Overview
OneAdvanced Legal is a practice-management and case-management platform built for UK and Irish law firms, with strong time-capture, integrated billing, and compliance features baked into a single cloud-native stack. Salesforce Sales Cloud has no native legal-matter model — matters, bills, time entries, and client-money accounting have to be built from Account, Case, custom objects, and junction relationships. The migration carries OneAdvanced's clients, contacts, matters, time entries, bills, and document attachments into Salesforce's Account-Case-Contact framework, supplemented by custom objects for billable time and legal-specific properties. Workflows — including matter-opening checklists, bill-review approvals, and compliance alerts — do not migrate and must be rebuilt in Salesforce Flow or Process Builder. FlitStack sequences the migration so foreign keys resolve correctly: Accounts first, then Contacts, then Cases with the matter hierarchy, then time entries linked via a custom junction object. The delta-pickup window captures any new time entries or bill adjustments made in OneAdvanced during cutover so Salesforce reflects the final ledger state.
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 Salesforce Sales Cloud, 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
Salesforce Sales Cloud
Account
1:1OneAdvanced Clients map directly to Salesforce Accounts. The firm name maps to Account.Name, and the primary contact on the Account gets the client-side contact role. Multi-address clients collapse to one primary billing address; additional locations stored as custom address fields or Account Contact Relations.
OneAdvanced Legal
Contact
Salesforce Sales Cloud
Contact
1:1OneAdvanced Contact records map directly to Salesforce Contacts in a one-to-one relationship. Since every Contact requires an AccountId in Salesforce, FlitStack first resolves each contact's parent Client record to the corresponding migrated Account using name matching. This resolution step ensures that AccountId is populated correctly before contacts are written to Salesforce. Any contacts where the parent Client cannot be matched to an existing Account are flagged in the unresolved-contacts report for manual review and resolution.
OneAdvanced Legal
Matter
Salesforce Sales Cloud
Case
1:1OneAdvanced Matter is the central work unit; Salesforce Case is the closest standard object. FlitStack creates a Case for every Matter, sets a RecordType of 'Legal Matter', and populates Matter-specific custom fields (Matter_Type__c, Jurisdiction__c, Opposing_Party__c) from OneAdvanced properties. The Case.AccountId links to the client Account.
OneAdvanced Legal
Matter hierarchy (parent/child matters)
Salesforce Sales Cloud
Case parent lookup
1:1OneAdvanced supports sub-matters (a litigation matter with linked advisory sub-matters). Salesforce Case has a ParentCaseId field that maps to this — the top-level matter migrates first, then child matters reference it via ParentCaseId. Circular parentage is flagged and resolved to the most senior matter.
OneAdvanced Legal
Bill
Salesforce Sales Cloud
Custom Invoice object (Invoice__c)
1:1OneAdvanced Bills with line items, VAT treatment, and payment status have no Salesforce standard equivalent. FlitStack creates an Invoice__c custom object with a lookup to the Case (matter) and Account. Each line item becomes an Invoice_Line_Item__c record or is stored as a JSON body on the Invoice record depending on the line-item count.
OneAdvanced Legal
Time Entry
Salesforce Sales Cloud
Custom Time_Entry__c object
1:1OneAdvanced time entries track hours, rate, narrative, WIP/billed status, and fee earner per matter. Salesforce has no standard billable-time object. FlitStack creates a Time_Entry__c custom object with a lookup to the Case (Matter__c) and the fee-earner as OwnerId. Billable_Flag__c, Rate__c, Hours__c, and Narrative__c carry the full entry data.
OneAdvanced Legal
Document / File
Salesforce Sales Cloud
Salesforce Files (ContentDocument / ContentVersion)
1:1OneAdvanced documents attached to matters re-upload as Salesforce Files (ContentVersion uploaded to the Case or Account). File size limits apply — OneAdvanced documents exceeding 25 MB are split or linked externally. Metadata including original filename, upload date, and author is preserved as ContentVersion fields.
