamps on notes, re-uploads attachments to the linked Case's SharePoint document location, and maintains the original file name. Large attachments (>25MB per Dynamics limit) are flagged for chunked upload.
Oracle Field Service Cloud
Bucket
Microsoft Dynamics 365 Sales
Custom Field on Case (Bucket__c)
1:1Oracle Buckets are organizational containers for grouping Activities (work orders) by type, region, or business unit. Dynamics Cases have no native bucket concept. FlitStack creates a custom pick-list field (Bucket__c) on the Case entity and maps Oracle Bucket names to values in that field so the organizational grouping survives the migration.
Oracle Field Service Cloud
Inventory Item
Microsoft Dynamics 365 Sales
Product
1:1Oracle Inventory Items (parts, materials consumed on work orders) map to Dynamics Products. The item name, SKU, and unit of measure transfer as Product.name, Product.productnumber, and a custom unit field. Dynamics Products are price-list items, not inventory tracking — parts-consumed records on Oracle Activities migrate as Case notes or a custom Parts_Used__c sub-entity rather than inventory transactions.
Oracle Field Service Cloud
Custom Object (O_INT_*)
Microsoft Dynamics 365 Sales
Custom Table (Dynamics)
1:1Oracle Field Service Cloud supports custom objects created via Oracle CX configuration (following the O_INT_* naming pattern visible in Oracle's API). These custom objects, including any custom fields and relationships defined on them, map to custom tables in the Dynamics Dataverse environment. FlitStack reads the custom object's field schema from the Oracle metadata API and creates corresponding custom columns in Dynamics before data transfer.
Oracle Field Service Cloud
Route
Microsoft Dynamics 365 Sales
No Equivalent (not migrated)
1:1Oracle Routes are optimized dispatch sequences generated by Oracle's routing engine — they are execution artifacts, not durable data records. Dynamics 365 Sales has no routing or scheduling capability. Routes are not migrated. If your team relies on historical route data for analytics, FlitStack can export Route-to-Activity linkage as a reference CSV for Power BI analysis outside Dynamics.

Migration approach
Audit Oracle Field Service Cloud schema and Oracle FSC API access
FlitStack connects to your Oracle Field Service Cloud instance via OAuth 2.0 using a dedicated integration user account. We read the full object schema — Activities, Resources, Locations, Assets, Buckets, and any O_INT_* custom objects — via the REST API. We verify record counts per object, identify custom field types and constraints, confirm API rate limits on your Oracle FSC tier, and surface any Oracle FSC configurations (bucket definitions, resource territories, custom property sets) that require decisions before mapping begins. This audit generates the Oracle-side inventory used for the migration plan.
Stand up Dynamics 365 Sales custom entity and field schema
Before data moves, FlitStack provisions the custom Resource__c entity, the Bucket__c pick-list on Incident, the Parts_Used__c and Time_Entry__c sub-entities, and any custom fields required for Oracle Asset and Activity custom properties. We create these within a dedicated FlitStack managed solution in your Dynamics environment so they are cleanly removable. The custom schema is validated against the Oracle metadata audit so that every Oracle field has a corresponding Dynamics column before any data transfer occurs.
Run sample migration with field-level diff on 100–500 records
A representative slice of Oracle records — spanning Activities with various statuses and priorities, Resources across multiple territories, Assets linked to Accounts, and a sample of custom property values — migrates to Dynamics first. FlitStack generates a field-level diff report comparing source Oracle values against the destination Dynamics values for every mapped field. You review the diff to confirm Activity-to-Case field mapping, Resource-to-SystemUser owner resolution, bucket value assignment, and asset-to-account linkage before committing the full run.
Execute full migration with dependency-ordered load sequence
The full migration loads in dependency order: Locations → Accounts, then Resources (with System User resolution), then Assets (with Account lookup), then Activities (with Resource owner and Account links). This sequence ensures foreign keys resolve correctly in Dynamics — an Activity cannot link to an Account that does not yet exist. FlitStack uses Dynamics' Dataverse Web API for inserts, respecting the per-user request limits documented in the Power Platform API allocation tables. Large attachments stream directly to the SharePoint document location linked to the migrated Case record.
Activate delta-pickup window and close with audit log
After the full migration bulk insert completes, FlitStack activates a delta-pickup window of 24–48 hours during which any Oracle Activity, Resource, or Asset records modified in Oracle FSC after the snapshot date are captured and upserted into Dynamics. The migration audit log records every operation (insert, update, skip, error) with source Oracle IDs and destination Dynamics IDs for full traceability. One-click rollback reverts all Dynamics records to the pre-migration state if reconciliation against Oracle reveals a critical data integrity issue.
