Migrate from Aderant Milana to Mailchimp

Milana's client contact record is the only object that maps directly to Mailchimp. We extract name, email, phone, and address fields and create or update matching Mailchimp contacts. If no email address exists, the record is flagged for manual review before migration day.

Milana matter names and case numbers have no native Mailchimp equivalent. We create a Matter_Name__c merge field and optionally apply a matter-type tag so contacts can be segmented by active case. Closed matters are tagged differently from active ones to distinguish ongoing client relationships.

Practice-area assignments in Milana (Family Law, Civil Litigation, Corporate, etc.) become Mailchimp tags applied to each contact. Tags enable segmentation by specialty for targeted newsletters or practice-area announcements sent to specific client groups. This tagging strategy allows your firm to send relevant content to specific practice area audiences while maintaining a single consolidated contact list in Mailchimp.

The attorney assigned to a Milana matter is surfaced as an Attorney__c merge field on the contact record. This preserves which attorney owns the client relationship and supports attorney-specific client communications in Mailchimp campaigns. The merge field can be used in email personalization to address clients by their responsible attorney or to segment communications by legal team member.

Milana client status (Active, Inactive, Closed) maps to Mailchimp member status (Subscribed, Unsubscribed, Cleaned). We recommend migrating only Active contacts as Subscribed in Mailchimp and excluding inactive or closed records from the initial import to avoid emailing dormant clients. Inactive and closed records can be archived separately for record-keeping purposes without affecting your active audience size.

The original Milana client creation date is preserved as a CLIENT_Since__c date merge field. This supports retention analytics, anniversary-based client communications, and length-of-relationship reporting in Mailchimp. The date field enables your firm to identify long-standing client relationships and create targeted retention campaigns based on client tenure with your practice.

Milana phone numbers migrate to Mailchimp's native PHONE merge field. We validate formats (E.164 normalization for US numbers) and flag any non-digit characters or malformed numbers for cleanup before the import runs. This ensures all phone numbers are properly formatted for any future SMS marketing campaigns or phone-based communications through Mailchimp's integrated tools.

Milana address components (street, city, state, zip, country) map to Mailchimp's native ADDRESS merge field group. Mailchimp stores this as a structured address block rather than individual fields, so the full address appears in Mailchimp's address formatting. This consolidated approach simplifies address management and enables location-based segmentation for event invitations or geographically targeted campaigns.

Milana's rules-based docketing engine and court-rule deadline calculations have no Mailchimp equivalent. This data cannot migrate and is excluded from the migration scope entirely. Firms must retain docketing data in Milana or a comparable legal system to ensure compliance with court deadlines and statute-of-limitations tracking requirements.

Milana calendar events, court date reminders, and docketing appointments have no Mailchimp equivalent. Mailchimp does not include a calendar, deadline tracker, or legal case management scheduling system. Your firm should maintain a dedicated docketing system to manage court dates and legal deadlines separately from your email marketing platform.

Milana documents, court filings, and case attachments have no Mailchimp equivalent. These files cannot be stored in Mailchimp's content library. Firms needing document access must retain Milana or a document management system alongside Mailchimp for proper storage and retrieval of legal case materials and client documentation.

Milana billing records, invoice history, and trust account transactions have no Mailchimp equivalent. If you need to communicate invoice status to clients, invoice data should be exported separately and communicated outside the Mailchimp migration scope. Consider using a dedicated billing or practice management system for financial communications with clients.

Milana custom fields per contact (e.g., Referral_Source__c, Client_Type__c) are mapped to Mailchimp merge fields. We create merge fields in Mailchimp before the import and map values value-by-value. Pick-list fields are mapped as text or tag-based depending on your segmentation preferences.

Milana staff user accounts and attorney login credentials have no Mailchimp equivalent. Mailchimp user accounts are managed separately through its own admin interface and are not migrated from Milana's user directory. Your firm will need to set up new user accounts in Mailchimp with appropriate permissions for team members who will manage email campaigns.

If contacts have existing tags or group assignments from prior integrations or older systems, we surface them during the migration plan. Tags are applied as Mailchimp tags during import, preserving segmentation history where field values are available from the source data.
