Migrate from CosmoLex to Zoho CRM

Matter hierarchies require flattening to Zoho's flat deal model

CosmoLex supports nested matter structures where a parent matter contains child matters, which themselves may contain sub-matters. Zoho CRM Deals are inherently flat — there is no native parent-child deal hierarchy. We handle this by mapping parent matters directly to Zoho CRM Deals and attaching child and sub-matters as Zoho CRM Related Records with a hierarchy-depth custom field on each related record, or by embedding the full hierarchy path in the Deal description field. This means that when viewing a child matter in Zoho CRM post-migration, your team sees it as a related record on the parent Deal rather than as a nested record. Firms with deep matter nesting (four or more levels) should audit whether the flattened structure meets their reporting needs before migration runs.

Zoho CRM caps fields at 300 per module — CosmoLex custom properties may exceed this

Zoho CRM enforces a maximum of 300 fields per module for standard modules including Accounts, Contacts, and Deals. CosmoLex setups with heavy custom property usage on Client or Matter records — particularly larger firms with decades of matter-specific metadata — can exceed this ceiling. We audit the total custom property count during the discovery phase. If the combined standard plus custom field count for any module exceeds 300, we flag the overflow and work with your team to consolidate fields before migration, either by merging related properties into structured pick-lists or by archiving deprecated properties that are no longer referenced in active workflows.

CosmoLex has no public API — migration relies on export-based extraction

CosmoLex does not expose a public REST or GraphQL API for external data extraction. Data migration from CosmoLex relies on their turn-key migration service or manual CSV export. The turn-key service requires coordination with CosmoLex support and may carry its own fees separate from FlitStack AI's migration fee. CSV exports require manual preparation by your CosmoLex administrator, and nested matter hierarchy data may not export cleanly in a flat CSV format. We document the exact extraction steps required and validate the exported data before field mapping begins. Firms with complex matter structures should allow additional time in the planning phase to ensure export completeness.

Billing and trust accounting data has no native Zoho CRM equivalent

CosmoLex invoices, trust ledger entries, and billing balances are legal-specific financial constructs with no direct equivalent in Zoho CRM's data model. Migrating these as standard CRM fields would distort Zoho's reporting architecture. We preserve CosmoLex billing metadata — outstanding invoice total, trust account balance, last payment date — as read-only custom fields on the relevant Deal for historical reference. However, the full financial transaction history (individual invoice line items, trust disbursements, payment registers) should not be stored in Zoho CRM. We recommend migrating that data to Zoho Books or your preferred accounting platform as a separate step post-migration, using CosmoLex's financial export as the source file.

Zoho CRM API rate limits vary by plan tier and may throttle bulk migration

Zoho CRM API rate limits scale by plan tier: Starter tier allows 500 requests per minute, Professional 2,500 per minute, Enterprise 10,000 per minute, and Ultimate 10,000 per minute with higher burst allowances. CosmoLex data volumes — particularly time entries and activity logs — can number in the hundreds of thousands for established firms. We use Zoho CRM's Bulk API endpoints where available and batch records to stay within rate-limit headers (X-RateLimit-Limit, X-RateLimit-Remaining) on each plan tier. Starter and Standard tier setups may require additional migration window time due to throttling. We confirm your Zoho plan tier during discovery and adjust the migration batch size accordingly.
