Overview
OneAdvanced Legal is a UK-focused practice management platform built for law firms — it stores clients, matters, billing, time entries, and legal-specific compliance fields in a unified schema. Pipedrive is a sales CRM that separates contacts into Persons and Organizations, tracks deals through customizable pipelines, and logs activities (calls, emails, meetings) against those records. These models diverge significantly: OneAdvanced Legal merges person and company data into a single client record, while Pipedrive requires explicit Person and Organization separation. Matters (cases) have no direct Pipedrive equivalent — they map partially to Deals or require a custom object. We migrate what exists in OneAdvanced Legal's API export: client records, matter records, time entries, documents metadata, and custom fields. Workflows, billing rules, SRA compliance templates, and integration connections do not migrate and must be rebuilt in Pipedrive or documented for manual recreation. Our migration uses a sequenced API export from OneAdvanced Legal, field-level transformation, and bulk import into Pipedrive — followed by a 24–48 hour delta-pickup window to capture in-flight changes during cutover.
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 OneAdvanced Legal object lands in Pipedrive, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
OneAdvanced Legal
Client
Pipedrive
Person + Organization
1:manyOneAdvanced Legal stores client name, firm/organization, contact details, and billing address in a single record. We split this into Pipedrive Person (individual name, email, phone) and Organization (firm name, website, industry). The split uses firm/organization name field from OneAdvanced Legal to create the Organization record first, then links the Person to it.
OneAdvanced Legal
Matter
Pipedrive
Deal
1:1OneAdvanced Legal matters include matter type, phase, risk rating, responsible fee-earner, and client link. We map each matter to a Pipedrive Deal, setting Deal title from matter reference + client name. Matter type becomes a custom field on the Deal. Pipedrive's pipeline stages substitute for OneAdvanced Legal's phase statuses, with a value-mapping table applied per matter type.
OneAdvanced Legal
Time Entry
Pipedrive
Activity (Note / Task)
1:1OneAdvanced Legal time entries (Carpe Diem) capture date, duration, fee-earner, matter link, billing status, and narrative. We create Pipedrive Activities — a Task with type 'Time Entry' for billable hours, or a Note for narrative entries — attached to the corresponding Deal. Original timestamp and fee-earner attribution preserved in activity fields.
OneAdvanced Legal
Document / Legal Form
Pipedrive
FileAttachment / Note
1:1OneAdvanced Legal document metadata (file name, document type, created date, author) migrates as Pipedrive file attachments or notes on the relevant Person or Deal. The actual file content re-uploads to Pipedrive Files if the source file is accessible via API export. File size limits and unsupported formats are flagged before migration.
OneAdvanced Legal
Invoice
Pipedrive
Custom Field on Deal
1:1OneAdvanced Legal generates and stores invoices with line items, tax, and payment status. Pipedrive has no native invoicing. We preserve invoice totals, outstanding amounts, and last-payment date as custom numeric fields on the related Deal. Firms must handle invoice recreation in a dedicated accounting tool post-migration.
OneAdvanced Legal
Client Hierarchy (Parent/Child)
Pipedrive
Organization Hierarchy
1:1OneAdvanced Legal supports hierarchical client relationships (parent firm with subsidiary offices). We map these to Pipedrive Organization hierarchy using the parent_org_id field. Circular references or orphan relationships are flagged for manual resolution before the migration run. The hierarchy mapping preserves the corporate structure while ensuring no circular loops exist in the migrated data.
OneAdvanced Legal
Matter Hierarchy (Parent Matter / Sub-Matter)
Pipedrive
Deal Hierarchy / Custom Field
1:1Nested sub-matters in OneAdvanced Legal require either a linked-Deal relationship in Pipedrive or a Parent_Matter_ID__c custom field on each Deal to preserve the hierarchy. We surface the choice before migration — linked Deals offer better UI visibility; custom fields preserve the full tree structure.
