Overview
Aderant Expert is a practice-management system built for law firms: it handles clients and matters, time and expense tracking, complex billing, IOLTA trust accounting, conflict checking, and document management. HighLevel is a cloud-native CRM with contacts, companies, opportunities, tasks, and a workflow automation engine — but it has no native legal billing, no IOLTA accounting, and no matter-centric data model. The migration carries what HighLevel can store (contacts, companies, opportunities, tasks, notes, custom fields) while being explicit about what has no equivalent. We export Aderant via SQL Server direct connect or API, transform the legal data model into CRM objects, and load into HighLevel via bulk CSV or API. Client records become Contacts or Companies depending on party type. Matters become Custom Objects or Opportunities. Time entries and billing history land as Tasks or Notes with original timestamps preserved. Aderant workflows, billing rules, and trust-account logic have no HighLevel equivalent — we document them for manual rebuild but do not carry them over.
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 Aderant Expert 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.
Aderant Expert
Client
HighLevel
Contact / Company
1:manyIndividual clients (people) map to HighLevel Contact. Corporate or organizational clients map to HighLevel Company. We apply a party-type split during migration: if Aderant marks the party as an Organization, it lands as a Company; if Individual, it lands as a Contact with name fields populated. Hybrid parties (organization with primary contact) get both records linked via the relationship model.
Aderant Expert
Matter
HighLevel
Custom Object (Matter) + Opportunity
many:1Each Aderant matter becomes a HighLevel Custom Object named 'Matter' so case-specific fields, status, and hierarchy are preserved. If the firm also wants pipeline tracking, a corresponding Opportunity is created with the matter name and a nominal amount. The Custom Object ID is stored on the Opportunity for linkage. Matter hierarchy (parent/child matters) is stored as a self-referential custom field on the Matter object.
Aderant Expert
Party
HighLevel
Contact
1:1Parties stored in Aderant (opposing counsel, referring attorneys, third parties) map to HighLevel Contacts. Email and phone are carried over; if no contact info exists, the party record is created with the name and a 'Party' tag so staff can enrich it post-migration.
Aderant Expert
Bill / Invoice
HighLevel
Note + Attachment
1:1Aderant invoices cannot be recreated in HighLevel's billing engine. We export invoices as PDF or structured text and attach them to the corresponding Matter Custom Object as a Note with an attachment. Invoice number, date, amount, and status (Paid/Unpaid/Billed) are stored as fields on the note so reporting queries can filter by billing status.
Aderant Expert
Time Entry
HighLevel
Task
1:1Time entries become HighLevel Tasks with the narrative description as the task body, date performed as the due date, hours as a custom number field, and billing status (Billable/Non-billable) as a tag. Hours-to-bill amounts are preserved as a currency custom field for reporting but do not generate invoices in HighLevel.
Aderant Expert
Expense Entry
HighLevel
Task
1:1Expense records from Aderant are migrated as HighLevel Tasks following a similar pattern to time entries. Each expense receives a category tag, the monetary amount is stored as a custom currency field, and reimbursement status is recorded as a pick-list value on the task. The client and matter linkage is maintained through the appropriate HighLevel contact or custom object reference, ensuring that expense context is preserved and accessible for reporting and reconciliation in the destination system.
Aderant Expert
Trust / IOLTA Account
HighLevel
Custom Object (Trust Account)
1:1Aderant trust accounts have no HighLevel equivalent. We create a 'Trust Account' Custom Object with fields for account number, client reference, balance, and transaction history (as a JSON text block or linked notes). The object is flagged as a reference-only record — HighLevel does not enforce trust accounting rules.
Aderant Expert
Calendar / Event
HighLevel
Appointment
1:1Aderant calendar events are exported and mapped to HighLevel Appointments. Each appointment receives the subject line, start and end datetime, duration, and physical location or virtual meeting link from the original event. The assigned attorney in Aderant is mapped to the appointment owner in HighLevel. Recurring events require special handling because HighLevel lacks native support for recurring appointment templates, so each occurrence is created as a separate appointment record with the original recurrence pattern stored as a reference field for post-migration review.
Aderant Expert
Document / File
HighLevel
HighLevel Files
1:1Document metadata (filename, file type, upload date, author) is extracted from Aderant and stored as a Note on the related Matter. The actual file bytes are exported to a cloud storage location and linked via URL reference in HighLevel — files are not re-uploaded to HighLevel's native storage unless the firm specifically requests it due to storage limits.
Aderant Expert
Custom Field (Aderant)
HighLevel
Custom Field (HighLevel)
1:1Every user-defined Aderant custom field is assessed for type compatibility. Text, number, date, and pick-list fields map directly to HighLevel custom fields on the target object. Multi-select pick-lists map to HighLevel tag sets. Fields that reference other Aderant records (cross-matters) are stored as text strings on the destination object and flagged for manual verification.
Aderant Expert
User / Attorney
HighLevel
User
1:1Aderant staff and attorney records are resolved to HighLevel Users by email address. We attempt email matching first; unmatched attorneys are flagged before migration so the firm can either create HighLevel accounts or assign records to a fallback user. Billing codes and rate schedules do not transfer — those are operational settings the firm configures in HighLevel.

Migration approach
Extract Aderant data via SQL Server direct connect
FlitStack connects to the Aderant SQL Server database using administrator credentials and exports the full data set in normalized CSV format: Clients, Matters, Parties, Time Entries, Bills, Expenses, Trust Accounts, and Custom Fields. We capture foreign-key relationships (Client-to-Matter, Matter-to-Time) during extraction so the mapping layer can resolve references before loading. If the firm uses Aderant's API instead of direct DB access, we adjust the extraction method accordingly. All data is exported to a staging environment under a SHA-256 hash before transformation begins.
Assess data and build a custom mapping specification
We audit the exported data for duplicates, missing required fields, date-format inconsistencies, and party-type distribution. The mapping specification covers: Contact versus Company split rules based on party type; Matter-to-Custom-Object translation with hierarchy flagging; attorney email-to-User resolution; and custom field type compatibility assessment. The firm reviews and approves the mapping spec before any data is written to HighLevel. This step also identifies any data quality issues (incomplete addresses, missing emails) so the firm can decide whether to cleanse before migration or carry the gaps forward.
Run a sample migration against a representative slice
A sample of 100–200 records (mix of individual clients, corporate clients, open matters, closed matters, and time entries) is migrated first into a HighLevel sandbox or a designated sub-account. We generate a field-level diff comparing source values against destination values, covering all mapped fields and custom object relationships. The firm reviews the diff and confirms that matter hierarchy, attorney ownership, and time entry timestamps landed correctly. Approval of the sample unlocks the full migration run.
Execute full migration in dependency order with delta pickup
The migration runs in Aderant's dependency order: Companies and Contacts first, then Matters (Custom Objects), then Opportunities, then Tasks and Notes. Each phase is reconciled against the source record count before the next phase starts. A delta-pickup window (24–48 hours) captures any records created or modified in Aderant during the migration window. The audit log records every operation including the source Aderant ID, destination HighLevel ID, and transformation applied. One-click rollback reverts the HighLevel account to its pre-migration state if reconciliation identifies critical discrepancies.
Post-migration validation and rebuild handoff
We run a final reconciliation comparing source record counts and a random sample of field values against the destination. The firm receives a migration summary report listing all migrated records, any records that skipped or failed with reason codes, and a list of items that require manual rebuild in HighLevel (workflows, automations, IOLTA trust account tracking, conflict-check processes). We export Aderant workflow definitions as a structured document so the firm's HighLevel admin has a reference for rebuilding automations in HighLevel's workflow builder.
