Overview
ResMan organizes property management data around leases, units, tenants, and payments — a model with no native equivalent in Microsoft Dynamics 365 Sales, which is built around the Account/Contact/Lead/Opportunity framework. Migrating from ResMan to D365 Sales means reorienting your data hierarchy: ResMan tenants become D365 Contacts, properties become Accounts, and leases become Opportunities or custom Lease tables with custom fields for unit counts, deposit amounts, and lease terms. FlitStack AI extracts ResMan data via its REST API, cleans and deduplicates tenant and lease records during staging, and loads everything into D365 using the Dataverse web API with batched inserts to stay within D365's 6,000-requests-per-user-per-5-minute rate limit. Workflows, automations, payment reminders, and inspection scheduling in ResMan do not migrate — those must be rebuilt in D365 Power Automate or manually reconfigured. The migration carries all resident contact data, lease history with term and rent fields, property and unit details, payment ledgers, and maintenance tickets. User and owner resolution happens by email match against D365 users.
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 ResMan 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.
ResMan
Tenant / Resident
Microsoft Dynamics 365 Sales
Contact
1:1ResMan tenant records map directly to D365 Contacts. Each tenant's name, email, phone, and address fields align field-for-field. Primary property association migrates as Contact.AccountId lookup — requires the Account (Property) to exist first. Secondary property associations (tenants with multiple units) surface as Account Contact Relationships in D365.
ResMan
Property / Building
Microsoft Dynamics 365 Sales
Account
1:1ResMan properties map to D365 Accounts using property name as Account Name, address fields as Account Address, and property type (multifamily, affordable, mixed-use) as Industry or a custom pick-list. ResMan parent-property hierarchies (portfolio → property) map to Account.ParentId for portfolio-level roll-up reporting in D365.
ResMan
Lease
Microsoft Dynamics 365 Sales
Opportunity
1:1ResMan leases have no direct D365 equivalent — leases are mapped to Opportunities with a custom Lease_Details__c table linked via Opportunity.LeaseDetailsId__c lookup. The Opportunity represents the lease lifecycle (lease_start to lease_end), with Amount = monthly_rent and CloseDate = lease_end_date. D365 Sales Processes and Opportunity Stages are used to model lease states (Active, Renewal Pending, Expired, Terminated).
ResMan
Lease
Microsoft Dynamics 365 Sales
Custom Table: Lease__c
1:1Because D365 has no native lease entity, FlitStack creates a Lease__c custom table in Dataverse to store ResMan lease fields that don't fit Opportunity — lease_type (Market Rate, Section 8, LIHTC, Project-Based Voucher), deposit_amount, proration_amount, lease_status, and renewal_option_count. The Lease__c table links to the Contact (tenant) and Account (property) via lookups.
ResMan
Unit
Microsoft Dynamics 365 Sales
Custom Table: Unit__c
1:1ResMan units have no D365 equivalent — each unit (apartment, townhome, etc.) is created as a Unit__c custom table record linked to the Account (property) via Property__c lookup. Unit fields mapped: unit_number (Name), beds, baths, sqft, market_rent, unit_status (Occupied, Vacant, Under Maintenance). Opportunity (Lease) links to Unit__c via Lease__c.UnitId__c to preserve the unit-to-lease relationship.
ResMan
Payment / Ledger Entry
Microsoft Dynamics 365 Sales
Task
1:1ResMan payment records are too granular for D365 native objects — FlitStack creates D365 Task records per payment with Subject = 'Lease Payment: [lease_id]', description = payment details, and scheduledate = payment_date. Actual payment amount is stored in a custom decimal field on the Task or in a custom Payment_Ledger__c table. Multiple payments per lease are tracked as a Task series linked to the Lease__c record.
ResMan
Maintenance Ticket / Work Order
Microsoft Dynamics 365 Sales
Incident (Case)
1:1ResMan maintenance tickets map to D365 Cases (Incident entity) using ticket title as Case Title, description as Case Description, priority as Case Priority, and status as Case Status. The Case's CustomerId (Account) lookup is set to the Property (Account) where the maintenance occurred. Unit association is preserved via custom Unit__c lookup on the Case.
ResMan
Property Manager / Owner
Microsoft Dynamics 365 Sales
User / Owner
1:1ResMan user records are matched to D365 users by email address. Unmatched users are flagged before migration — teams either create D365 user accounts first or assign records to a fallback owner (e.g., the property management company admin). OwnerId on Account (Property), Contact (Tenant), Opportunity (Lease), and Case (Maintenance) is resolved at migration time.
