Overview
LegalServer and HighLevel are fundamentally different data architectures that share almost no object-level vocabulary. LegalServer organizes its entire data model around cases — contacts and organizations exist as sub-records linked to a case, not as standalone entities. HighLevel uses a contact-first CRM model with Companies, Contacts, and Opportunities as equal-first objects linked by lookup relationships. A LegalServer case with its associated contacts, funding codes, and timekeeping records must decompose into multiple HighLevel objects: the case becomes a HighLevel Opportunity, the primary contact lands as a HighLevel Contact with an AccountId pointing to a HighLevel Company, funding data migrates as custom fields on the Opportunity, and staff timekeeping becomes Tasks linked to the Opportunity. We extract LegalServer data via its Core API v2 (paginated at 100 results per request) and via its Reports API configured as CSV exports for complex nested structures. We then load into HighLevel using the HighLevel Contacts API and Companies API, creating Opportunities via the pipeline interface or bulk import. LegalServer workflows — the rules-based logic trees, process automation, and grant-deduction logic — have no equivalent in HighLevel's workflow engine. We document every LegalServer process step by step so your team can rebuild them in HighLevel's Workflow Builder after migration.

Object mapping
Each row shows how a LegalServer 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.
LegalServer
Person / Contact
HighLevel
Contact
1:1LegalServer contact records become HighLevel Contacts. First name, last name, email, phone, address, and date of birth map directly. The LegalServer contact ID is stored as Source_System_ID__c for traceability and delta-run de-duplication. During migration, contacts are processed first because HighLevel Opportunities require a contactId reference — all other object migrations depend on contact records being present in the system.
LegalServer
Organization
HighLevel
Company
1:1LegalServer organizations map to HighLevel Companies. Organization name, website, and address fields migrate directly. Industry, employee count, and annual revenue become custom fields because HighLevel's standard Industry pick-list does not include legal-aid sector classifications. We create a Legal_Aid_Sector__c custom field to preserve the original sector coding for reporting and grant tracking purposes.
LegalServer
Case / Matter
HighLevel
Opportunity
1:1Every LegalServer case becomes a HighLevel Opportunity. The case name maps to Opportunity Name; the case financial amount maps to Opportunity Value; case status maps to the appropriate pipeline stage in HighLevel's pipeline. Case number, matter type, case open date, and assigned staff attorney are stored as custom fields on the Opportunity.
LegalServer
Case Contact (role)
HighLevel
Contact-Opportunity Link
many:1LegalServer allows multiple contacts per case with role labels (e.g., Client, Opposing Party, Witness). HighLevel links Contacts to Opportunities via the built-in opportunity contact relationship. We preserve the role as a custom field on the link and attach the primary contact as the Opportunity's primary contact.
LegalServer
Grant / Fund Balance
HighLevel
Custom Fields on Opportunity
1:1LegalServer grants with Flat Hourly Rate or Variable Hourly Rate billing types and their current fund balances have no HighLevel native equivalent. We create custom fields (Grant_Name__c, Billing_Type__c, Fund_Balance__c) on the Opportunity object to preserve funder and budget context for grant-funded cases.
LegalServer
Funding Code / Billing Type
HighLevel
Custom Pick-list on Opportunity
1:1LegalServer funding codes such as LSC, IOLTA, Pro Bono, and Government Contract represent distinct billing arrangements with associated billing rules and funder reporting requirements. We migrate these as a custom pick-list field on the Opportunity so case managers can filter by funding source in HighLevel reports, track case volumes by funding type, and maintain funder-specific billing compliance during case management.
LegalServer
Timekeeping / Timeslip
HighLevel
Task
1:1LegalServer timekeeping records linked to cases become HighLevel Tasks. The task description carries the time entry note, the date maps to the task due date, and completion status reflects the timeslip's billed-or-unbilled state. Staff attorney is resolved by email match to HighLevel user accounts.
LegalServer
Calendar / Event
HighLevel
Calendar Event
1:1LegalServer calendar records including hearings, deadlines, appointments, and internal meetings migrate as HighLevel calendar events with original start and end times fully preserved. All event attendees are carried over and linked to the corresponding Opportunity using the case reference ID as the linking key, ensuring hearing schedules and deadlines remain associated with the correct case record after migration.