OneAdvanced Legal
Custom Client Fields
Pipedrive
Custom Person / Organization Fields
1:1OneAdvanced Legal custom properties on clients (SRA number, referral source, client risk classification) become Pipedrive custom fields on the Person or Organization object. Field types are mapped: pick-lists to drop-downs, dates to date fields, text to text fields. Pipedrive's 40-character hash keys are generated per custom field.
OneAdvanced Legal
Custom Matter Fields
Pipedrive
Custom Deal Fields
1:1Matter-level custom properties (case type, conflict-check status, indemnity-limit, statutory-body) migrate as Pipedrive Deal custom fields. Each field is created in Pipedrive's DealFields API before the migration run. Value-mapping applies for pick-list fields where OneAdvanced Legal options differ from Pipedrive's target values.
OneAdvanced Legal
User / Fee-Earner
Pipedrive
User
1:1OneAdvanced Legal fee-earners and users map to Pipedrive users by email match. Unmatched users are flagged before migration — the firm either creates a Pipedrive user account first or assigns their records to a fallback owner. Active/inactive status in OneAdvanced Legal maps to Pipedrive's user active flag.
OneAdvanced Legal
Workflow / Automation (OneAdvanced Legal)
Pipedrive
Not Migrated
1:1OneAdvanced Legal workflows for document production, compliance checks, and matter-quality file reviews (AI agents) have no Pipedrive equivalent. We export workflow definitions as a JSON reference document for the firm's Pipedrive admin to use when rebuilding automations in Pipedrive's automation engine.
OneAdvanced Legal
Integration Connections
Pipedrive
Not Migrated
1:1OneAdvanced Legal integrations (The National Will Register, Cloud Forms API, legal-forms templates) are destination-specific connections that break at migration. We document each active integration as a rebuild checklist item. The firm rebuilds these connections in Pipedrive's marketplace or via API after migration.

Migration approach
Audit OneAdvanced Legal schema and export data via API
FlitStack AI connects to your OneAdvanced Legal instance using scoped API credentials. We extract the full object list: clients, matters, time entries, documents metadata, custom fields, and user list. We profile record counts, custom field types, and matter hierarchy depth. The output is a data-dictionary worksheet that your team reviews to confirm the migration scope — including any records your team decides to exclude (closed matters older than a threshold, for example).
Design Pipedrive schema: pipelines, stages, and custom fields
Based on the OneAdvanced Legal schema audit, we deliver a Pipedrive setup plan: the pipeline structure (one pipeline per matter type or a single unified pipeline with stage groups), the stage names mapped from OneAdvanced Legal phases, and the custom fields to create on Person, Organization, and Deal objects. Your Pipedrive admin creates these before data lands. We provide the exact field names, types, and pick-list values to minimize back-and-forth.
Resolve users and build field-mapping configuration
OneAdvanced Legal fee-earners are matched to Pipedrive users by email address. Any fee-earner without a corresponding Pipedrive user account is flagged — your team creates the Pipedrive accounts or designates a fallback owner. We finalize the field-mapping configuration: which OneAdvanced Legal fields map to which Pipedrive fields, which fields require value-mapping (for pick-lists), and which fields become custom fields in Pipedrive. This configuration is reviewed and approved before the migration run.
Run sample migration with field-level diff
A representative slice — typically 100–300 records across clients, matters, and time entries — migrates first. We generate a field-level diff showing source value vs. destination value for every mapped field. Your team verifies the Person/Organization split, matter-to-Deal mapping, phase-to-stage value mapping, and custom field population. Sample results are reviewed in a sync call; any mapping adjustments are applied before the full run commits.
Execute full migration with delta-pickup window
The full dataset migrates in sequenced batches: Organizations first (since Persons and Deals reference them), then Persons (linked to Organizations), then Deals (linked to Persons and Organizations), then Activities (linked to Deals). A 24–48 hour delta-pickup window opens after the full migration completes, capturing any records created or modified in OneAdvanced Legal during the cutover. An audit log records every migrated record with source system ID for traceability. One-click rollback is available if reconciliation uncovers unexpected data quality issues.
