Overview
ResMan organizes data around Properties, Units, Tenants, Leases, and Maintenance Tickets — a model built for housing operations workflows. HighLevel organizes around Contacts, Companies, Opportunities, and Tasks — a model built for sales automation and client communication. These fundamentally different structures require careful translation during migration. We map ResMan Tenants into HighLevel Contacts with address, phone, and email preserved. ResMan Leases become HighLevel Opportunities, with lease amounts, terms, and start/end dates stored as custom fields on each deal. ResMan Properties and Units map to HighLevel Companies using a nested naming convention (PropertyName - UnitNumber) so each rental unit appears as a distinct company record. ResMan Maintenance Tickets map to HighLevel Tasks with original priority, category, and assignment preserved. Data that migrates: contacts, companies, opportunities, tasks, notes, custom fields, and file attachments. Data that requires manual rebuild: ResMan automations, workflows, payment processing rules, inspection templates, and utility billing configurations — these are destination-side schema constructs with no HighLevel equivalent. We export workflow definitions as reference documents for your team to rebuild in HighLevel's workflow builder. Migration runs via HighLevel's Bulk CSV import API with parallel processing for large datasets. A 24–48 hour delta pickup window captures any records modified during cutover. Audit logs track every operation, and one-click rollback reverts to pre-migration state if reconciliation fails.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a ResMan object lands in HighLevel, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
ResMan
Tenant
HighLevel
Contact
1:1ResMan tenants map directly to HighLevel contacts. Names, email addresses, phone numbers, and mailing addresses transfer as standard contact fields. The migration preserves the full tenant identity, including alternate phone numbers and secondary email addresses where present. Tenant role (Current, Former, Applicant, Guarantor) maps to a custom Resident_Role__c pick-list field on the HighLevel contact record, enabling pipeline segmentation by resident lifecycle stage.
ResMan
Lease
HighLevel
Opportunity
1:1Each ResMan lease becomes a HighLevel opportunity within a designated pipeline. Lease amount migrates as a custom currency field (Lease_Amount__c). Lease start and end dates map to custom date fields (Lease_Start_Date__c and Lease_End_Date__c). Security deposit, pet deposit, and any addendum fees migrate as custom number fields for reconciliation reference.
ResMan
Property
HighLevel
Company
1:1ResMan properties map to HighLevel companies using the property name as the company name. Property address maps to the company address fields. Property type (multifamily, affordable, mixed-use) maps to a custom Industry field on the company record. Each property gets a Company record regardless of unit count.
ResMan
Unit
HighLevel
Company (child record)
1:manyEach ResMan unit generates a separate HighLevel company record. The naming convention is [PropertyName] - [UnitNumber] or [UnitAddress] so each unit appears as its own company with a parent-company link to the property record. Unit status (vacant, occupied, under maintenance) maps to a custom Status__c pick-list on the unit company record.
ResMan
Maintenance Ticket
HighLevel
Task
1:1ResMan maintenance tickets migrate as HighLevel tasks. Subject line uses the ticket category and unit reference (e.g., 'Plumbing - Unit 204'). Priority, assigned vendor, and description map to task priority, assigned user, and notes fields respectively. Original ticket creation date and last-modified date are preserved as custom datetime fields.
ResMan
Vendor
HighLevel
Contact or Company
many:1ResMan vendors merge into HighLevel contacts (for individual contractors) or companies (for vendor businesses). The vendor type field routes single-person vendors to contacts and company vendors to companies, preserving contact information, trade specialty, and insurance expiry dates as custom fields for compliance tracking.
ResMan
Applicant
HighLevel
Contact
1:1ResMan applicants who have not yet signed a lease migrate as HighLevel contacts with a Resident_Role__c value of 'Applicant'. Application date, screening results, and required documents migrate as custom fields. Once a lease is signed, the role updates to 'Current Tenant' and lease opportunity records attach.
ResMan
Screening Record
HighLevel
Custom Fields on Contact
1:1ResMan tenant screening results (credit score, criminal background, income verification) have no direct HighLevel equivalent. We create a custom object Screening_Results__c linked to the contact record, storing each screening field as a custom field within that object. Your team rebuilds the screening intake workflow in HighLevel using the exported screening reference.
ResMan
Utility Billing Record
HighLevel
Custom Object
1:1ResMan utility billing records (water, electric, gas per unit) have no HighLevel equivalent. We create a custom object Utility_Billing__c linked to the unit company record. Each billing record stores utility type, billing period, amount, and payment status. Payment processing does not migrate — records serve as historical reference.