LegalServer
Outcome / Exit Code
HighLevel
Custom Field on Opportunity
1:1LegalServer captures case outcome codes and exit reasons required by funders (e.g., 'Closed — Successful', 'Referred Out', 'Income Ineligible'). These have no HighLevel native equivalent — we create a custom pick-list field (Case_Outcome__c) on the Opportunity and map each LegalServer outcome value to the closest HighLevel pick-list option.
LegalServer
Attachment / Document
HighLevel
HighLevel Files (re-upload)
1:1LegalServer stores documents on cases with HotDocs template integration and direct scanning. HighLevel Files attach to Contacts, Companies, or Opportunities but do not migrate automatically. We re-upload all attachments to the corresponding HighLevel records, preserving original filenames and linking them to the correct Opportunity.
LegalServer
Contractor / Panel Attorney
HighLevel
Contact + Custom Field
1:1LegalServer's Contractor module manages outside counsel with case assignments, fee structures, and voucher tracking. In HighLevel, contractors become standard Contacts with a Contractor__c flag custom field to distinguish them from staff, and their case assignments are tracked as Tasks linked to the relevant Opportunity. Fee structure details including flat fee, hourly, or per-case arrangements are preserved in a feeStructure__c custom pick-list field on the Contact record.
LegalServer
Staff User
HighLevel
HighLevel User
1:1LegalServer staff users are matched to HighLevel users by email address. Unmatched LegalServer staff are flagged before migration; your team either invites them to HighLevel or assigns their records to a fallback owner. No record lands without a HighLevel user as owner.

Migration approach
Map LegalServer data model to HighLevel schema and document the migration specification
FlitStack AI begins every LegalServer migration with a detailed data audit. We review your LegalServer site configuration — case types, custom fields, grant structure, funding codes, and outcome codes — and produce a written migration specification. This document maps every LegalServer object to its HighLevel equivalent, identifies custom fields that must be pre-created in HighLevel before data lands, and documents the LegalServer workflow and process steps that require manual rebuild in HighLevel's Workflow Builder.
Extract all LegalServer records via Core API v2 (paginated) and Reports API
We connect to your LegalServer site via the Core API v2, using cursor-based pagination to retrieve all contacts, organizations, cases, timekeeping records, and calendar events in batches of 100. For complex nested data like grant balances and funding code assignments, we configure LegalServer reports and export via the Reports API. LegalServer attachments are exported as a file manifest with original filenames and case reference IDs. All extracted records are staged in a migration sandbox with source record IDs preserved for traceability.
Set up HighLevel custom fields, pipelines, and contact-company-opportunity structure
Before any data loads into HighLevel, we create the custom fields identified in the migration specification — fundingCode__c, billingType__c, fundBalance__c, matterType__c, caseNumber__c, caseOutcome__c, sourceId__c, and others — on the Contact, Company, and Opportunity objects. We configure a pipeline with stages that map to your LegalServer case statuses (e.g., Intake, Open, Pending, Closed). We also create a Contractor__c flag and feeStructure__c field on Contact for panel attorney records. HighLevel must have its custom field schema in place before migration records are imported.
Run a sample migration with 50–100 representative records and validate field-level accuracy
A representative slice of records migrates first — typically covering 50–100 cases spanning different case types, funding codes, and staff assignments. We generate a field-level diff report comparing source LegalServer values against destination HighLevel values for every mapped field. You verify that case numbers, funding codes, matter types, grant balances, and owner assignments are correct before the full run commits. Any field mapping corrections are applied to the migration script before the full dataset runs.
Execute full migration, re-upload documents, run delta pickup, and validate record counts
The full migration runs contacts first (since HighLevel Opportunities require a contactId), then organizations, then cases as Opportunities with case details in custom fields. Timekeeping records migrate as Tasks linked to Opportunities. Calendar events migrate as HighLevel Events. After the full run, we run a 24–48 hour delta pickup to capture any records created or modified in LegalServer during the cutover window. We re-upload all case documents to the corresponding HighLevel records using the document mapping manifest. Final validation compares LegalServer record counts against HighLevel record counts and spot-checks field values across all case statuses and funding code types.