ResMan
Document / Lease Attachment
Microsoft Dynamics 365 Sales
SharePoint / Note Attachment
1:1ResMan lease documents and attachments are downloaded and re-uploaded to D365's SharePoint integration (enabled per Account or Opportunity). The document name and original upload date are preserved in SharePoint metadata. PDF leases attached to the Lease__c record are linked via the SharePoint document location on the custom table.
ResMan
Inspection Record
Microsoft Dynamics 365 Sales
Custom Table: Inspection__c
1:1ResMan inspection records have no D365 equivalent — FlitStack creates an Inspection__c custom table with fields for inspection_type (move-in, move-out, annual, maintenance-related), inspection_date, unit (Unit__c lookup), and inspector (User lookup). Inspection findings are stored as long-text notes linked to the Inspection__c record.
ResMan
Utility (ResMan Utilities module)
Microsoft Dynamics 365 Sales
Custom Table: Utility_Account__c
1:1ResMan Utilities tracks utility billing per unit — each ResMan utility account is migrated as a Utility_Account__c record linked to the Unit__c record. Fields mapped: utility_type (electric, gas, water, sewer), account_number, service_address, billing_cycle. ResMan's real-time vacated-resident billing feature is preserved as a custom flag on the utility account record.
ResMan
Screening Record
Microsoft Dynamics 365 Sales
Note / Attachment on Contact
1:1ResMan resident screening results (credit, criminal, rental history) are stored as D365 Notes attached to the Contact record. The screening report PDF is uploaded to SharePoint and linked via the note's filename field. Screening score fields are migrated as custom number fields on the Contact.

Migration approach
Audit ResMan data model and create D365 custom tables
FlitStack begins every ResMan migration by connecting to the ResMan Partner API and cataloging all active properties, units, tenants, leases, payments, and maintenance tickets. We simultaneously create the D365 custom tables (Lease__c, Unit__c, Utility_Account__c, Inspection__c) and custom fields required for the mapping. We validate that the D365 environment has sufficient custom table quota (Sales Enterprise recommended for portfolios with more than 15 custom entities). A custom-table schema plan is delivered before any data is extracted so your D365 admin can review and approve the structure.
Clean and deduplicate ResMan tenant and lease records
ResMan property management workflows create duplicate tenant records (e.g., a resident who moves out and re-applies appears as a new contact) and lease records with overlapping dates. FlitStack runs a data-quality pass on extracted records: duplicate contacts are matched by email + phone and merged before loading; lease records with duplicate unit-tenant combinations are flagged for your team to confirm the correct active lease. We deliver a pre-migration data quality report listing duplicates, missing foreign keys (orphaned tenants with no property), and records with required fields blank.
Run sample migration with field-level diff for lease and unit mapping
A representative slice of data migrates first — typically 50–200 records covering 3–5 properties, their units, active leases, a sampling of payment history, and a handful of maintenance tickets. We generate a field-level diff report comparing source ResMan values against destination D365 values for every mapped field. You verify that lease amounts, deposit figures, unit bedroom counts, and tenant email addresses appear correctly in D365 before the full migration runs. This step is also when you confirm that D365 custom pick-list values (Section 8, LIHTC, etc.) are labelled correctly in the UI.
Execute full migration with delta-pickup window
The full migration loads Properties → Accounts, Units → Unit__c, Tenants → Contacts, Leases → Opportunities + Lease__c, Payments → Tasks, and Maintenance → Cases in dependency order. A delta-pickup window of 24–48 hours runs concurrently: any new tenant, lease, or payment added to ResMan during the migration is captured and loaded into D365 before final reconciliation. FlitStack uses Dataverse $batch API with throttling-aware pacing to stay within the 6,000-requests-per-5-minute limit. An audit log records every record created, updated, or skipped with reason codes.
Reconcile record counts and validate lease-payment linkage
After the full migration and delta-pickup complete, FlitStack generates a reconciliation report comparing ResMan record counts (tenants, leases, payments, tickets) against D365 record counts, with a per-field match rate. We validate that each Opportunity (lease) is correctly linked to its Contact (tenant) via Account (property), and that Lease__c records reference their corresponding Unit__c records. Any broken lookups are re-run before your team receives the final sign-off package. A rollback snapshot is retained for 72 hours post-migration in case reconciliation reveals unexpected discrepancies.
