Overview
Moving from Corteza CRM to Zoho CRM is a self-hosted-to-SaaS migration that requires handling schema differences, namespace export edge cases, and workflow remediation before any records move. Corteza organizes CRM content into namespaces with a JSON export path that explicitly fails when any page references a deleted module; we audit for orphaned page references first so the namespace package can complete cleanly. Workflow definitions in Corteza are known to break after system restore or upgrade, so we capture them during discovery and deliver a written inventory for rebuild in Zoho rather than attempting a direct migration. We migrate Accounts, Contacts, Opportunities, Cases, Campaigns, Tasks, Custom Modules, and historical activity records via Zoho's Data Migration wizard for CSV imports and REST API for custom object work, respecting the 5GB per-file and 25GB total import limits. Automations, Sequences, and Reports do not migrate as code; we document them for your Zoho admin to rebuild post-migration.
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 Corteza CRM 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.
Corteza CRM
Lead
Zoho CRM
Lead
1:1Corteza CRM Lead records map directly to Zoho CRM Leads. Standard fields (first name, last name, email, phone, rating) align with Zoho's Lead field names. The lead conversion workflow in Corteza creates Accounts, Contacts, and Opportunities; we preserve the conversion metadata (original lead ID, conversion timestamp) in a custom Zoho field for audit trail purposes. Lead status and source fields map to Zoho's standard picklist fields, and any custom lead fields migrate as custom fields in Zoho.
Corteza CRM
Account
Zoho CRM
Account
1:1Corteza CRM Accounts (companies) map directly to Zoho CRM Accounts. The account name becomes the Account Name field, industry classification maps to Zoho's Industry picklist, and address data migrates to Zoho's address compound field. Social media URLs migrate to custom URL fields. Account is created before Contact import so that the Account-Contact lookup relationship is satisfied at the moment of Contact insert.
Corteza CRM
Contact
Zoho CRM
Contact
1:1Corteza CRM Contacts map to Zoho CRM Contacts. Each Contact's relation to a parent Account migrates as a Lookup field resolved at migration time using the Account name dedupe key. Standard fields (first name, last name, email, phone, job title) align with Zoho's field names. If the source Corteza instance uses a flat contact model without Account linkage, we create placeholder Accounts during migration to satisfy Zoho's Account-Contact relationship requirement.
Corteza CRM
Opportunity
Zoho CRM
Deal
1:1Corteza CRM Opportunities map to Zoho CRM Deals. The opportunity stage maps to Zoho's Stage picklist, amount maps to Amount, probability maps to Probability (as integer), and close date maps to Closing Date. Each Deal can relate to an Account and multiple Contacts via Deal Contact Role records. If Corteza Opportunities reference a custom pipeline model, we create Zoho Custom Pipeline Views to preserve the visual stage layout.
Corteza CRM
Campaign
Zoho CRM
Campaign
1:1Corteza CRM Campaigns map to Zoho CRM Campaigns with campaign member associations preserved via Campaign Member records linking Contacts and Leads to the Campaign. Campaign type, status, start date, and budget migrate to Zoho's corresponding fields. Campaign member response tracking (sent, opened, clicked, converted) maps to Zoho Campaign Member Status values.
Corteza CRM
Case
Zoho CRM
Case
1:1Corteza CRM Cases migrate to Zoho CRM Cases with status, priority, origin, and resolution fields mapped directly. Case-Account and Case-Contact relationships are resolved at migration time using Account name and Contact email as dedupe keys. If the source Corteza instance uses a custom case numbering scheme, we create a Zoho custom field to preserve the original case ID for reference.
Corteza CRM
Task
Zoho CRM
Task
1:1Corteza CRM Tasks map to Zoho CRM Tasks. Standalone tasks and tasks related to any parent record (Lead, Account, Contact, Opportunity) both migrate with their Status, Priority, Due Date, and Assignee preserved. Task assignees resolve via email match against Zoho User records, with unresolved owners placed in a reconciliation queue for your Zoho admin to provision.
Corteza CRM
Event
Zoho CRM
Event
1:1Corteza CRM Events (meetings, calls) migrate to Zoho CRM Events with Start DateTime, End DateTime, and Location preserved. Event parent-record linkage (which CRM record the meeting was related to) migrates as Event-Account and Event-Contact relations resolved via dedupe keys at migration time. Organizer and attendee references map to Zoho User and Contact records via email matching.
