Overview
Case.one organizes legal practices around Matters, Clients, Contacts, Tasks, and custom billing fields — a data model tuned for litigation and attorney workflows. Zoho CRM uses a standard Leads/Contacts/Accounts/Deals structure with custom fields, Blueprints, and workflow tools. The migration carries all standard objects (contacts, companies, tasks, notes, attachments) while transforming legal-specific Matter data into Zoho Deals with custom fields for case type, status, and billing rate. Billing and invoice records — a common Case.one artifact — require custom fields in Zoho since no native billing module ships in standard Zoho CRM. We extract via Case.one's API using scoped read access, validate relationships before loading, then re-upload attachments to Zoho's file storage within the 25 MB per-file limit. Workflows, automations, and templates do not migrate; we deliver a workflow-definition export as a rebuild reference for your Zoho admin. A delta-pickup window captures any matters or contacts modified during the cutover window.
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 Case.one object lands in Zoho CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Case.one
Matter / Case
Zoho CRM
Deals
1:1Case.one Matters map to Zoho Deals. The Matter name becomes Deal name; case number, case type, and status become custom fields on the Deal. Case type and status values require value-by-value pick-list mapping between Case.one's legal-status pick-list and Zoho's StageName pick-list. Attorney assignment maps to Zoho OwnerId via email resolution.
Case.one
Client
Zoho CRM
Accounts
1:1Case.one Clients map directly to Zoho Accounts. Client name becomes Account Name; client address, phone, and domain map to Account fields. Multiple contacts per client collapse to a primary AccountId with secondary contacts linked via Account Name matching. Client hierarchies — parent and subsidiary clients — map to Account.ParentAccountId.
Case.one
Contact (Attorney / Client Contact)
Zoho CRM
Contacts
1:1Case.one attorney and client contacts map 1:1 to Zoho Contacts. First name, last name, email, phone, and address fields transfer directly. Attorney contacts flagged with a role property migrate as Contacts with a custom Role__c pick-list field to distinguish from client-facing contacts.
Case.one
Task / To-Do
Zoho CRM
Tasks
1:1Case.one tasks and to-do items map to Zoho Tasks. Subject becomes Task Subject; due date maps to Due Date; priority maps to Priority pick-list. Completed status maps to Status='Completed'. Attorney-assigned tasks resolve OwnerId by email match. Tasks without a due date land with no Due Date in Zoho.
Case.one
Time Entry / Billable Hours
Zoho CRM
Tasks (custom fields)
1:1Case.one billable time entries do not have a native Zoho equivalent in standard CRM. We map them as Zoho Tasks with custom fields: Billable_Hours__c (decimal), Billing_Rate__c (currency), and Invoice_Reference__c (text). This preserves attorney billing data for reconciliation in Zoho or downstream invoicing tools.
Case.one
Document / Attachment
Zoho CRM
Attachments / Files
1:1Case.one document attachments on matters and clients re-upload to Zoho CRM's Files module. Files under 25 MB migrate as Zoho Attachments on the corresponding Deal or Account record. Files exceeding 25 MB are flagged before migration so your team can split or host externally. Inline documents within notes are downloaded and reattached as separate files.
Case.one
Note / Case Note
Zoho CRM
Notes
1:1Case.one case notes and internal memos map to Zoho Notes attached to the corresponding Deal or Contact record. Note content preserves plain text and rich-text formatting where Case.one supports it. Note create dates migrate as created datetime; note author resolves to Zoho OwnerId by email.
Case.one
Custom Field (Case-level)
Zoho CRM
Custom Field on Deals
1:1Case.one custom fields at the Matter level — such as court jurisdiction, opposing counsel, or litigation phase — create as custom fields on the Zoho Deals module via the Zoho CRM v8 Field API. Field data types (pick-list, text, date, currency) map directly to equivalent Zoho field types. Multi-select pick-lists in Case.one map to Zoho Multi-Select pick-lists.
Case.one
User / Attorney
Zoho CRM
Users
1:1Case.one attorneys and staff users resolve to Zoho CRM Users by email address match. Unmatched users are flagged before migration so your Zoho admin can invite them first. Users who are inactive in Case.one land as inactive Users in Zoho with their records assigned to a designated fallback owner.
Case.one
Workflow / Automation Rule
Zoho CRM
Blueprint / Workflow Rules
1:1Case.one workflow rules and matter-sequence automations do not migrate — they are not stored as data records but as platform logic. FlitStack exports your Case.one workflow definitions as a written reference document so your Zoho admin can rebuild them in Blueprint and workflow rules. Revenue-critical automations (matter-stage notifications, client alerts) should be rebuilt first.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Case.one gotchas
Trust account balance migration requires financial reconciliation
Per-active-case pricing means closed matters do not count toward billing
Custom field schemas are firm-specific and require enumeration
Large document repositories may require chunked export with integrity verification
Zoho CRM gotchas
API access requires Professional tier or above
Subform fields do not export cleanly via CSV
API credit consumption is non-linear
Export download links expire in 7 days
Owner (User) assignments require pre-mapped user IDs
Pair-specific challenges
Migration approach
Stand up Zoho CRM module and custom-field schema
FlitStack reviews your Case.one data export — module list, custom field definitions, pick-list values, and relationship graph — then creates a Zoho CRM schema plan before a single record loads. We pre-create all custom fields on the Deals, Accounts, Contacts, and Tasks modules using the Zoho CRM v8 Fields API. This includes multi-select pick-lists for case_type and contact_role, currency fields for billing_rate, and text fields for source IDs. Your Zoho admin approves the schema plan before migration begins so the destination is ready when data arrives.
Build owner resolution table and validate Zoho user accounts
We extract every Case.one user — attorneys, paralegals, and staff — and match them against your Zoho CRM user list by email address. Users present in Zoho get their OwnerId mapped automatically. Users not yet in Zoho are flagged with the Case.one user record count so your admin knows exactly how many invitations to send. We do not assign matters to placeholder owners; every record lands with a verified Zoho OwnerId or a designated fallback owner nominated by your team.
Migrate in dependency order: Accounts → Contacts → Deals → Tasks → Notes → Attachments
Zoho CRM requires parent records to exist before child records can reference them. We sequence the migration so Accounts (from Clients) load first, then Contacts, then Deals (from Matters) with their Account_Name and OwnerId lookups resolved. Tasks follow Deals so they can link to the correct matter and owner. Notes and Attachments load last, attached to their parent records by ID. Billing time entries migrate as Tasks with custom fields after the standard task load. We flag any circular or broken foreign-key references before each phase commits.
Run a sample migration with field-level diff
A representative slice of 100–500 records — spanning matters, contacts, accounts, tasks, and attachments — migrates first against a Zoho sandbox or the target instance. FlitStack generates a field-level diff comparing source and destination values for every mapped field. You verify that case_type custom fields populated correctly, billing_rate currency values rounded as expected, attorney ownership resolved by email, and attachment files appear on the correct records. No record commits to production until you sign off on the diff.
Execute full migration with delta-pickup window
The full migration runs against your Zoho CRM production instance. A delta-pickup window of 24–48 hours at the end captures any Case.one records created or modified during the cutover. FlitStack logs every API operation to an audit trail: records inserted, updated, or skipped, with error codes. If reconciliation finds discrepancies — record counts off, attachment missing, or custom field blank — one-click rollback reverts the instance to pre-migration state. Your team can then inspect the failure, correct the field mapping, and re-run the specific module without restarting the full migration.
