Migrate your OneAdvanced Legal data
UK and Irish law-firm practice management platform combining case management, integrated accounts, and time capture in a single cloud-native subscription.
In its favor
Why people choose OneAdvanced Legal
The signal that keeps OneAdvanced Legal on the shortlist. Sourced from G2, Capterra, and customer scoping calls.
Per-user per-month subscription model means firms pay only for active seats, making cost predictable as headcount changes over the contract term.
Fully integrated UK-compliant accounts and billing within the same platform eliminates reconciliation friction between practice management and cashier functions.
Cloud-native architecture on Microsoft Azure with UK South primary storage and UK North redundancy meets common SRA data-residency requirements out of the box.
Managed migration services bundled under the Customer for Life programme reduce the internal IT burden during technology transition projects.
Role-based workflows and proactive threat monitoring are included at no additional module cost, reducing the attack surface during migration cutover windows.
Firms report that the platform is harder to exit than to enter, with export scoping and data extraction requiring significant internal effort to scope correctly.
Support access via the portal and telephone system has frustrated some users following platform changes, with reports of unreachable support teams during critical periods.
Custom workflows and bespoke process configurations built over years create migration complexity that requires detailed audit before any data move can proceed safely.

What gets migrated
OneAdvanced Legal object support
Object-by-object support for OneAdvanced Legal migrations. Per-pair details surface during scoping.
Clients
Fully supportedClient records in OneAdvanced Legal carry contact details, matter associations, and billing profiles. The standard schema is stable and well-structured. We migrate Client records 1:1 and map any custom client properties to equivalent destination fields.
Matters
Fully supportedMatters link clients to practice areas, fee earners, and task hierarchies. The matter structure includes stage status, associated documents, and billing records. We preserve the full matter tree including child tasks during migration.
Time Entries
Mapping requiredTime Capture (formerly Carpe Diem) records billable time with validation workflows before posting to accounts. Entry formats, validation rules, and posting states vary by firm configuration. We audit the time entry schema during scoping and map posting states explicitly so WIP balances are not distorted at go-live.
Bill of Costs
Mapping requiredCosts drafting on OneAdvanced Legal uses structured line-item records tied to matter stages. Exchange rates, jurisdiction-specific cost codes, and VAT treatment require field-level mapping between source and destination schemas.
Trust Accounts
Mapping requiredLegal Cashier manages client money with SAR-compliant accounts, automated processes, and exportable reconciliation reports. Trust account balances and transaction histories require careful sequencing to avoid reconciliation gaps at the point of cutover.
Documents
Mapping requiredSharePoint-connected document storage with deep search and secure sharing requires us to audit the document library structure, version history, and Laserform template associations before migration. Template field mappings must be preserved separately from the files themselves.
Users and Fee Earners
Fully supportedUser accounts include role-based permissions, department assignments, and fee earner billing rates. We migrate user records with their roles intact and remap owner assignments on matters and time entries during the import sequence.
Custom Properties
Mapping requiredFirms frequently add custom fields to Clients, Matters, and Documents outside the standard schema. These are not always visible in export utilities. We explicitly audit for custom properties during discovery so they are not silently dropped at migration time.
Wills Register Records
Mapping requiredThe National Will Register data sits on Rackspace-hosted servers separate from the main Azure platform. Will registration records, testator details, and associated document links require a separate extraction step from the core matter migration.
Integration Endpoints
Mapping requiredLaserform API and Legal Forms API expose field data for document population. These endpoints allow us to retrieve and remap form field associations, but a dedicated integration audit is required to capture all active form templates in use.