OneAdvanced Legal
Custom matter properties
Salesforce Sales Cloud
Custom fields on Case (Matter__c)
1:1OneAdvanced matter-level custom properties — such as Case_Type__c, Practice_Area__c, Court__c, or Counsel__c — migrate as custom fields on the Case object in Salesforce. FlitStack creates each custom field with the appropriate type (pick-list, text, lookup) before the data migration run.
OneAdvanced Legal
Fee Earner / Staff
Salesforce Sales Cloud
User
1:1OneAdvanced staff with time-capture permissions map to Salesforce Users by email address. FlitStack generates an unresolved-owner report before migration: any OneAdvanced staff whose email does not match an existing Salesforce User is flagged so the firm can create the Salesforce User or assign a fallback owner before the run commits.
OneAdvanced Legal
Workflow / Matter checklist
Salesforce Sales Cloud
No equivalent
1:1OneAdvanced matter-opening checklists, bill-review approval chains, and compliance alert workflows rely on platform-specific configurations that have no equivalent in Salesforce's standard object model. These automated processes cannot be exported or migrated directly and must be reconstructed using Salesforce Flow, including Flow screens, decisions, and action elements. FlitStack exports every active OneAdvanced workflow definition as a structured reference document containing the workflow name, triggering conditions, approval stages, and associated field values, providing the firm's Salesforce administrator or implementation partner with a complete blueprint for rebuilding each process in Flow.

Migration approach
Discover OneAdvanced schema and Salesforce target configuration
FlitStack reads your OneAdvanced export or API payload to inventory every client, matter, time-entry, bill, and custom property. We simultaneously work with your Salesforce admin to confirm the Case RecordType plan, custom object creation (Time_Entry__c, Invoice__c, Trust_Account__c), and field-level validation rules that will apply to the incoming data. This step produces a signed-off migration plan and field-mapping spreadsheet before any data moves.
Create Salesforce custom objects and fields
FlitStack creates the custom objects and fields identified in the discovery step — Time_Entry__c with its Matter__c lookup, Invoice__c with payment-status and VAT fields, Trust_Account__c with balance tracking — inside your Salesforce sandbox first. We validate that each custom field's type matches the source data (currency fields for amounts, pick-lists for status values, date fields for timestamps) and that the page layouts include the new fields before the schema is pushed to production.
Resolve fee-earner owners and validate user accounts
Every time-entry, matter, and bill in OneAdvanced is owned by a fee earner. FlitStack resolves each fee earner's email address against your Salesforce User list. Any email that does not match an existing Salesforce User generates an unresolved-owner report — the firm either creates the Salesforce User before the migration or assigns a fallback owner. No data record lands in Salesforce without a valid OwnerId.
Migrate accounts and contacts before matters before time entries
Salesforce foreign-key constraints require Accounts to exist before Contacts (via AccountId) and Cases before time entries (via Matter__c lookup). FlitStack sequences the migration in dependency order: Clients → Accounts, then Contacts with AccountId resolution, then Matters → Cases with parent-matter chain resolved, then Time Entries with Case lookup, then Bills with Case and Account links, then document attachments as Salesforce Files. Any circular parent-matter references are flagged and resolved to the most senior matter in the chain before the run commits.
Run a sample migration with field-level diff
A representative slice — typically 200–500 records spanning clients, matters, time entries, and bills — migrates first into a Salesforce sandbox. FlitStack generates a field-level diff comparing source values against destination field values, plus a record-count reconciliation showing the count of records written per object versus the source total. Your team reviews the diff to confirm custom field mapping, pick-list value alignment, and owner resolution before the full production run is scheduled.
Full migration run with delta-pickup window and audit log
The full migration commits all records to production Salesforce. A delta-pickup window — typically 24–48 hours after the run completes — captures any time entries or bill adjustments made in OneAdvanced during the cutover. Every operation is logged in an audit trail with source record ID, destination record ID, field-level before/after values, and the operator who triggered the write. One-click rollback reverts all records written in the migration if reconciliation fails.
