Overview

What this migration involves

Aderant Expert and Microsoft Dynamics 365 Sales occupy fundamentally different positions in the legal-technology stack. Aderant Expert is a desktop-based practice management system built for AmLaw 200 law firms — its data lives in Microsoft SQL Server, and its core objects center on Matters, Clients, Billers, Time Entries, and eBilling Guidelines. Dynamics 365 Sales is a cloud-native CRM running on Dataverse whose standard objects are Accounts, Contacts, Leads, and Opportunities. The migration must translate a legal billing model into a commercial CRM model while preserving what matters: client relationships, matter context, biller attribution, and historical time entries. FlitStack AI accesses Aderant Expert through direct SQL Server connections using Windows-authenticated credentials with read-only access scoped to the expert database. We extract Matters, Clients, Billers, Contacts, Time Entries, and any custom fields your firm has added to those tables. On the Dynamics side, we write to Dataverse using the Dynamics Web API — creating Accounts for Aderant Clients, Opportunities for Aderant Matters, and Contacts for billers and client contacts. Custom fields migrate to custom columns on the appropriate Dataverse table (Account, Contact, Opportunity). Workflows, billing rules, conflicts-check logic, and eBilling gateway configurations do not migrate — they must be rebuilt using Power Automate and Dynamics workflows post-migration. The data extraction mechanism matters because Aderant Expert has no public API — extraction happens at the database layer, which requires administrator credentials and careful handling of foreign-key relationships (Client ID on Matter records, Biller ID on Time Entries). FlitStack AI sequences the migration so foreign keys resolve correctly: Clients first, then Matters linked to those Clients, then Billers, then Time Entries linked to Matters and Billers.

Why teams make this switch

Two sides of the same decision

Leaving

Aderant Expert logo

Aderant Expert

What's pushing teams away

  • The invoice payment status workflow is confusing and opaque — users report difficulty determining whether an invoice has been paid, leading to duplicate payments and accounting errors.
  • The user interface is heavily click-driven, requiring excessive navigation to complete routine tasks, which frustrates staff and slows down timekeepers during daily use.
  • Complex and lengthy onboarding process compared to modern SaaS alternatives — G2 reviewers consistently note the challenging initial learning curve.
  • High total cost of ownership for on-premises Expert deployments due to hardware, infrastructure, IT maintenance, and version upgrade management requirements.
  • Modern cloud-native legal platforms (Clio, Litify) offer simpler setup, better integration ecosystems, and lower barriers to entry for mid-market firms.

Choosing

Microsoft Dynamics 365 Sales  logo

Microsoft Dynamics 365 Sales

What's pulling them in

  • Deep Microsoft 365, Teams, and Outlook integration makes Microsoft Dynamics 365 Sales a natural fit for Microsoft-first organizations already invested in that ecosystem
  • Sales Enterprise and Premium tiers offer unlimited custom tables and advanced AI-driven forecasting and predictive analytics not available in lower tiers
  • Professional tier pricing at $65 per user per month offers a lower entry cost than Salesforce for SMB teams with straightforward CRM needs
  • Flexible customization options allow businesses to build bespoke apps, tailor forms and views, and integrate with other Dynamics 365 modules
  • Microsoft Copilot AI tools are embedded directly into the sales workflow on Enterprise and Premium, automating routine tasks and providing deal intelligence

Object mapping

How Aderant Expert objects map to Microsoft Dynamics 365 Sales

Each row shows how a Aderant Expert object lands in Microsoft Dynamics 365 Sales , including any object-level transformations, lookup resolution, or schema-design dependencies.

Typical mapping — final map is confirmed during the sample migration step.

Aderant Expert

Client

maps to

Microsoft Dynamics 365 Sales

Account

1:1
Fully supported

Aderant Clients map to Dynamics Accounts. The Client record's company name, address, phone, and status (Active/Archived) transfer as Account.Name, Account.Address fields, Account.Telephone, and Account.StatusCode. Client ID is preserved as a custom field (Client_ID__c) for traceability and foreign-key resolution when migrating related Matters.

Aderant Expert

Client Contact

maps to

Microsoft Dynamics 365 Sales

Contact

1:1
Fully supported

Contacts stored under each Aderant Client map to Dynamics Contacts linked to the corresponding Account via AccountId. The primary contact name, email address, phone number, and role (Billing Contact, Administrative Contact) transfer directly. Multiple contacts per client collapse to individual Contact records all pointing to the same AccountId.

Aderant Expert

Matter

maps to

Microsoft Dynamics 365 Sales

Opportunity

1:1
Fully supported

Aderant Matters map to Dynamics Opportunities because both represent tracked business engagements with open dates, close dates, values, and status. Matter number and title combine as Opportunity.Name. The Client ID foreign key links to the Account. Matter status (Open/Closed/On Hold) maps to Opportunity.StateCode. Billing method and fee arrangement become custom fields on the Opportunity record.