ResMan
Inspection Record
HighLevel
Task or Custom Object
1:1ResMan inspection records (move-in, move-out, annual) map to HighLevel tasks with a custom Inspection_Type__c field (Move-In, Move-Out, Annual). Inspection findings and photos attach as files to the task record. Inspection scheduling workflows must be rebuilt in HighLevel's workflow builder using the exported inspection template definitions.
ResMan
Payment History
HighLevel
CSV Export (Reference Only)
1:1ResMan payment transactions — rent payments, late fees, security deposit refunds — have no HighLevel equivalent and cannot be modeled as CRM records without distorting your pipeline. We export full payment history as a structured CSV for your accounting team to reconcile separately. This data remains in ResMan for audit compliance.
ResMan
Guarantor
HighLevel
Contact
1:1ResMan guarantors migrate as HighLevel contacts with Resident_Role__c set to 'Guarantor'. The associated tenant's contact record links to the guarantor via a custom Guarantor_Contact__c lookup field, maintaining the relational integrity between tenant and guarantor across both systems. Guarantor income documentation and supporting financial records migrate as custom fields on the guarantor contact for underwriting reference.
ResMan
Insurance Certificate
HighLevel
Custom Fields on Contact
1:1ResMan renter's insurance certificate tracking — including policy number, insurance provider name, coverage amount, and certificate expiry date — migrates as custom fields on the tenant contact record. We configure HighLevel workflow triggers based on the insurance expiry date custom field to generate automated renewal reminder sequences before coverage lapses.
ResMan
Document (Lease, Addendum, Notice)
HighLevel
File Attachment on Opportunity
1:1ResMan documents attached to leases — including signed lease agreements, addenda, notices to vacate, and renewal amendments — migrate as file attachments on the corresponding HighLevel opportunity record. We download each document from ResMan and re-upload to HighLevel Files, preserving the original file names and attachment timestamps so document history remains intact and auditable after migration.

Migration approach
Audit ResMan data inventory and build custom mapping plan
We connect to your ResMan environment via read-only API access and inventory all records: tenants, applicants, leases, properties, units, maintenance tickets, vendors, guarantors, screening records, and attachments. We compare this inventory against HighLevel's schema limits and field types. The output is a custom mapping plan that specifies which ResMan objects map to which HighLevel objects, which require custom fields or custom objects, and which records (payments, accounting) export as reference CSVs. You review and approve the mapping plan before any data moves.
Create HighLevel custom fields and custom objects
Before data ingestion, we create all required custom fields and custom objects in your HighLevel sub-account: Resident_Role__c on contacts, Lease_Amount__c and Lease_Start_Date__c on opportunities, Unit_Status__c on companies, Screening_Results__c custom object, Utility_Billing__c custom object, and Voucher_Tracking__c custom object. We also set up pipeline stages corresponding to ResMan lease statuses (Active Lease, Pending Renewal, Expired, Terminated) so opportunities land in the correct stage during import.
Resolve and validate contact and company ownership
HighLevel requires contacts to associate with companies via lookup fields. We match ResMan tenants to their corresponding unit company records by tracing the tenant-to-lease-to-unit chain in ResMan's data model. Guarantor contacts link to tenant contacts via Guarantor_Contact__c lookup fields. We flag any orphaned records — tenants without leases, units without properties — for your team to resolve before the migration commits. Vendor records that cannot be cleanly routed to contact or company objects are flagged for manual classification.
Run sample migration with field-level diff
A representative slice of 100–500 records migrates first — covering a sample property with 5–10 units, their current and former tenants, active and expired leases, and a set of maintenance tickets. We generate a field-level diff comparing source values in ResMan against destination values in HighLevel so you can verify mapping accuracy before the full run. You approve the sample before we proceed to the full migration.
Execute full migration with delta pickup and rollback readiness
The full migration runs using HighLevel's Bulk CSV import API with parallel processing for large datasets. A 24–48 hour delta pickup window opens at migration start to capture any records created or modified in ResMan during the cutover window. Audit logs record every operation. If reconciliation fails — record counts do not match, field values are corrupt, or lookup relationships break — one-click rollback reverts the HighLevel environment to its pre-migration state so you can investigate and re-run without data loss.
Deliver migration artifacts and rebuild reference package
We deliver a comprehensive migration package including: a completion report with record counts by object type and validation results, a field mapping reference document with transformation rules for all migrated fields, an exported ResMan automation definitions file for your HighLevel admin to use as a template for rebuilding workflows, a full payment history CSV for your accounting team to reconcile against your ledger, and a post-migration reconciliation checklist with field-level validation criteria. We schedule a 30-day post-migration support window with dedicated response SLAs to address any data discrepancies, mapping errors, or lookup relationship issues discovered after go-live.
