Overview
LegalE and Twenty CRM represent fundamentally different approaches to legal practice management. LegalE typically operates as a browser-based legal CRM with proprietary data storage, limited API access for exports, and per-seat or tiered billing that scales unpredictably as client counts grow. Twenty CRM is an open-source platform built on TypeScript, NestJS, React, and PostgreSQL — offering full data ownership, REST and GraphQL APIs, custom objects without feature gating, and pricing that remains transparent whether you self-host or use their cloud tier. The migration carries all LegalE records into Twenty's object model: contacts and companies map directly to People and Companies, matter or case records map to Opportunities with custom fields for legal-specific properties like practice area, jurisdiction, or billing arrangement. We sequence the migration so company records land first, then people linked to those companies, then opportunities referencing those people. Activity history (notes, tasks, document links) migrates as Twenty Notes and Tasks attached to the parent record. Custom legal fields from LegalE — such as bar numbers, matter types, or conflict-check results — become custom fields on the corresponding Twenty object. Workflows, templates, and automation logic do not transfer and must be rebuilt using Twenty's workflow engine. The migration runs via Twenty's CSV import API (with bulk record support for large firms), and a delta-pickup window captures any changes made during cutover.

Object mapping
Each row shows how a LegalE object lands in Twenty CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
LegalE
Contact / Client
Twenty CRM
People
1:1LegalE client records map directly to Twenty CRM People objects. Every person record carries a name, email, phone, and job title. The company association migrates as a companyId relation — the parent Company must land first so the foreign key resolves. Records without a company association attach to a default 'Unassigned' company created during setup.
LegalE
Company / Law Firm
Twenty CRM
Company
1:1LegalE company records (law firm names, corporate client organizations) map directly to Twenty CRM Companies objects. Industry, size, website, and address fields migrate as standard Company fields. Parent-child company hierarchies use the same ParentId pattern — the parent company must migrate first or circular references are flagged and resolved before the run.
LegalE
Matter / Case
Twenty CRM
Opportunity
1:1LegalE matter or case records do not have a direct One-to-One equivalent in Twenty's default Opportunity object. We map them to Opportunities and add custom fields for legal-specific properties: Practice_Area__c (text), Jurisdiction__c (text), Matter_Status__c (select), Billing_Arrangement__c (select). The Opportunity stage maps to a Matter_Stage field with legal-relevant values: Intake, Active, Pending, Closed.
LegalE
Practice Area
Twenty CRM
Custom Field on Opportunity
1:1If LegalE stores practice areas (Family Law, Corporate, Litigation, etc.) as a structured field, we create a Practice_Area__c custom select field on Twenty's Opportunity object. Values map one-to-one. If practice areas are stored as tags or free-text, they migrate as a text array in a custom field and can be converted to select options post-migration.
LegalE
Billing Arrangement
Twenty CRM
Custom Field on Opportunity
1:1Hourly, flat-fee, contingency, and pro-bono billing arrangements from LegalE migrate to a Billing_Arrangement__c custom select field on Opportunity. Value mapping is direct where the pick-list matches; non-matching values are preserved as a text fallback and can be normalized in Twenty after migration.
LegalE
Attorney / Staff Assignment
Twenty CRM
WorkspaceMember / Assignee
1:1LegalE assigns attorneys and staff to matters by user ID. Twenty CRM uses WorkspaceMember for user management. We resolve LegalE user IDs to Twenty WorkspaceMember records by email match — unmatched attorneys are flagged before migration. Unassigned matters receive a fallback assignee designated by your team during scoping.
LegalE
Note / Communication Log
Twenty CRM
Note
1:1LegalE note records and communication logs migrate as Twenty CRM Notes attached to the parent People or Opportunity record. Original timestamps, note authors, and any structured fields (conflict-check results, intake notes) are preserved. Notes with attachments require file re-upload to Twenty's storage since the attachment format differs.
LegalE
Task / To-Do
Twenty CRM
Task
1:1LegalE task records (deadlines, court filing reminders, client follow-ups) map directly to Twenty CRM Tasks linked to the parent People or Opportunity. Due dates, assignees, and completion status transfer with original timestamps. Recurring tasks that rely on LegalE automation logic are flagged for manual rebuild in Twenty.