Aderant Expert

Biller (Attorney / Paralegal / Staff)

maps to

Microsoft Dynamics 365 Sales

User

1:1
Fully supported

Aderant Billers represent the firm's timekeepers — attorneys, paralegals, and administrative staff who log time. Billers map to Dynamics Users resolved by email match against your Dynamics tenant. The Biller's name, email, and role classification (Attorney, Paralegal, Admin) transfer, with role preserved as a custom field (Biller_Role__c) until your Dynamics admin assigns the appropriate Dynamics security role.

Aderant Expert

Time Entry

maps to

Microsoft Dynamics 365 Sales

Task

1:1
Fully supported

Aderant Time Entries track billable and non-billable time logged against a Matter by a Biller. Each Time Entry maps to a Dynamics Task with the associated Contact (as regardingobjectid) and Opportunity (as regardingobjectid). Entry date, duration in hours, activity description, billing status, and biller attribution are preserved. Billable/non-billable flags become custom fields since Dynamics Tasks lack a native billing-status field.

Aderant Expert

eBilling Guideline

maps to

Microsoft Dynamics 365 Sales

Custom Entity (eBilling_Guideline__c)

1:1
Fully supported

Aderant eBilling Guidelines define client-specific billing rules — LEDES format requirements, expense caps, billing frequency, invoice approval routing. These have no direct Dynamics equivalent. We create a custom Dataverse table (eBilling_Guideline__c) linked to Account, storing the guideline text as a large-text field and individual rule components (frequency, format, approval_routing) as structured custom fields.

Aderant Expert

Conflicts Check Record

maps to

Microsoft Dynamics 365 Sales

Custom Entity (Conflicts_Check__c)

1:1
Fully supported

Aderant tracks conflict-of-interest check results as a separate entity linked to Client records. Dynamics has no native conflicts entity. We create a custom Conflicts_Check__c table linked to Account, storing the check date, parties searched, results summary, and clearance status as structured custom fields. The original conflict-check logic in Aderant must be rebuilt using Power Automate or a third-party conflicts-check integration.

Aderant Expert

Document / Attachment

maps to

Microsoft Dynamics 365 Sales

SharePoint / Note

1:1
Fully supported

Aderant stores matter documents and client files on local or network drives linked via SQL paths. We extract file metadata (name, type, size, path, created date) and re-upload to Dynamics' connected SharePoint site (via the native SharePoint integration) linked to the corresponding Account or Opportunity. Actual binary files are re-hosted; the original SharePoint URL is stored as a custom field on the record.

Aderant Expert

Invoice / Bill Record

maps to

Microsoft Dynamics 365 Sales

Invoice

1:1
Fully supported

Aderant invoices map partially to Dynamics Invoices — both include invoice number, amount, date, client reference, and line items. However, Aderant's LEDES 1998B formatting, multi-currency support, and client-specific invoice templates do not transfer. We migrate invoice header data and line-item summaries; the formatted invoice PDF is preserved as a SharePoint-attached document linked to the Invoice record.

Aderant Expert

Custom Fields (Matter)

maps to

Microsoft Dynamics 365 Sales

Custom Columns on Opportunity

1:1
Fully supported

Aderant Matter tables frequently contain firm-specific custom columns beyond the standard schema. We audit the Aderant SQL schema before migration, create corresponding custom columns on the Opportunity Dataverse table, and migrate the values directly. Custom fields with lookup relationships to other Aderant tables require additional mapping logic to resolve the foreign key.

Aderant Expert

Custom Fields (Client)

maps to

Microsoft Dynamics 365 Sales

Custom Columns on Account

1:1
Fully supported

Firms commonly add custom fields to the Client table (e.g., referral source, client tier, billing preferences). We create matching custom columns on the Account table in Dataverse and migrate values. Multi-select or pick-list fields in Aderant are mapped to Dataverse Option Sets with value-by-value correspondence.

Aderant Expert

Billing Rate Table

maps to

Microsoft Dynamics 365 Sales

Custom Entity (Billing_Rate__c)

1:1
Fully supported

Aderant stores attorney and paralegal hourly rates per matter or per client. Dynamics has no native rate-card entity. We create a custom Billing_Rate__c table linked to the User (Biller) and optionally to Account, storing the rate, effective date, and rate type (Hourly, Fixed, Contingency). Rate-based invoice generation requires Power Automate workflows post-migration.

Pair-specific challenges

  • Aderant's SQL Server extraction requires elevated credentials and schema knowledge

    Aderant Expert stores its data in Microsoft SQL Server, not behind a public API. Migration access requires Windows-authenticated SQL credentials with read access to the expert database and the specific schema your firm's Aderant administrator can identify. If Aderant runs on a remote server (RDP-hosted), the extraction window may be constrained by IT access policies. FlitStack AI requires a read-only SQL account scoped to the expert database — broad db_owner access is not necessary and should not be granted. We do not modify Aderant data during extraction.

