Trialworks to Neos Migration: A Law-Firm Validation Runbook

A Trialworks-to-Neos migration should be driven by firm requirements and validated evidence, not an assumed end-of-life deadline. Case-management information is operationally sensitive: matters, documents, contacts, deadlines, notes, permissions, integrations, and financial workflows must be mapped and reconciled before the firm accepts cutover.

Define the decision and governance

Document why the firm is considering change, intended outcomes, sponsor, system owner, records owner, security and privacy roles, vendor responsibilities, budget, support model, and acceptance authority. Involve qualified counsel for legal hold, retention, confidentiality, and jurisdiction-specific duties. This article is operational guidance, not legal advice.

Inventory the source environment

• Active, closed, archived, and held matters.
• Documents, versions, metadata, notes, contacts, calendars, and deadlines.
• Custom fields, templates, workflows, reports, and dashboards.
• Email, accounting, intake, e-signature, scanning, and other integrations.
• Users, roles, ethical walls, external access, and service accounts.
• Retention, deletion, export, backup, and audit requirements.

Map and clean before conversion

Assembly’s migration guidance describes differences in document organization and dashboards. Resolve duplicates, invalid contacts, inconsistent naming, orphaned records, unsupported fields, and integration ownership. Freeze mapping rules and keep an exception ledger rather than silently dropping ambiguous information.

Pilot and reconcile

Convert a representative set that includes large, old, complex, active, restricted, and held matters. Reconcile matter and document counts, metadata, dates, deadlines, permissions, notes, search, reports, accounting interfaces, audit history, and exports. Require attorney, records, finance, and operations acceptance for their workflows.

Cut over with continuity

Assembly’s Neos overview describes vendor-led migration and validation; treat those as vendor statements and define the firm’s independent acceptance evidence. Plan freeze, final delta, communication, support staffing, read-only source access, rollback criteria, backup retention, and post-cutover monitoring.

Next step for your environment

Create a migration charter and representative pilot set without assuming a vendor-imposed Trialworks deadline.

Record the accountable owner, baseline, source date, decision, exceptions, acceptance evidence, and review trigger. Test consequential changes in a bounded environment, maintain a rollback path, and verify the real result before closing the work. Product names, availability, pricing, legal requirements, and security guidance can change; recheck the primary sources whenever the decision is renewed or the environment changes.

If you need an independent baseline before changing production systems, start with an ITECS technology and security assessment and keep the resulting evidence with the decision record.