LegalE
Document / File Attachment
Twenty CRM
Files (via Note attachment)
1:1LegalE document attachments on matters or client records are downloaded and re-uploaded to Twenty CRM. Files attach to the corresponding Note record or are stored as file links in a custom URL field. File size limits and storage costs differ between platforms — FlitStack flags oversized files before migration.
LegalE
Custom Legal Field (Conflict Check, Bar Number, etc.)
Twenty CRM
Custom Field on People or Opportunity
1:1Any LegalE custom field that does not map to a standard Twenty object field becomes a custom field created in Settings → Data Model before the migration run. FlitStack documents every custom field with its type, pick-list values, and object assignment in the pre-migration schema plan. Fields must exist before CSV import so the import mapper recognizes them.
LegalE
Client Relationship (Primary Contact, Co-Counsel)
Twenty CRM
Relation field on People
1:1LegalE may store relationship metadata between contacts (primary, co-counsel, opposing counsel). Twenty CRM supports relation fields between People records. We map primary contact relationships to a Relation record with type 'Primary Contact'. Other relationship types migrate as Relation records with the original label preserved or a normalized type value.
LegalE
Billing Record / Invoice
Twenty CRM
Custom Object (Invoice) or Opportunity custom fields
1:1If LegalE stores invoice history and line items, we assess whether to create a custom Invoice object in Twenty or store summary billing data on the Opportunity. A custom Invoice object captures invoice number, date, amount, status, and linked Opportunity. Invoice line items require a custom Line_Item__c field or a second custom object with a relation to Invoice.

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.
LegalE gotchas
Public technical documentation is sparse
Per-matter pricing makes historical-data scope matter
Document attachments require a separate retrieval path
Twenty CRM gotchas
Import order is enforced and critical
Export limited to 20,000 records and visible columns only
Soft-deleted records count toward uniqueness and trigger restores
API rate limits cap at 200 req/min on Organization tier
No native email sequences — follow-up cadences require external tools
Pair-specific challenges
Migration approach
Audit LegalE data export and relationship structure
FlitStack pulls a full export from LegalE covering all contacts, companies, matters, notes, tasks, and any custom fields in active use. We analyze the CSV structure for unstructured fields that represent structured data (e.g., conflict-check results stored in notes), identify duplicate records, and map every foreign key relationship between contacts, companies, and matters. This audit produces the migration schema plan: a document listing every field that will map directly, every field that requires a custom field in Twenty, and the load order for records with dependencies.
Set up Twenty CRM workspace and custom fields
Before any data moves, your Twenty workspace is configured to receive it. We create all custom fields identified in the audit (Practice_Area__c, Billing_Arrangement__c, Bar_Number__c, Conflict_Check__c, and any others) in Settings → Data Model. If your firm needs a custom Invoice object for billing history, that object and its fields are created at this stage. Workspace members must be invited and accepted so user assignments can resolve by email match during the migration run.
Migrate Companies first, then People, then Opportunities
We load data into Twenty in the sequence the platform requires: Companies (the 'one' side of relationships) load first, establishing companyId values. People load second, with each record's companyId pointing to the parent Company. Opportunities load third, with personId and companyId linking to the migrated records. Tasks and Notes load last, attached to their parent records. Each batch is validated against the Twenty API before the next batch starts, and any records that fail validation are flagged for remediation before the run continues.
Run sample migration with field-level diff
A representative slice — typically 200–500 records spanning all object types and including records with custom fields — migrates first. We generate a field-level diff comparing source LegalE values against the Twenty record values so you can verify that bar numbers, practice areas, matter stages, and conflict-check fields mapped correctly. You review the diff before the full run commits. If any mappings need adjustment, the diff identifies exactly which field or value map needs correction.
Execute full migration with delta pickup and rollback plan
The full record set migrates against Twenty. A delta-pickup window of 24–48 hours captures any records created or modified in LegalE during the cutover window. An audit log records every operation. One-click rollback is available if reconciliation identifies data integrity issues. After rollback is confirmed unnecessary, your team goes live in Twenty. FlitStack provides a post-migration validation report confirming record counts, relationship integrity, and a list of any records that could not migrate with their reason codes for manual resolution.