Corteza CRM
Quote
Zoho CRM
Quote
1:1Corteza CRM Quotes migrate to Zoho CRM Quotes with QuoteLineItems preserved as line items under each Quote. The parent Opportunity (Deal in Zoho) reference is resolved at migration time using the Deal name as the dedupe key. Pricing information migrates to Zoho's pricing fields, and terms and conditions text migrates to the Quote description or custom field depending on structure.
Corteza CRM
Product
Zoho CRM
Product
1:1Corteza CRM Products map to Zoho CRM Products with product name, code (SKU), and pricing details preserved. If the source uses Pricebook and PricebookEntry records to manage tiered pricing, we create Zoho Products with multiple Price Details entries to replicate the pricing structure. Product active/inactive status maps to Zoho's Active field.
Corteza CRM
Custom Module
Zoho CRM
Custom Module
1:1Corteza CRM custom modules created via the low-code builder map to Zoho CRM custom modules. We pre-create the destination schema in Zoho before any data import, including all custom fields, field types (text, number, date, lookup, picklist), and any custom validation rules. Custom module records migrate after standard object import so that lookup relationships to standard objects are satisfied. The migration field map documents each custom field's Corteza type and recommended Zoho equivalent.
Corteza CRM
Contract
Zoho CRM
Custom Module (Contract)
1:1Corteza CRM Contracts with ContractLineItem and ContractContactRole structures migrate to a Zoho custom module named Contracts with line item subform fields and a Contact lookup. Contract terms, start and end dates, and related Account reference map to Zoho custom fields. If the destination Zoho org includes Zoho Contracts or Zoho Billing as an add-on, we configure the native module instead of a custom module.

Pair-specific challenges
Migration approach
Discovery and namespace audit
We audit the source Corteza CRM instance across all modules, custom field definitions, namespace structure, and workflow definitions. We specifically look for orphaned page references that would prevent namespace export from completing. We capture the complete list of active workflows, automation buttons, and custom modules with their field configurations. We also inventory engagement history volume (tasks, events, notes) to determine whether Zoho's CSV import limits require batch splitting. The discovery output is a written migration scope, namespace health report, and workflow inventory document.
Schema design and Zoho custom module provisioning
We design the destination schema in Zoho CRM. This includes provisioning custom modules for any Corteza custom modules with field-type mapping (Corteza field types to Zoho field types), creating custom fields for any Corteza fields that have no direct Zoho equivalent, and configuring lookup relationships before any data import begins. We also set up Zoho pipeline stages to align with Corteza opportunity stages and configure any required picklist value sets based on Corteza picklist data observed during discovery.
Workflow and automation inventory handoff
We deliver the captured workflow inventory document to the customer. Each workflow entry includes the Corteza workflow name, trigger type, conditions, actions, and a recommended Zoho equivalent (Workflow, Blueprint, Function, or combination). This is a written document, not migrated code. The customer's Zoho admin or a Zoho partner rebuilds the automations post-migration. We do not rebuild workflows as part of the migration scope.
Data export in dependency order
We export data from Corteza CRM in record-dependency order: Accounts first, then Contacts (with AccountId resolved), Leads, Opportunities (with AccountId and OwnerId resolved), Cases, Campaigns, Tasks, Events, Custom Modules, and historical activity records. If namespace export is blocked by orphaned page references, we fall back to module-by-module API export. Each export produces a CSV with a manifest of record counts per module for reconciliation against the source.
Sandbox migration and reconciliation
We run a full migration into a Zoho CRM sandbox environment using production-like data volume. The customer reconciles record counts against the source instance, spot-checks 25-50 records for field accuracy and relationship integrity, and validates that custom module data landed correctly. Any mapping corrections happen in sandbox before production migration begins. This step also validates that Zoho's import limits are sufficient for the data volume or identifies any batch splitting requirements.
Production migration and cutover
We run production migration in the same dependency order validated in sandbox. We freeze Corteza CRM writes during the cutover window, run a final delta migration of any records modified during the migration period, then enable Zoho CRM as the system of record. We deliver a post-migration reconciliation report comparing source record counts to destination record counts per module, flag any records that failed import with the error reason, and provide a one-week hypercare window for reconciliation issues raised by the customer's team.
