Overview
Lexis Affinity and HighLevel occupy fundamentally different product categories, which makes this migration more involved than a CRM-to-CRM move. Lexis Affinity is a legal practice management system built around matters (cases), billable time entries, trust accounting ledgers, and document workflows tied to a firm's billing cycle. HighLevel is an all-in-one marketing and sales CRM built around contacts, companies, opportunities in customizable pipelines, and workflow automation triggers. There is no native billing module in HighLevel, no trust accounting equivalent, and no concept of matters as first-class records — those constructs have to be expressed as opportunities with custom fields or external references. FlitStack AI uses Lexis Affinity's API to extract contacts, client records, matter data, and time entries, then maps them into HighLevel's contact, company, and opportunity objects. We flag any complex or non-transferable data — billing invoices, trust accounting ledgers, automation rules — for manual rebuild rather than migrating dead or broken references. A 24–48 hour delta pickup window closes after the initial load so in-flight changes during cutover land in HighLevel before go-live.
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 Lexis Affinity 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.
Lexis Affinity
Contact (Client Person)
HighLevel
Contact
1:1Lexis Affinity client person records map directly to HighLevel contacts. We match by email address and flag any duplicate email addresses found across multiple client records before importing, so your team decides how to handle shared-contact scenarios. During the mapping process, we preserve the full contact name, all phone numbers including mobile, physical address components, and any custom fields associated with the client person record. If a contact lacks an email address, we attempt matching on name and phone combination as a fallback, flagging any remaining ambiguous matches for manual resolution before the migration load begins.
Lexis Affinity
Company (Client Organization)
HighLevel
Company
1:1Lexis Affinity client organization records map to HighLevel companies. The primary billing address and phone number carry over as the company address and phone. Multiple offices per client in Lexis Affinity require manual consolidation or creation of separate company records in HighLevel.
Lexis Affinity
Matter (Case File)
HighLevel
Opportunity
1:1Lexis Affinity matters have no direct equivalent in HighLevel — HighLevel has no native matter concept. We map each matter to an opportunity record using the matter name as the opportunity name, the matter number as a custom reference field (Matter_ID__c), and the matter status as the pipeline stage. Matter-specific custom fields become HighLevel custom opportunity fields.
Lexis Affinity
Matter Status
HighLevel
Pipeline Stage
1:1Matter status values (Active, Pending, Closed, On Hold) map to HighLevel pipeline stages via a value-by-value lookup table. Each pipeline in HighLevel can have its own stage names, so we configure a 'Legal Matters' pipeline with stages that mirror your matter lifecycle. Unmapped status values route to a default stage and are flagged for review.
Lexis Affinity
Time Entry
HighLevel
Note (on Opportunity)
1:1Time entries are high-value records containing attorney hours, activity descriptions, and billing rates. We convert each time entry to a HighLevel note attached to the opportunity, preserving the date, hours, and narrative. The billable amount is stored in a custom currency field (Billable_Hours__c) on the note so it appears in HighLevel reporting without being confused with opportunity monetary values.
Lexis Affinity
Trust Account Ledger
HighLevel
Custom Field (Contact)
1:1Trust accounting ledgers and client IOLTA account balances have no native equivalent in HighLevel. We preserve the current trust balance as a custom currency field (Trust_Balance__c) on the contact record for reference. Historical ledger entries export as a CSV that your team can store alongside the HighLevel record for compliance purposes.
Lexis Affinity
Invoice / Bill
HighLevel
External Reference
1:1Lexis Affinity generates invoices tied to matters, time entries, and disbursements. HighLevel has no invoice generation module. We export invoice records as a structured CSV containing invoice number, date, amount, status, and linked matter ID. This CSV can be imported into a separate accounting tool or kept as a financial reference document attached to the opportunity.
Lexis Affinity
Document (File Attachment)
HighLevel
File (on Contact/Opportunity)
1:1Documents attached to matters and contacts in Lexis Affinity are downloaded and re-uploaded to HighLevel's file storage linked to the corresponding contact or opportunity record. Large document repositories may require a document management strategy beyond HighLevel's native file storage. We flag any files exceeding HighLevel's file size limits before migration.
Lexis Affinity
User / Staff Member
HighLevel
User
1:1Lexis Affinity staff members are matched to HighLevel users by email address. Unmatched staff members are flagged before migration — your team either creates HighLevel user accounts in advance or assigns records to a fallback user. Staff role and permission levels do not transfer and must be reconfigured in HighLevel's access settings.
Lexis Affinity
Custom Field (Matter / Contact Level)
HighLevel
Custom Field
1:1Any Lexis Affinity custom fields on matters or contacts that have no standard HighLevel equivalent are created as custom fields in HighLevel before migration. Text fields, number fields, date fields, and pick-list fields map directly; complex multi-column or table-style custom fields in Lexis Affinity require flattening into individual custom fields or storing as a JSON-formatted text field.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Lexis Affinity gotchas
Records and Safe Custody module creates migration lock-in
DataForm custom field schemas are per-firm and must be reverse-engineered
Trust account sub-account types map differently to destination ledgers
Workflow automations do not export and must be rebuilt manually
HighLevel gotchas
Sub-account architecture creates isolated data silos per client
Usage-based telecom and AI costs are not in the subscription price
Workflows have no native equivalent in most destination CRMs
API rate limits cap bulk migration throughput at 100 requests per 10 seconds per sub-account
White-label configuration and branding assets do not export via API
Pair-specific challenges
Migration approach
Extract and back up Lexis Affinity data
FlitStack AI connects to your Lexis Affinity instance via scoped read-only API access and exports all contacts, client organizations, matters, time entries, custom field definitions, and file attachments. We preserve original create and modify timestamps and capture the full Lexis Affinity internal ID for every record so the source record can be traced back after migration. A full backup is written before any transformation begins — no data is overwritten or deleted from the source system during the extraction phase.
Analyze data model and build the mapping specification
We analyze the exported Lexis Affinity schema — standard fields, custom fields, matter types, and time entry structures — and produce a data model analysis document. This document defines the object mapping (matter → opportunity, client → contact), field-by-field transformation rules, value-mapping tables for matter status, and a list of records that have no HighLevel equivalent and will be exported to CSV. Your team reviews and approves the mapping specification before any data is loaded.
Configure HighLevel custom fields and pipelines
Before data lands in HighLevel, we create the custom fields (Matter_ID__c, Practice_Area__c, Trust_Balance__c, Billable_Hours__c, Billing_Rate__c) and the 'Legal Matters' pipeline with stages that map to your Lexis Affinity matter statuses. We also create the tag taxonomy that mirrors your matter labels and client types. This step runs in parallel with the mapping specification review so the HighLevel schema is ready when the migration load begins.
Run sample migration and validate field-level accuracy
A representative sample — typically 100–500 records spanning contacts, companies, matters, and time entries — migrates first. We generate a field-level diff showing the source value, the mapped value, and any transformation applied. You verify that matter status mapping is correct, custom fields landed in the right HighLevel objects, time entries are readable in the opportunity notes, and owner resolution by email match produced the expected HighLevel user assignments. We adjust the mapping and re-run the sample until the diff passes your sign-off criteria.
Execute full migration with delta pickup window
The full data load runs against HighLevel. A delta pickup window of 24–48 hours runs concurrently and captures any records created or modified in Lexis Affinity during the cutover period — new client contacts, updated matter statuses, or late time entries. After the window closes, we run a final reconciliation comparing record counts, field completeness, and tag coverage between source and destination. An audit log documents every operation; one-click rollback is available if reconciliation identifies critical gaps.