  • Custom fields in Aderant require pre-migration schema audit

    Aderant Expert firms commonly add custom columns to the Matter, Client, and Biller tables to track firm-specific data (client tier, billing arrangement, practice group, originating partner). These columns appear as additional SQL fields beyond the standard Aderant schema. Before migration, FlitStack AI performs a schema audit against your SQL database to identify all active custom fields, their data types, and any foreign-key relationships they carry. Custom fields with lookup relationships to other Aderant tables must be mapped separately to resolve the foreign key at migration time. This audit step adds 1–2 days to the planning phase.

  • Dynamics Professional tier caps custom columns at 15 per table

    Microsoft Dynamics 365 Sales Professional licenses allow a maximum of 15 custom columns per Dataverse table. If your Aderant custom fields exceed 15 per mapped entity (Client, Matter, Biller, TimeEntry), you will need a Sales Enterprise or Premium license to accommodate the full schema, or FlitStack AI must consolidate multiple Aderant custom fields into structured JSON or text fields on the destination record. Enterprise and Premium tiers allow unlimited custom columns. Firms with complex eBilling guideline fields or multi-column rate structures frequently hit this cap on the Professional tier.

  • Biller-to-User email resolution may leave orphaned time entries

    Aderant Billers are internal firm users who may not have corresponding email addresses in your new Dynamics 365 tenant if they are not licensed users (e.g., contract attorneys, Of Counsel not on the Dynamics subscription). FlitStack AI resolves Biller records to Dynamics Users by email match. Unmatched Billers are flagged before migration with a fallback assignment to a designated migration owner. Time entries attributed to unmatched Billers land in Dynamics under that fallback owner, with the original Biller ID preserved in a custom field. Your firm decides whether to reassign those entries post-migration or leave them attributed to the fallback owner.

  • eBilling and LEDES invoice formats cannot be reconstructed in Dynamics natively

    Aderant Expert generates invoices in LEDES 1998B and other legal-billing formats required by corporate clients and courts. Microsoft Dynamics 365 Sales does not include legal billing formats, LEDES export, or eBilling gateway integration. We migrate invoice header data and line items to Dynamics Invoices, and the original invoice PDF to SharePoint, but the formatted LEDES output cannot be regenerated from Dynamics data without custom Power Automate workflows or a third-party legal billing integration. Firms that rely on LEDES export for client invoicing must plan for a separate eBilling integration (e.g., InvoiceCloud, LegalSIze) post-migration.

Migration approach

Six steps for a successful Aderant Expert to Microsoft Dynamics 365 Sales data migration

  1. Obtain SQL Server read access and perform schema audit

    FlitStack AI requests a read-only SQL Server login scoped to the Aderant expert database. Your Aderant administrator grants the account and confirms the database name and schema. We then run a schema-audit query against the master tables (Client, Matter, Biller, TimeEntry, and any firm-added custom columns) to produce a complete field inventory with data types, nullability, and foreign-key relationships. This audit output drives the field-mapping plan and identifies any custom fields that will require custom Dataverse columns or Enterprise-tier licensing.

  2. Provision Dynamics 365 tenant and create custom Dataverse schema

    Before data moves, your Dynamics administrator (or FlitStack AI in consultation with your team) creates the custom Dataverse tables and columns identified in the schema audit: eBilling_Guideline__c, Conflicts_Check__c, Billing_Rate__c, and any custom fields on Account, Contact, and Opportunity. If your firm runs Sales Professional, we validate that the custom field count per table fits within the 15-column limit or recommend an Enterprise upgrade. Dynamics security roles for Billers are mapped from their Aderant role classification. This step requires your tenant to be licensed and the Dataverse environment accessible via the Dynamics Web API.

  3. Resolve Biller records to Dynamics users by email

    We extract the full Biller list from Aderant SQL and attempt to match each Biller's email address to an existing user in your Dynamics 365 tenant. Matched Billers become the OwnerId on migrated Time Entries and Opportunities. Unmatched Billers are flagged in a pre-migration report — your team either creates a corresponding Dynamics user for each unmatched Biller or assigns them to a fallback owner. This step ensures that time-entry attribution is correct before the migration run commits data to Dynamics.

  4. Run sample migration with field-level diff

    A representative slice of records — typically 50–200 per entity type (Clients, Matters, Billers, Time Entries) — migrates to a Dynamics sandbox environment first. FlitStack AI generates a field-level diff comparing source SQL values against the Dynamics record values. You review the diff to confirm that custom field values populated correctly, that Biller attribution resolved as expected, and that matter-to-opportunity linkage (via AccountId) is intact. Sample migration validation typically runs over 24 hours and is a prerequisite for the full run.

  5. Execute full migration with delta-pickup window

    The full migration extracts all Aderant records, transforms them per the field-mapping plan, and writes to the Dynamics production environment. A delta-pickup window of 24–48 hours captures any changes made in Aderant during the cutover period (new time entries, status changes, new clients). FlitStack AI uses the Dynamics Web API with Dataverse bulk-write operations to load records in batches, maintaining original create/modify timestamps where the API permits. An audit log records every operation, and one-click rollback reverts the Dynamics environment to its pre-migration state if reconciliation identifies critical data integrity issues.
